| Economics of Autonomous Strip-Cropping with Professor James Lowenberg-DeBoer | 14 Feb 2025 | 00:34:46 | |
"Economics of strip cropping with autonomous machines" with James Lowenberg-DeBoer. With the growing global population, the demand for food continues to rise. However, increasing food production often depends on intensive farming practices and agricultural inputs that can negatively impact environmental health. To counter this, promoting crop diversity, improving soil health, and reducing disease and pest pressure are crucial. Mixed cropping presents a viable solution but poses challenges for mechanization and labor efficiency. In this context, customized autonomous machines and advanced technology can play a key role in facilitating mixed cropping while lowering production costs. In this episode, Dr. James Lowenberg-DeBoer shares insights from his research on the economics of strip cropping—the simplest form of mixed cropping—using autonomous machines. He explores the feasibility and profitability of this approach, along with the challenges and opportunities in restoring crop biodiversity and ecosystem services, ultimately fostering better environmental health and sustainable agriculture.

| Water Retention Products on Home Lawns with Vikram Baliga | 15 May 2020 | 00:43:34 | |
"Evaluation of Water Retention Products to Conserve Urban Water Resources in Home Lawns" with Vikram Baliga. Water retention products are designed to help turfgrasses conserve water. But as water conservation becomes an issue of ever greater importance, it is important not only to know which of these products to use, but also how best to use them within larger water conservation initiatives. Enter Vikram Baliga and his team. In the field, they compared four different water retention products to see which performed best under harsh, drought like conditions. In tandem, they also sent out surveys to homeowners, investigating what kinds of messaging and incentives might best influence homeowner behaviors.

| Oil Spill Remediation in North Dakota with Dr. Tom DeSutter and Sam Croat | 17 Apr 2020 | 00:38:49 | |
"Crop Production on Heavily Disturbed Soils following Crude Oil Remediation" with Dr. Tom DeSutter and Sam Croat. When an oil spill occurs on land, there are myriad ways to approach cleanup, from adding oxidizers or nutrients to speed natural processes, burning off surface oil, replacing contaminated top soil with top soil from other regions, or even just removing the soil to a landfill. When an oil spill in 2013 contaminated Steve and Patty Jensen's land with ~860,000 gallons of Bakken crude oil, Dr. Tom DeSutter and then student Sam Croat tested soil mixing and thermal desorption methods, working with the oil companies, landowners, and remediation companies to try to see which methods could best return the Jensen's land to its original, pre-spill state.

| Top Ten Plants with Dr. Mary Meyer and Dr. Natalie Bumgarner | 20 Mar 2020 | 00:43:21 | |
"Top 10 Plants: Increasing Awareness of Plants" with Dr. Mary Hockenberry Meyer and Dr. Natalie Bumgarner. Plant blindness is the inability to "see" the plants around us, that is, to recognize them as separate and important pieces of our surroundings beyond their roles as general background or landscape. But for those who do "see" plants and their varied species, how can they communicate that information and passion to those around them? One potential answer? Lists. Drs. Mary Meyer and Natalie Bumgarner are pioneers in this technique, both coordinating with local partners, experts, media, and the public to spearhead Top Ten Plant programs in their states.

| Genome-Wide Association Studies in Apples with Dr. Zoë Migicovsky and Dr. Carsten Pedersen | 17 Jan 2020 | 00:37:01 | |
"Genome-Wide Association Studies in Apple Reveal Loci for Aroma Volatiles, Sugar Composition, and Harvest Date" with Dr. Zoë Migicovsky, Dr. Carsten Pedersen Apple breeding can take a long time. Because each seed is the progeny of two different trees and each tree takes five to six years to produce its first fruits, breeders can be waiting years, if not decades, to see the results of their hard work. Drs. Zoë Migicovsky and Carsten Pedersen are working to change that. By comparing the genomes of varying apple cultivars and their phenotypic data (traits you can discern via the five senses), Zoë and Carsten aim to pinpoint which genes are responsible for which traits. With that information, simple DNA testing may be able to shave years off of each round of breeding, helping breeders create better apples for your shelves in far less time. Listen in to learn:

