"United States soybean seed protein concentrations – current status, challenges and some potential crop management solutions" with Dr. Anuj Chiluwal.

Soybeans are a crucial crop in the United States for a variety of uses, including for its use as a protein source in animal feed. However, in recent years, high yield varieties have seen a steady decline in seed protein concentration. In this episode, Anuj joins me to discuss the sources of this decline and some potential strategies to combat it.

Tune in to learn:

· Why soybean seed protein is declining in US soybean

· How the US may be a template for other countries with similar problems

· What temporary solutions may be available for this problem

· Which future research paths may bring about more sustainable solutions

"Using electromagnetic induction to inform precision turfgrass management strategies in sand-capped golf course fairways" with Dr. Briana Wyatt and Dallas Williams

Golf courses are well known for their beautiful greens, but overusing fertilizer and water to keep them looking pristine can lead to inefficient, expensive, and environmentally damaging waste. Precision turfgrass management can help, but only if we can find the right methods to put it into use. In this episode, Briana and Dallas join me to discuss their research on how electrical conductivity can be used to help determine golf course needs.

Tune in to learn:

· How many management zones might be in a fairway

· How turfgrass type can effect electromagnetic induction correlations

"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?

"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.

Tune in to learn:

• What is mixed cropping?
• What makes a farm machine "autonomous"?
• How do autonomous machines contribute to environmentally friendly agriculture?
• What are the economic differences between automated strip farming and conventional strip farming?
• What are swarm robots in agriculture?

"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?
