In this episode of Voices from the Field, NCAT Agriculture Specialists Nina Prater, Darron Gaus, and Lee Rinehart continue their exploration of plant nutrients. In previous episodes, they covered nitrogen, phosphorus, potassium, and calcium, and in this episode they dive into the pungent world of sulfur. They discuss the history of sulfur, how sulfur is related to air quality, how sulfur works in the soil, why it is so important in plants, and how to manage sulfur in sustainable and organic ways.