| Winter Phosphorus Release in Cover Crops with Dr. Merrin Macrae | 20 Dec 2019 | 00:36:19 | |
"Winter Phosphorus Release from Cover Crops and Linkages with Runoff Chemistry" with Dr. Merrin Macrae Cover crops can offer a variety of ecosystem services, including reducing soil erosion. However, in colder climates, where cover crops can freeze and die over the winter, there is the possibility that the Phosphorus within cover crops can then leach into surface runoff. Dr. Merrin Macrae and her team decided to dive deep and discover whether or not this trade-off exists and, if so, to what extent. Listen to learn:

| Methane, Hydrology, and Constructed Wetlands with Karla Jarecke and Dr. Terry Loecke | 15 Nov 2019 | 00:37:34 | |
"Plant Species and Hydrology as Controls on Constructed Wetland Methane Fluxes" with Karla Jarecke and Dr. Terry Loecke Wetlands are important ecosystems that provide many important services, such as assisting in water quality, flood control, erosion protection, carbon removal and storage, and biodiversity. Hydrology is the study of water, specifically in how it moves throughout the landscape. Combine them with the conundrum of methane production in wetland plant species, and you've got the makings of a fascinating research project. Specifically, Karla Jarecke and Terry Loecke's project. By testing methane production in two common wetland species under both lab and field conditions, they worked to answer important questions about not only how methane production, hydrology, and wetland species work together, but also how we can better plan for the creation and care of constructed wetlands.

| What We Mean by Soil Health with Dr. Ryan Stewart | 18 Oct 2019 | 00:40:53 | |
"What We Talk about When We Talk about Soil Health" with Dr. Ryan Stewart. Soil health is an important topic for today's scientists, but how do we quantify it, and when we talk about "healthy soils," what do we even mean? Dr. Ryan Stewart and his team set out to answer just that. Doing a meta-analysis on dozens of studies listed in The Soil Health Institute's Research Landscape Tool, Ryan and his team compared different soil health indicators to determine what scientists are measuring, how they're measuring it, and which are the most valuable in actually determining soil health.

| Saturated Riparian Buffers with Dr. Morgan Davis and Dr. Tyler Groh | 16 Aug 2019 | 00:40:41 | |
"Nitrous Oxide Emissions from Saturated Riparian Buffers: Are We Trading a Water Quality Problem for an Air Quality Problem?" with Dr. Morgan Davis and Dr. Tyler Groh. Riparian buffers are areas of perennial vegetation planted around stream banks and other riparian zones to protect against soil erosion and nutrient leaching. However, tile drainage systems—piping laid under fields to keep them from becoming too saturated—are designed to bypass riparian buffers, leading to potentially harmful levels of nutrient leaching. Saturated Riparian Buffers are a relatively new conservation technique that aims to reduce those water quality issues by redirecting excess water back into the soil. However, their installation could potentially lead to increased levels of incomplete denitrification, resulting in excess nitrous oxide, a potent greenhouse gas, being released into the atmosphere. Drs. Morgan Davis and Tyler Groh work together to examine saturated buffer design and these potential environmental tradeoffs. This episode, listen in to find answers to the following questions:

| Tree Harvesting, Biomass Removal, and Soil Nutrient Reserves with Dr. Dave Morris | 19 Jul 2019 | 00:32:52 | |
"Effects of Biomass Removal Levels on Soil Carbon and Nutrient Reserves in Conifer-Dominated, Coarse-Textured Sites in Northern Ontario: 20-Year Results" with Dr. Dave Morris Forest harvesting varies greatly from annual harvests of agricultural crops, with extended times between harvests, the amount of harvested material removed, and the degree of site disturbance. Trees can grow to impressive sizes, but can take up to 60 years or more to reach a merchantable size. Because of these factors, the potential impact of these forest harvest operations on the environmental conditions needed for successful tree regeneration and growth can be substantial. Dr. Dave Morris, in collaboration with colleagues from the Canadian Forest Service, have been examining the potential impacts of forest biomass removal on the sustainability of these harvesting practices. With his team from the Ministry of Natural Resources and Forestry in Canada and sites from across the North American Long-term Soil Productivity Network, he's spent 25-years looking at how forest soils and the regenerating forest recover after different intensities of forest biomass removal.

