Photograph of gully control. Gully controlled by just putting stalks of Darso [a type of sorghum] in the gully, butting toward the head of the gully, and throwing a few shovels of dirt over the upper ends. Silting has taken place and vegetation has come in and the gully is now quite stabilized. OK-5336.

Photograph of hairy vetch growing on submarginal land only a few inches thick above bedrock. The vetch was used as a winter cover crop and will be plowed under as green manure. Gullies can be seen in the field above in which [unclear] is exposed. OK-5710.

Photograph of grasses. Weeping Love Grass (Eragrostis cruvula) in a cultivation study. Note the rows to the right of the white stick and the broadcast to the left of this. The area was seeded in April, 1939, on Chickasha fine sandy loam soil. # 340.

Photograph of brush control by chemicals. Where selective chemicals are properly used the land cover is not destroyed and erosion is controlled. Leaves, twigs and stems of Black-jack and other oak brush is sprayed with a mixture of 2,4-D and 2,4,5-T herbicide all accumulated in a mulch on the soil. There was an average of 7,593 pounds per acre of litter two years after the treatment. This mulch conserves the water and makes conditions ideal for the growth of grass. The area on the left was not treated while the area on the right was. The grass is more effective for erosion and flood control than the original cover of brush and grass. There was a 45% reduction in water run off annually from good grass on the altered land than from the adjacent area of brushland. OK-79, 441.
