“Evaluation of speed breeding conditions for accelerating Fusarium head blight and deoxynivalenol screening in wheat” with Nidhi Rawat and Vivek Tiwari.   Fusarium head blight (FHB), also known as head scab, is one of the most significant diseases affecting wheat, causing substantial economic losses for farmers in the U.S. and worldwide. While FHB resistant wheat lines have been identified, breeding these traits into desirable cultivars is a time-consuming process that can take decades, with uncertain success. In the U.S., particularly for spring wheat, crossing of wheat lines can typically be done only once per year due to seasonal limitations, which slow down the process of development of disease-resistant cultivars. To overcome this challenge, speed breeding—an approach that involves growing plants under extended light exposure (20–22 hours per day) to accelerate their life cycle—offers a promising solution. This technique enables multiple generations of wheat to be produced within a single year, allowing for more frequent crossings and a faster transfer of disease resistance traits into desirable cultivars. In this episode, Drs. Nidhi Rawat and Vijay Tiwari share their insights on using speed breeding techniques to accelerate the breeding of disease-resistant cultivars. Tune in to learn: ·         What is Fusarium head blight? ·         How does Fusarium head blight cause economic loss to farmers? ·         What is speed breeding? ·         How does speed breeding help in developing disease resistance cultivars? ·         What are challenges in adopting speed breeding?

“Comparative productivity of six bioenergy cropping systems on marginal lands in the Great Lakes Region, USA” with Dileepa Jayawardena. Bioenergy crops present a promising source for biofuel production, offering a potential solution to reduce reliance on fossil fuels. However, they face criticism for potentially encroaching on arable land essential for food production to sustain growing populations. To address this issue, there is a growing focus on utilizing marginal lands for growing bioenergy crops, which are less suitable for crop production. Marginal lands typically suffer from poor soil health and low nutrient and water availability. Therefore, it is crucial to identify and develop bioenergy crops that can thrive in such conditions and produce biomass for biofuel production while also confirming which marginal lands are best suited to these uses.  In this episode, Dileepa Jayawardena, a Research Associate at The Great Lakes Bioenergy Research Center, Michigan State University, sheds light on his research aimed at finding suitable bioenergy cropping systems for marginal lands in Michigan and Wisconsin for producing biomass for long-term bioenergy production while minimizing the competition of land for food crops.  Tune in to learn more about ·         What are bioenergy crops? ·         What is the importance of bioenergy crops? ·         Why marginal lands can be suitable for bioenergy crops? ·         Which cropping system is better for marginal lands? ·         How to make sustainable biofuel production?

“Recalibrating the Pennsylvania pre-sidedress soil nitrate test recommendations for modern corn production” with Charles White. Nitrogen management is one of the most important agronomic practices in modern crop production systems. The Pre-Sidedress Soil Nitrate Test, also known as the PSNT, gives farmers an estimation of plant available nitrogen in the soil, allowing them to calculate how much nitrogen the plants still need. The existing PSNT method was developed during the 1990's. Now, farming practices are improved, altering the amount of nitrogen fertilizer plants need. Thus, it is important to re-calibrate the test so farmers can have a more accurate estimation of nitrogen requirements and reduce the cost of production.  In this episode, Dr. Charlie White shares his insights on re-calibrating the pre-side dress soil nitrate test for modern corn production systems. Tune in to learn more about: ·        What the Pre-Sidedress Soil Nitrate Test does ·        The importance of Nitrogen mineralization ·        Which improved practices have impacted the test's accuracy ·        Which factors most impact the test results now If you would like more information about this topic, this episode's paper is available here: https://doi.org/10.1002/agj2.21426 This paper is always freely available.

“Nitrogen mitigation scenarios to reduce coastal eutrophication” with Wafa and Patrick. Eutrophication is a state of overgrowth of aquatic plants, such as algae and seaweeds, in water bodies due to the excessive pouring of nutrients from different sources like agriculture, industry, and human settlements, causing disturbances to the ecosystems. Coastal eutrophication is a major issue worldwide due to the increasing discharge of nutrient emissions from agricultural activities into coastal ecosystems. Several efforts have been made to reduce eutrophication, achieving up to 35–40% reduction, but these measures are not sufficient to eliminate the problem. For more sustainable and effective solutions, the root causes of the nutrient emissions, especially nitrogen, need to be addressed in current agricultural practices. In this episode, Drs. Wafa Malik and Patrick Durand share their research on the reduction of coastal eutrophication in Brittany, France, focusing on changing cropping systems and reducing the sources through modeling the effectiveness of different approaches and taking into consideration the interests of farmers and the local community. Tune in to learn more about ·         How eutrophication happens ·         What are the causes and consequences of coastal eutrophication ·         What are the agricultural impacts of eutrophication ·         How we can change cropping systems to reduce eutrophication ·         What mitigation challenges exist in reducing coastal eutrophication If you would like more information about this topic, this episode's paper is available here:   https://doi.org/10.1002/agg2.20319 This paper is always freely available.