| High-Throughput Seed Phenotyping with James Clohessy | 21 Jun 2019 | 00:35:01 | |
"A Low-Cost Automated System for High-Throughput Phenotyping of Single Oat Seeds" with James Clohessy. A Rube Goldberg machine is a machine intentionally designed to complete a simple task using overly complicated steps. James Clohessy and his team are doing just the opposite. Using machine learning, web cameras, open software, and photogrammetry techniques, they're developing low cost, high-throughput, high efficiency phenotyping systems. With these systems, researchers can save hours of time that would normally be spent on taking individual seed measurements by hand, such as height, width, and color, all while gaining greater detail about the seed such as volume and density. Listen in to learn more about James' new system as well as:

| Vadose Zone Gas Migration and Leaking Wells with Olenka Forde | 17 May 2019 | 00:31:15 | |
"Vadose Zone Gas Migration and Surface Effluxes after a Controlled Natural Gas Release into an Unconfined Shallow Aquifer" with Olenka Forde. Olenka Forde thinks a lot about a world that we'll never see – the world existing right underneath our feet. Olenka's research is related to hydraulic fracturing and she is interested in how we can safely extract oil and gas resources without negative impacts on fresh water supply, wildlife, and even humans. She does this by monitoring the fate and transport of gases in the subsurface and emissions at the ground surface at a controlled natural gas release experiment, essentially simulating what happens when a gas well leaks. Gas leakage at oil and gas wells is an old problem, but has garnered renewed interest with the advent of hydraulic fracturing. Hydraulic fracturing is a process that works to free valuable natural gas from beneath rock deep in the earth through injecting a mixture of water, sand, and chemicals at a very high pressure. The gas is released through these cracks and up through a constructed well to the surface for collection. Occasionally; however, sealing of wells is imperfect and gas present along the borehole escapes, causing the potential for groundwater contamination and surface emissions. Olenka works to map the pathway of gases after the point of release, eventually with the goal of creating improved action plans for industry professionals to keep people and the environment safe. Tune in to learn about her research and find answers to questions such as:

| Turfgrass Colorants with Drew Pinnix | 19 Apr 2019 | 00:37:01 | |
"Color, Transfer, and Application Parameters of Turfgrass Colorants" with Garland (Drew) Pinnix. In kindergarten, we're taught that colors can be one of seven colors of the rainbow. Later, we learn fun colors like purple mountain majesty and get excited when our friend brings a 50-pack of crayons. In reality though, color is much more complex, a mixture of hue, brightness, and saturation. Drew Pinnix thinks a lot about color, specifically in relation to turfgrass. Most of the time, the beautiful turfgrass we see at golf courses or football fields is due to careful management by professionals trained in plant science or agronomy. However, sometimes weather or cost restrictions gets in the way, and turfgrass managers look to colorants to get the turfgrass ready for use and for cameras quickly. However, getting a natural color that won't rub off as football players slide in after a fumble is incredibly complicated. That's where Drew's team comes in. He works to scientifically evaluate turfgrass colorants so football fields and golf courses can keep looking gorgeous year-round. Tune in to learn more about Drew's experimental design, turfgrass management, and learn answers to the following:

| Hydrological Observatories with Dr. Heye Bogena | 15 Mar 2019 | 00:41:57 | |
"Toward Better Understanding of Terrestrial Processes through Long-Term Hydrological Observatories" with Dr. Heye Bogena. Hydrology, put plainly, is the study of water: how it moves, where it goes, and what's inside it. Hydrologists gather as much information as they can about water in order to understand current water trends and to predict potential water patterns in the future. In a changing climate, this is more crucial than ever. Using data from multiple networks of hydrological observatories, hydrologists gather information and create and test models surrounding questions such as: How will land use change affect water flux? Will climate change create conditions for more low or high flow events? How can forestation affect frequency of high flow events? They then use this information to create resources for natural resource managers, officials, and the public to make informed decisions. In this episode, we'll take a deeper look at how hydrological observatories are making strides in understanding water and its movement around the world. We'll discuss:

