The Nitrogen Value of Cover Crops with Dr. Guillermo Marcillo

“The Nitrogen Value of Cover Crops” with Dr. Guillermo Marcillo. Cover crops are known for their ability to provide economic and ecosystem services to farmers, including, for example, impacting soil nitrogen. But how much nitrogen, exactly, can cover crops add or remove and how do we find out? In this episode, Guillermo joins me to discuss his work collating research data to get to the bottom of cover crop nitrogen replacement values. Tune in to learn: ·         What a nitrogen replacement value is ·         Why negative nitrogen replacement values are sometimes a positive ·         Which cover crops have, generally, which nitrogen replacement values ·         How nitrogen replacement values can be reverse engineered from existing data If you would like more information about this topic, this episode’s paper is available here: https://doi.org/10.1002/ael2.70006 This paper is always freely available.
