Photograph of the combination planting of oats and vetch in an apple orchard in Lowell, next to Highway #71. The back of the photograph proclaims, "Combination planting of vetch and oats in apple orchard. Cover crop has been cut into the soil with tractor and double disk to serve as a mulch in the orchard.
