green crop

After opening from pasture, two crops of oats; one of any green crop, as peas or beans in broad cast, or potatoes or turnips in drills, all with sufficient dunging; one of barley in broad cast, sown down with rye-grass and clover seeds ; two in hay, and four in pasture. This rotation is completed in ten years. Many leave out the green crop, which reduces the rotation to nine years.
