Photograph of a six year old Switchgrass in bloom. Note bare ground near clump where sand Lovegrass has been eliminated.

Photograph of land seeded to sand Lovegrass in 1945 and over seeded to bluestem mixture in 1950. Note elimination of sand Lovegrass in competition with other grasses.

Photograph of some excellent specimens of bluestem. Sand bluestem on the left and little bluestem on right. Note sand Lovegrass adjacent. Pasture was grazed all during 1955 but not heavily. Good vigor of grass in 1956 at watering place. Bluestem plants six years old.

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.
