This video is a formal description of a soil management experiment funded SARE. We were testing the theory that deficiencies of elements like zinc or sulfur in soil could manifest as deficiencies of the same elements in crops, which seems like it should be true. We compared conventional (as of the past 50 years) NPK fertilizing to an intense organic soil management routine that replaces a lot of trace elements in very precise amounts. What we found was surprising, except maybe to agricultural biochemists. Zinc and sulfur levels did not change, but some other metals did. Why?
