Photograph of brush control. Follow-up from OK-633-2 (August 4, 1958). On the east side is a cement culvert. OK-1000-2.

Photograph of grasses. Native grass planting in the spring, 1959. Pure blue grama side by side with complete native grass mixture. Planting occurred this way due to the failure to mix the seed. OK-1001-3.

Photograph of grasses. Native grass planting. Follow up of OK-632-7, August 4, 1958.

Photograph of grasses. Native grass planting. Follow-up of OK-488-1, May 15, 1957. OK-1001-2.

Photograph of Carey silt loam profile. Note the compound columnar structure and the accumulation of caliche. The A1 horizon is about 12 inches thick, the B2 and B3 are about 2 ½ feet thick and the C ca [ca = pedogenic carbonates = carbonic acids that can that modify soil constituents] horizon extend below this. Entire picture covers 6½ feet of depth, typical of much of Carey soils in Harper County, transported by alluvial-colluvial forces from nearby hills and a weak B horizon has formed in places. Some soils are moderately permeable. OK-304-4.

Photograph of crop residue utilization. Excellent wheat on 70 soil.** Mr. Jude Matli, as SCD Cooperator, manages his crop residue to prevent sol loss by wind and water erosion by leaving a maximum amount of straw on the surface. He uses a combination of methods to control weeds and prepare a seedbed based on conditions of flexible tillage. His soil management program also includes a legume of vetch, sweetclover or alfalfa. OK-279-8. ** 70 soil. Unclear on the term. Perhaps referring to a 70/30 soil mix (= 70% topsoil plus 30% composting materials) or a heads or tillage per square foot number (https://extension.okstate.edu/fact-sheets/estimating-wheat-grain-yield-potential-2.html)
