NPK stands for nitrogen phosphorus potassium. It's used on fertilizers when they're often sold with a rating for that. Where does it come from? Well, nitrogen now and fertilizers usually from the Haber-Bosch process are basically pulling it out of the atmosphere. They're converting it to a form that can become biologically available.
On this episode, Jason Bradford, who is an author, activist, farmer, and teacher, talks about the energy intensity of our modern industrial agriculture system.
How do we feed billions of people with depleting energy systems? How do we also protect existing biodiversity and ecosystem health? We also discuss what makes for healthy soil, why we’re losing it, and how small farms can help get it back - while creating higher yields of healthier foods for fewer inputs.

After graduate school he worked for the Center for Conservation and Sustainable Development at the Missouri Botanical Garden, was a Visiting Scholar at U.C. Davis, and during that period co-founded the Andes Biodiversity and Ecosystem Research Group (ABERG).
