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.
