Photograph of cows grazing in Hairy Vetch that has been used as winter cover crop, soil builder, and later to be turned over as green manure.

Photograph of Boley Camp cooperative garden planted using contour farming methods by CCC workers. Contour farming: planting and cultivating crops around a hill rather than up and down the hill so the rows create a dam effect that slows water run-off. OK-5645.

Photograph of Elk City resevoir after a flood. It shows severe outting on backslope of dam. This dam overtopped its entire length before it broke.

Photograph of Perry Howell and son Dwight standing in a field of contour-drilled grain on an Oklahoma School land farm which is under a 5-year cooperative agreement with the Soil Conservation Service.

Photograph of mowing for wood control in a permanent alfalfa strip. Mowing is to help eliminate Johnson grass. To be followed by later pictures. OK-5724.

Photograph showing wind carrying silt onto a clean, cultivated field. Notice how the wind picks up the soil and carries it higher the further it travels. Also notice that the soil is not picked up until the wind has had a chance to gather momentum close to the ground. The soil in the foreground is not being carried as the end of the field is near, and the fence and vegetation act as a windbreak. This wind erosion is a serious problem in western Oklahoma, Kansas and southwestern Nebraska. OK-5123.

Photograph of a portion of the crowd at the Muskogee Field day held on May 28, 1937. The lunch, followed by speakers was held on top of Stebbins Mountain from which a comprehensive view of many phases of soil conservation was visible in the valley below. OK-5747.