| Precision and Sustainable Agriculture with Dr. David Clay | 15 Feb 2019 | 00:42:13 | |
Precision Agriculture Basics with Dr. David Clay Dr. David Clay, along with the precision agriculture community, are working like codebreakers to crack the secret to more efficient, more environmentally friendly farming. The key? Understanding variability. Across any given farm field, there are many discrepancies in how given points of the field react to similar management practices. If farmers understand what causes those discrepancies, they can fine tune management in ways that can optimize fertilizer and pesticide use, inputs, and time. Getting this type of information used to mean extensive and costly soil sampling. Dr. Clay discusses how tech has made it possible to make great management decisions from data obtained miles above a farm.

| The OSU Hand Planter with Dr. Bill Raun | 18 Jan 2019 | 00:37:15 | |
"Hand Planter for the Developing World: Factor Testing and Refinement" with Dr. Bill Raun Across Central America, South America, and Africa, there are thousands of acres of land with slopes and landscapes that will never be suitable for mechanized agriculture. For hundreds of years, they have been planted by hand, a practice that continues today. The problem is, as technology in chemical seed treatments has advanced, technology in hand-planting techniques has not, resulting in thousands of farmers' exposure to seed-friendly chemicals that can lead to sickness and even birth defects in humans. After splitting much of his childhood and early career between North, South, and Central America and seeing the results of this exposure, Dr. Bill Raun decided it was time to do something about it. Working with engineering students and professors at Oklahoma State University, he has spent more than 20 years developing a new hand planter that will work with existing hand-planting techniques to increase yields and get good, chemically treated seed out of farmers' hands.

| Sediment and the Health of the Great Barrier Reef with Dr. Peter Hairsine | 21 Dec 2018 | 00:39:12 | |
"Review: Sediment-Related Controls on the Health of the Great Barrier Reef" with Dr. Peter Hairsine. In 2016, a catastrophic bleaching event killed off around 30% of the Great Barrier Reef's coral. The reef has been in a precarious spot for decades, but climate change and human-caused pollution have amplified the threats to its existence. Dr. Peter Hairsine is a scientist with The Fenner School of Environment and Society, The Australian National Univ., Canberra, Australia, working on the front lines of monitoring and researching the reef's responses to these changes, with an ultimate goal of preserving it as one of the world's richest and most unique ecosystems. Join us as Dr. Hairsine and I discuss the stresses that the Great Barrier Reef (GBR) currently experiences. Warming ocean temperatures, deteriorating river water quality, and tropical storms all threaten the fragile coral that houses thousands upon thousands of native species. You'll learn the three ecosystems of reef within the GBR, as well as the sources of sediment and attached pollutants that currently feed into it. Also in the episode:

| Stacking Soybean Cyst Nematode Resistance with Dr. Brian Diers | 16 Nov 2018 | 00:33:06 | |
"Pyramiding of Alleles from Multiple Sources Increases the Resistance of Soybean to Highly Virulent Soybean Cyst Nematode Isolates" with Dr. Brian Diers. One of a farmer's greatest enemies is a nemesis that they never even see. A nematode sounds like a ghastly swamp monster – in reality, it's a microscopic worm that does some big time damage to soybean fields. These little guys love living in the soil and sucking on soybean roots. A bad infestation of soybean cyst nematodes can cost a farmer around 30 to 40% of his or her crop. So how does one fight a nemesis that is too small to see? You build up a resistance. That's what Dr. Brian Diers is developing through his soybean breeding research. He's been working with crop wild relatives, soybean varieties, and plant breeders to identify sources of resistance and ways to incorporate that resistance into soybean. This process is a race against time. Resistant soybean varieties are almost entirely from a single source. Nematodes are becoming more and more capable of overcoming this resistance.

