Soil Health Partnership reviews the August 2020 Iowa derecho, which damaged about 3.57 million acres of corn and 2.5 million acres of soybeans. Estimates put grain losses at 200 to 400 million bushels and storage damage at about 100 million bushels.
The article focuses on lessons about crop insurance coverage.
The 2020 derecho losses were already reflected in the 2020 crop and stocks. The article is about insurance planning, so it has little direct price effect.
