Cover cropping was extensively used around the country in the first half of the 20th century. With the development of selective pre-and post-emergent herbicides, many farmers transitioned away from growing cover crops in the 1950s. In recent years the increased focus on soil quality and reducing chemical inputs has led to a renewed interest in the potential benefits of including cover crops in an agricultural production system.  1, record 3, English, - cover%20cropping
