Effect of cover crops on weed biomass and density in the US Midwest Corn Belt meta-analysis dataset

This dataset contains paired measurements of weed biomass and/or weed density taken in a control corn/soybean rotation and the same rotation with a winter cover crop. The data was pulled from 15 published studies that took place within one of the 12 top corn-producing states in the US, which make up the Midwestern Corn Belt.
