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. TX-41, 815.

Photograph of a part of a 23 acre first year lovegrass seed increases planting on Class 1 land. Grass made a good stand in spite of Johnson grass competition. Three crops of Johnson grass were cut this year and lovegrass has just been cultivated. Seed will be sold to cooperators in the district. OK-8932.

Photograph of sorghum planted for non-competitive cover in preparation for seeding to side oats grama that will be drilled in the early spring [of 1945]. Sorghum was planted after harvesting small grains. Sideoats grama will be sown with native grass seed drilled in 36 inch rows and cultivated for seed production. Seed will be made available to co-operators in the Upper Washita Soil Conservation District. OK-8933.