| Wildland Fire, Mercury, and Perch with Dr. Randy Kolka and Trent Wickman | 19 Oct 2018 | 00:38:41 | |
"Yellow Perch (Perca flavescens) Mercury Unaffected by Wildland Fires in Northern Minnesota" with Dr. Randy Kolka and Trent Wickman. We often hear of the dangers of mercury to pregnant women and children that require them to restrict fish consumption. For good reason – even at low concentrations, mercury can do serious damage to neural networks and reproductive systems. However, we talk little of how the mercury gets in these fish in the first place. The most common way mercury enters the ecosystem is through the burning of coal; however, it can also volatilize via prescribed and wild fires in forests. From there, it can redistribute into other parts of the ecosystem, such as lakes, and work its way into the food chain. This can hurt the animals that rely on lakes or the fish that live in them to survive. It can also hurt people. For Dr. Randy Kolka and Trent Wickman of the USDA Forest Service, who love the people and wildlife of Northern Minnesota – they had to know more. They set up a study on two lakes – one that hadn't seen a fire in over 100 years and one that had a serious fire that covered over 99% of the watershed – and sampled soil, water, and fish to compare mercury levels. In this episode, they discuss their experimental design, along with a breakdown of the realities of fieldwork. It can be tough carrying heavy equipment or samples of lakewater, let alone camping gear and food; they discuss how they made choices on what to bring, how samples were collected, and how they managed the logistics of the trips.

| Crop Wild Relatives Week with Dr. Stephanie Greene | 21 Sep 2018 | 00:39:16 | |
"An Inventory of Crop Wild Relatives of the United States" with Dr. Stephanie Greene. Crop Wild Relatives week is September 22 – 29, 2018! Crops are vital to feeding an expanding world – and like anything incredibly important, they need to be protected from things like disease, environmental disaster, and anything else that can pose a real threat. The key to their protection? Unexpected heroes that could be growing in your back yard– wild varieties of domesticated crops called crop wild relatives. Crop wild relatives are the close cousins of domesticated crops (think a poodle vs. a wolf). Often, these crops are well-adapted to their environment and can exhibit wild superpowers such as drought or disease resistance. And because they are so closely related to domesticated crops, scientists can cross them with crops that people rely on for food or other uses, such as wheat or blueberries. The result – stronger, healthier crops– and peace of mind that your favorite blueberry muffins will be available for years to come. Dr. Stephanie Greene and seedbanks around the world have made it their mission to catalog, protect, and educate the public on these wild, unruly cousins of crops and how scientists use them to give our favorite crops super strength. This year, for Crop Wild Relatives week, tune in to find answers to the following questions and more:

| The Farm Bill with Dr. Julie McClure and Dr. Elizabeth Stulberg | 07 Sep 2018 | 00:48:50 | |
The Farm Bill with Dr. Julie McClure and Dr. Elizabeth Stulberg If you have ever eaten food in the United States, you've been impacted by The Farm Bill, a mega-bill that is due for renewal in Congress this September. Although it heavily affects farmers, the Farm Bill covers a huge swath of topics: wildlife conservation, rural affairs, agriculture research, food stamps, and a lot more. If it seems like a big and overwhelming deal, that is because it is. Luckily, we have Drs. Elizabeth Stulberg and Julie McClure, two ASA-CSSA-SSSA science policy managers that are fluent in scientific research and the ins and outs of Washington politics to be our guides. For our membership, they work as translators between scientists and policymakers. Scientists want to know about relevant happenings in D.C. and new available funding opportunities; policymakers want to know new science that could impact their legislative districts. We discuss the amazing history of the Farm Bill, how the bill will move through Congress this September, and what happens to the $1 trillion that is slated to be budgeted for this next Farm Bill. As it turns out, passing an important bill (especially a bill that affects so many) is hard! Put your learning caps on, because we're about to take a deep dive into the process of how a concept grows from idea into a large-scale part of our daily lives. Tune in to learn:
Please note: At around 32:00 Dr. McClure says FFAR funds have to be matched by public funding, but in fact they must be matched by private (non-federal) funding.

