npHE physical change which a soil undergoes from a * virgin to cultivated state is of interest to agricultural workers in understanding the soil management problem. This problem is concerned not only with fertility but the physical properties which affect water intake, soil aeration, stability of aggregates, and others as well. Most of Iowa's prairie soils have been cultivated for 100 years or less. Changes that have occurred during this period may be a guide to the type of problems that soil scientists will face in the future in keeping the soil productive. Data by other investigators (3, 4, 6, 7, 8) show that in general, cultivation decreases the organic matter-content, the number of large size aggregates, the stability of the aggregates, the number of large pores and increases the susceptibility of the soil to erosion and the weight of the soil.
