Cover crops like White French millet can help improve ground cover and prevent soil erosion in farming. In a study, researchers found that planting cover crops before growing wheat can actually increase the amount of water available for the wheat to use. This means that the water used to grow the cover crops is effectively recovered, and the wheat crop benefits from the increased soil moisture. In a dry season, the wheat yield was higher with cover crops than without, showing that cover crops can be a beneficial practice for farmers in Northern grains production.
