Episode #40: Cutting the Nitrogen Bill with Legumes and Microbes

Nitrogen fertilizer costs U.S. farmers $5 billion a year — but a good chunk of it is sitting in the atmosphere for free. Zach Lauck joins Keith to break down which legumes actually pull their weight (hairy vetch, winter peas, clovers), why timing and planting depth make or break them, and how new inoculants and free-living microbes can fix nitrogen even without a legume in the mix. If you're looking to cut input costs without cutting corners, this one's for you.
