Plowing Under a Green Manure Crop
Description:
Photograph of Armin Groeneman, district cooperator, and neighbor, plowing under a green manure crop of four to six ton per acre of sweet clover. Land was limed six or seven years ago with 2. 5 tons per acre and 500 pounds of Raw Rock Phosphate per acre. Sweet clover in crop rotation is a common practice on the Groeneman farm. He says it opens the soil and allows better moisture penetration and improved crop yields.
