摘要：

On U.S. cropland, the use of cover crops increased by 50 percent between 2012 and 2017. Over this same period, Federal and State conservation programs have increased efforts to promote cover crops through financial and technical assistance. Based on a series of farm- and field-level surveys, this report details how cover crops are managed on corn, cotton, soybean, and wheat fields.
