Dr. Marshall McDaniels – Using Tea Bags to Assess Soil – PFI 2018 Annual Conference

Dr. Marshall McDaniels, assistant soil science professor in the agronomy department at Iowa State University, presents some preliminary data from a 2017 study using decomposition of common types of tea as an inexpensive, yet scientifically robust way to measure soil health. This study included over a dozen PFI farms across Iowa. He presents major trends across soil types and management treatments, and also whether the tea decomposition seems to be a good indicator of soil health.
