Photograph of strip crops and cover crops on contour for wind and water erosion control. Rye cover crop was seeded immediately after peanuts were dug. Crotalaria in 4 rows, peanuts in 8 rows. Mr. Whit Sides says that the crotalaria prevents soil from blowing after the peanut harvest while also fixing nitrogen and humus to the soil. Where peanuts have already been harvested this year, Mr. Sides says he made from 2 to 3 bushels more per acre from the old crotalaria strips than he did on land where sorghum or other non-leguminous crops were planted last year.
