  • Soybean Seed Protein Decline with Dr. Anuj Chiluwal
    Jun 20 2025
    “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 If you would like more information about this topic, this episode’s paper is available here: https://doi.org/10.1002/agj2.21731 This paper is always freely available.

  • Precision Turfgrass Management with Dr. Briana Wyatt and Dallas Williams
    May 16 2025

    “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

    · Which properties are most correlated with electromagnetic induction readings

    · How researchers can get readings on large areas of a golf course fairway

  • The Soil Health Cycle with Dr. Bijesh Maharjan
    Apr 18 2025

    “Soil Health Cycle” with Dr. Bijesh Maharjan

    Researchers, advisers, and farmers alike know that soil health is important, but taking steps forward in the knowledge of which practices to use and their impacts can be difficult. Enter the soil health cycle, an iterative approach to help track how practices and their implementation take soil health forward. In this episode, Bijesh joins me to discuss his work on the soil health cycle.

    Tune in to learn:

    · How the soil health cycle is similar to human health care cycles

    · What the four steps of the soil health cycle are

    · Why it’s important to have a soil health cycle

    · What the literature says about the current state of the soil health cycle

    If you would like more information about this topic, this episode’s paper is available here: https://doi.org/10.1002/agg2.20504
