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.