| Climate Change and Simulated Canola Yields with Dr. Budong Qian | 17 Aug 2018 | 00:28:28 | |
"Simulated Canola Yield Responses to Climate Change and Adaptation in Canada" with Dr. Budong Qian. Canada really cares about the future of canola. It has surpassed spring wheat as the dominant crop in Canada, covering 8.5 million ha of Canadian agricultural land. It is even named after Canada, as the word canola itself is a contraction of "Canada" and "oil". However, climate change and increasing temperatures threaten Canada's canola sector—which is why Agriculture and Agri-Food Canada has constructed a team of scientists to study the future of canola and Canada's agricultural areas, which are projected to have a 3 to 3.5 °C increase in temperatures within the next 30 years.

| Pipeline remediation timelines with Theresa Brehm | 15 Nov 2024 | 00:37:40 | |
"Soil degradation and crop yield declines persist 5 years after pipeline installations" with Theresa Brehm. Underground pipeline installations are crucial for energy supply, helping to meet rising demand. However, these installations can significantly impact agricultural lands due to soil excavation, heavy machinery use, and resulting soil disturbances. Although companies typically offer support to farmers for up to five years, claiming that soil health and productivity are restored within that period, many farmers report ongoing issues with soil degradation and reduced crop yields. This highlights the need to evaluate the true impact of pipeline installations on soil health and crop productivity and to assess the effectiveness of remediation efforts in restoring soil vitality. In this episode, Theresa Brehm shares insights from her research on assessing the impacts of pipeline installations on soil health and agricultural productivity in Ohio state, along with insights from farmers' experiences.
Tune in to learn: · What are the impacts of underground pipeline installations on soil health and crop productivity? · How are farmers compensated for their losses? · How do pipeline installations affect soil texture, porosity, and crop yields? · How effective are company-led land remediation efforts in restoring soil health and productivity? · What are the long-term challenges of restoring soil health after pipeline installations?

| Insect Pollinators and Confection Sunflowers with Dr. Rachel Mallinger | 19 Jul 2018 | 00:41:08 | |
"Benefits of Insect Pollination to Confection Sunflowers Differ Across Plant Genotypes" with Dr. Rachel Mallinger. Sunflowers are a hallmark of an American summer. They're grown for beauty, but they are also important industrial crops in America, grown for sunflower oil, for fresh eating (of the seeds), and for bird seed. And although we've slowly bred them to be more independent of pollinators, sunflowers still partner with bees. And not just honey bees. More often, they partner with native bees. Did you know honey bees aren't even native to the U.S.? And while just as charismatic in their own way, native bees might not fit the usual description of a bee that we imagine. Most U.S. bees don't have a colony, don't have a queen, and don't have a hive that sits in a tree. And yet these mostly underground, solitary dwellers are the ones that are so important for sunflowers (and many flowers). Dr. Mallinger's research looks at the fascinating relationship between these species – the confection sunflower and native bees. She wants to be able to measure this relationship. How do sunflowers benefit from pollination by bees? Tune in to learn more about Dr. Mallinger's research and to find answers to these questions:

| Artificial Sweeteners Underground with Dr. John Spoelstra | 13 Jun 2018 | 00:30:18 | |
"Artificial Sweeteners Reveal Septic System Effluent in Rural Groundwater" with Dr. John Spoelstra. Dr. John Spoelstra is something like a wastewater detective. If there is secret wastewater that is contaminating groundwater and putting health outcomes at risk, he wants to know. To trace the path of wastewater, he uses a special set of tools: tracer compounds. These are compounds that are not found in the natural environment, but have a lot of human use. Examples are caffeine, acetaminophen, anti-seizure medication, and a recent discovery Dr. Spoelstra and his team have found to be incredibly effective: artificial sweeteners. Think about it: they are in everything from fruit snacks to ketchup to toothpaste and mouthwash. In his latest research, he needed to investigate the source of a surplus of nitrogen in a community's soil. Artificial sweeteners in rural wells and river seeps pointed to a wastewater problem.

