Effect of Adequate Nutrient Supply and Varying Conditions of Cultivation, Weed Control, and Moisture Supply on Soil Structure and Corn Yields1

C. L. W. Swanson and H. G. M. Jacobson2

Synopsis: Experimental data obtained over a 3-year period with field plots located on Cheshire sandy loam indicate that in humid climates under irrigated conditions with adequate fertilization, it is not necessary to clean cultivate to obtain maximum corn yields, provided the structure of the soil is maintained at an optimum. Under these conditions, one cultivation or use of herbicide may be adequate.

2 Chief Soil Scientist and Soil Scientist, respectively. Grateful acknowledgment is made to D. B. Downs and R. M. Hanna for assistance in the field and laboratory work.
