Our three guests this week just finished a SARE grant project looking at using urine as a fertilizer. Tatiana Schreiber and Abe Noe-Hays are from the Rich Earth Institute, and Deborah Aller is at Cornell University, and on this week’s podcast they tell us what they learned looking at the soil health impacts and farmer perspectives on using various forms of human waste and control treatments for fertilizer. They tell us what products they used, how farmers can make use of them, and how this technology might be scaled up in the future.
