Nitrogen may be one of the most mysterious nutrients that we deal with in agriculture. The dynamic elements of the nitrogen cycle make nitrogen quite a fickle nutrient in our systems. In this episode, we are joined by Dr. Richard Mulvaney of the University of Illinois to discuss how Soil Organic Matter and Microbial activity drive N availability to our crops. We also discuss the question, are we applying too much chemical N?