“Focusing the GWAS Lens on days to flower using latent variable phenotypes derived from global multienvironment trials” with Sandesh Neupane and Derek Wright. Lentil, a pivotal pulse crop, is recognized as an important part of food and nutrition security in the world. It has rich sources of important nutrients, is easy to cook, and thrives well on the farm. Due to its rich dietary benefits, lentil has been introduced to North America, especially in Canada. Originating as a warmer climate crop, domesticated in the Middle East and North Africa, and widely adopted in Southeast Asia, lentil can face adaptation issues in the cooler Canadian climate. This struggle directly impacts flowering, pod-bearing, and overall yield. What precisely are the adaptation constraints hindering lentil introduction in North America? How do varying photoperiods and temperatures exert influence on lentil production? Delving deeper, what genes govern the crop's sensitivity to photoperiods and temperatures? In this episode, Sandesh Neupane and Derek Wright share insights into their research on lentil adaptation and how they dissect the genetic mechanisms orchestrating the photoperiod and temperature sensitivity in lentils with multi-location trials and advanced image-based phenotyping. This groundbreaking work promises to contribute significantly to the breeding of well-suited lentil varieties tailored to thrive in North American conditions. Tune in to learn about: ·         Lentil and its nutritional value ·         Lentil's history ·         The challenges of lentil adaptation in Canada ·         How the environment affects lentil growth If you would like more information about this topic, this episode's paper is available here:  https://doi.org/10.1002/tpg2.20269 This paper is always freely available.

“Global Dependence Upon Corn Belt Dent Maize Germplasm: Challenges and Opportunities” with Dr. Stephen Smith, Affiliate Professor at Iowa State University Plant breeders are constantly trying to find the best crosses to increase the traits farmers and consumers want. However, continually crossing the same varieties can decrease the genetic gene pool over time, making plants susceptible to certain pests, diseases, and other stressors. To help understand the depth of the gene pool and to better understand how reliant we are on certain crop varieties, Dr. Stephen Smith and his team attempted to survey which maize varieties are bred and used the most. On this episode, we dive deep to discover what his team turned up. Tune in to learn: ·         What obstacles can exist for researchers trying to gather worldwide breeding data ·         Why pre-breeding is a crucial complement to the newest tech ·         Which countries keep the best maize breeding records ·         How reliant we are on certain maize varieties If you would like more information about this topic, this episode's paper is available here: https://doi.org/10.1002/csc2.20802 This paper is always freely available.

While we continue to hear of and experience the perils of global heating and climate disruption, some of us fundamentally understand that the ecosystem is not broken. Rather it is human connection to Nature that is in dire need of a correction. Or better stated, a re-connection. According to the World's Soil Resources Report from the UN of the top 10 threats to soil, soil erosion ranks number one, because it is happening globally. Although desertification intensifies at an alarming rate, and narratives of fear and scarcity dominate, the truth is human beings can restore our ecological memory, mimic and align with Nature, and commit to making the Earth green again. It remains the best kept secret that a regenerative mindset can and will heal the world. World-renowned soil scientist and conservation agronomist Ray Archuleta, Founder of Understanding Ag [https://understandingag.com] and the Soil Health Academy [https://soilhealthacademy.org/], joins us to tap his many decades of experience working with the soil to motivate us to green the Earth once again. Regeneration requires an understanding of relationships, a willingness to learn how Nature functions, and a shift in how and what we think. By adopting an ecological consciousness of Oneness, emulating Nature and applying Nature's principles to the soil, we can once again live a balanced, interdependent and harmonious life.

You might know soil remembers and has a long memory but do you know soils continually tell stories? Soils often tell an overarching story based on history and geology that includes how soils were formed due to factors such as parent material, climate, landscape position, time, and the presence or absence of soil organisms. Current and past management of topsoil and the soil ecosystem adds new chapters to a soil's history and memory. Clare Tallamy, a recent graduate of Virginia Tech's School of Plant and Environmental Sciences (SPES), shared several stories from her experience as a member of Virginia Tech's Soil Judging Team and the team's time in many different soil pits in Virginia and across the U.S. and world. In Part I, Clare described how a soil pit is dug and shared a way to understand a soil profile. In this episode, Clare explains further how soil remembers but also how a soil's story can be adversely altered through mismanagement and neglect or significantly improved by following core soil health principles that enhance overall soil biology and focus on what you can change in the system.For more details about Virginia Tech's Soil Judging Team and how soil judging in various agricultural and engineering contexts, please visit https://gobblerconnect.vt.edu/organization/soiljudging.
