“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
