Abstract

Increasing land values have brought Iowa farmers to a realization of the importance of securing larger crop yields per acre. This has led to an insistent demand for information regarding soil needs and fertilizer treatments which will make them more profitably productive. The experimental work of the Soils Section of the Iowa Agricultural Experiment Station is planned to meet this demand and to show how larger crops may be grown on the soils of the state. As a direct outcome of this experimental work, the Iowa System of Soil Management has been developed. It is not a complicated, theoretical method of handling soils, but a simple, common sense, practical plan which provides for remedying those soil conditions which limit crop growth and make it impossible to secure the best possible yields.
