in North America have been using Cover Crops in vineyards
and orchards since the early 1900s. For the most part they
planted winter annual grains and legumes in hopes of
reducing erosion, improving soil tilth and water
penetration, and also adding nitrogen.
However, farmers strayed from cover cropping in the mid to
late 1940s with an insurgence of synthetic fertilizers
entering the market. It wasn’t until the late 1980s that
farmers again began to adopt the age-old practice of cover
cropping. This was due to a growing interest in sustainable
agriculture as well as new cover cropping techniques.