| Iron Layers in Golf Course Soils with Glen Obear | 13 Jun 2018 | 00:31:53 | |
Rapid soil formation in engineered soils, as highlighted in the article "Soil Evolution Par for the Golf Course" with Glen Obear. Not all of us who go golfing think about what is happening underneath the green. Glen Obear has always been that kind of guy. Since his high school days, he has wanted to be a golf course superintendent – even though he doesn't play that much golf! What fascinates him is the science of developing a golf course. We may simply see a beautiful, natural-looking terrain, but those rolling hills and magnificent green fields are the product of the hard work of agronomists, soil scientists, and engineers. They manipulate the elements of soil creation to create a terrain that is perfectly suited to its purpose – an engineered soil. Engineered soils are everywhere – from an urban garden bed to athletic fields to green roofs. Glen's internship work at a golf course in Hawaii led him to find an interesting problem that not even his agronomy professors could solve. Iron pan layers called placic layers were developing in the greens between the sand and gravel layers. These layers were preventing the greens from draining water. However, there was little prior literature on these layers developing in engineered soils. He's now focused his PhD research on these placic layers. Listen in to learn to hear Glen discuss more of his research on engineered soils and to learn:

| Blue Carbon in Mangrove Forests with Dr. Gabriel Nuto Nóbrega | 13 Jun 2018 | 00:28:15 | |
"Diffuse Reflectance Spectroscopy (Vis-Nir-Swir) as a Promising Tool for Blue Carbon Quantification in Mangrove Soils: A Case of Study in Tropical Semiarid Climatic Conditions" with Dr. Gabriel Nuto Nóbrega. Mangrove forests are some of the most important forests in the world. Mangroves are uniquely adapted to acting as a middleman. They can deal with very high salinity and hide tides, but when the tide drops, they can deal with the low salinity. They act as nurseries for young birds, fish, and large, rare mammals like dugongs and manatees before they are ready to branch out into the ocean. They also have the important ability to act as a carbon sink – they take carbon from the atmosphere and trap it in the soils. Dr. Gabriel Nuto Nóbrega has been working with this aspect of mangrove soils since his undergrad days. He wanted to know just how much carbon mangrove forests have the capability to sequester. However, the act of doing so had proven tricky. Not only were traditional methods not reliably measuring the carbon, but they were leaving a toxic residue behind – not ideal in an important and sensitive ecosystem. His solution was DRS – diffusive reflectance spectroscopy, a technique that is not only friendlier to the ecosystem, but cheaper and easier than traditional methods. Listen in to learn about:

| Antibiotic Resistance in Nebraskan Soils with Dr. Lisa Durso | 13 Jun 2018 | 00:28:47 | |
"Assessment of Selected Antibiotic Resistances in Ungrazed Native Nebraska Prairie Soils" with Dr. Lisa Durso. Antibiotic resistance has revealed itself as one of the great public health threats of our lifetimes. It currently causes 23,000 deaths per year and $55 billion of health costs in the U.S. Those numbers are predicted to skyrocket in coming years without major change. However, there's a caveat that makes researching it harder. Antibiotic resistance occurs naturally in soil, even without antibiotics present – but we're not sure why. That's where Dr. Lisa Durso comes in. She works with the USDA-ARS to look at Nebraskan soils and examine how much antibiotic resistance really occurs in untouched soil so we can establish a baseline for future research. She works with native prairie soils all over Nebraska to promote the broader goal of learning how drug-resistant genes survive in environments, and how they can move from field to people.

| Cover Crop Cocktails with Dr. Ebony Murrell and Dr. Mac Burgess | 13 Jun 2018 | 00:35:17 | |
"Achieving Diverse Cover Crop Mixtures: Effects of Planting Date and Seeding Rate" with Dr. Ebony Murrell and Dr. Mac Burgess In fall, organic farmers across the country will start spreading seeds for crops that they won't ever harvest. The reason? They're cover crops! The secret agents of the crop game, these are crops that are planted in between plantings of cash crops like corn or wheat because of their many benefits to the land, the environment, and the farmer. Historically, they've been planted to prevent water from carrying nutrients away in runoff. But in recent years, there have been discoveries of the many other benefits that cover crops provide, everything from weed suppression, to breaking up soil compaction, to making more nutrients like nitrogen available to their crops in spring. Dr. Ebony Murrell and Dr. Mac Burgess are fascinated with all of this. They've found that mixing cover crops together can bring those benefits to the next level, especially if they are equally represented in the spring. Working with a panel of farmers, agronomic industry professionals, and academics, the two developed four seed mixes that brought together some of the most popular cover crops to see how these pairs worked with one another and how each was represented in spring.

