The Agronomy Farm, located one mile east of Brookings, is representative of a large area of land in eastern South Dakota. It consists of 160 acres, of which about 130 acres are now laid out in various soil and crop experiments (Fig. 1). The soil, commonly called "loam" and classified as Barnes Loam, is in a good state of fertility. Results of the experiments on this farm will closely in dictate what may be expected from similar soil management, cropping systems and crop varieties on the same type of soil and under similar climatic conditions. Numerous experiments are now in progress on this farm. The information given in this circular represents a progress report only on those experiments for which results can now be evaluated. Further results will he published at intervals as the experiments progress.
