- Eighty-five cooperative fertilizer experiments on cotton were conducted with farmers on the soils in the Blackland Prairie of Texas in 1930, 1931, and 1932, to determine the effect of fertilizers on the yield of cotton and on the control of the root-rot disease of cotton. In these experiments the 4-8-4, 4-8-0, and 6-12-0 fertilizers produced significant increases in yield of cotton, but the increases were not profitable. The fertilizer treatments had no effect on the root-rot disease. These results indicate that on the soils studied the use of fertilizers is not a promising means of reducing or evading the losses caused by the disease.