"Mixing things up! Identifying early diversity benefits and facilitating the development of improved variety mixtures with high throughput field phenotyping" with Flavian Tschurr and Corina Oppliger. With increasing yield instability in monocropping systems due to diseases, pests or climatic factors, crop diversification is a potential strategy to improve crop performance and yield stability. However, crop diversification can present challenges in agronomic management and operations. One promising approach to crop diversification is using multiple varieties of one crop rather than multiple species. However, challenges remain in selecting suitable crop varieties and determining their optimum mixture rates. In this episode, graduate students Flavian Tschurr and Corina Oppliger share their insights on using image-based high-throughput phenotyping to optimize crop variety mixtures. Tune in to learn: · What is a crop variety mixture? · What are the benefits of crop variety mixture? · What is the use of high throughput phenotyping in crop improvement? · What is crop over-yielding?

| Flyway Flooding Impacts with Dr. Amitava Chatterjee | 16 Aug 2024 | 00:39:45 | |
"Shallow water habitat management influences soil CO2 efflux from agricultural fields in the Lower Mississippi River Basin (LMRB), USA" with Amitava Chatterjee. The Lower Mississippi River Basin (LMRB) serves as a critical stopover habitat for migratory birds traveling between Canada and Central and South America, presenting both challenges and opportunities for habitat conservation. To support these birds, farmers in the region flood agricultural fields in the winter, creating temporary wetlands that provide habitat and essential food sources. This practice has increased bird stopovers but raises concerns about soil health, as flooding can alter soil properties. In this episode, Dr. Amitava Chatterjee shares his insights on research related to the effects of flooding on soil properties in agricultural lands in the LMRB and how it contributes to maintaining sustainable stopover habitats for migratory birds. Tune in to learn: · What migratory bird stopovers are · How flooding of agricultural lands helps migratory birds · How flooding of agricultural land affects soil health · How flooding affects soil microbial activity · What are the long-term impacts of agricultural land flooding If you would like more information about this topic, this episode's paper is available here: https://doi.org/10.1002/agg2.20365 This paper is always freely available.

| Leaf Mold Compost for Urban Agriculture with Kyle Richardville | 19 Jul 2024 | 00:35:56 | |
"Leaf mold compost for better soil and crop health" with Kyle Richardville Growing vegetables in urban gardens is becoming a popular and ever more important option for supporting families with nutritious and healthy produce. However, the use of chemical fertilizers and pesticides can cause negative impacts on soil, crop, and human health. To reduce these negative impacts, there is a growing interest in using biologicals and compost manure for crop production. This episode, Kyle Richardville, agronomist and regenerative agriculture consultant at "Understanding Ag," shares his insights on the importance of a compost made from tree leaves and fungi—leaf mold compost—and how it impacts soil microbial communities, soil physical properties, and overall crop production. Tune in to learn: · What are biologicals and compost manure? · What is Trichoderma and how does it help in agriculture? · How do mycorrhizal fungi benefit plants? · How does compost manure increase soil and crop health?

| Genomic Selection with Dr. Jianming Yu | 17 Oct 2025 | 00:33:17 | |
"Genomic Selection: Essence, Applications, and Prospects" with Dr. Jianming Yu Genomic Selection is a plant breeding innovation that aims to speed plant breeding by using predictions from a training model enabled by genomics and statistics to guide the breeding decisions. With around thirty years of history around this innovation, it was about time to develop a review on it. Enter Dr. Jianming Yu and his team of coauthors. This episode, we skate the surface of a topic that could go down for miles, covering key areas of genomic selection, what it is, how to use it, and where we can aim to go in the future. Tune in to learn: · How genomic selection was developed · Why genomic selection should be seen as an innovation in rather than alternative to plant breeding · Why growing out crosses still matters · How AI could be integrated to further genomic selection If you would like more information about this topic, this episode's paper is available here: https://doi.org/10.1002/tpg2.70053 This paper is always freely available.
