Photograph of lost water from straight row farming on about 2 percent slope section of land. Water was coming from field out into bar ditch in foreground along highway. Photograph was taken during a 1 in. rain.

Photograph of water lost from a field left of the photograph. The field was cultivated up and down slope. This stream of water came out of field into the bar ditch along highway during a 1.5 in. rainfall. Width of stream in foreground is 40 feet. Photo was taken while raining. Slope estimated to be 2 percent.

Photograph of a river of water pouring out of a section of land. Up and down slope tilled during a 1 1/4 inch of rain. Straight rows may be seen in background. The slope was about 2.5 inch toward the point where the picture was taken. The huge volume of water that broke through the end of the field into the bar ditch along highway caused regular rapids and churning water. Width of water in the main current was at least 2 feet deep. Photo was taken during a rain.

Photograph of hand harvesting weeping lovegrass seed in a 2-year old planting in a corner of a cultivated field. (Note terraces and contour cultivation in background). W.R. Whitehead operates a 520 acre farm and plans to plant 10 to 15 acres of lovegrass next year. Last year he hand harvested 24 lbs. of seed from 1/8th an acre. A 2 acre field of rye grass was grazed by 130 hogs, one hour in the morning and one hour in the afternoon for 90 days beginning February 1, 1945. Seed was then combined from the plot. Mr. Whitehead says the grazing alone was worth as much to him as 200 bushels of corn. Yield of lovegrass seed this year is estimated at 125 lbs per acre from approximately 8 acres. Mr. Whitehead and his son are shown in the photpgraph. OK-8992.

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 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 aerial view of watershed: OK-SCD-20 Wa #5, Site #3. Type of structure: Drop inlet. Drainage area: 160 acres. Soil units: Deep medium textured slowly permeable and permeable. Area in cultivation: 32 acres. Area in pasture: 12 acres. Area in abandoned cropland: 116 acres. General condition of drainage area: Poor cover, sheet and gully erosion. Note: Right edge shown Site #2 on Adolph Johanson farm. Type of structure: Drop inlet. Drainage area - 15 acres (4 acres in pasture, 11 acres in abandoned cropland). General condition of drainage area: Poor cover, serious gully & sheet erosion. It protects detention reservoir #1 & bottomland from silt. See pipe installed in third gully from right edge.
