“…The results of studies reported by Stauffer et al (4) indicate that intensive cropping reduces the organic matter and degree of aggregation in the surface soil. Since the soil type studied by these investigators was the same as that shown in figure 2 and table 1, the organic carbon determinations and aggregate analysis should be generally applicable to similar management practices reported in this section of the present paper.…”

The purpose of this study was to determine some of the changes that have taken place in the structure of several Corn Belt soils and its influence on tilth, permeability, volume weight, and percent of pores drained. Samples of soil were examined in the field to determine the type, class, and grade of structure, direction of natural fracture when lumps were broken, and size and number of visible pores. Six to twelve undisturbed soil core samples 3 inches thick and 3 inches in diameter were taken at random from each plot and depth to determine permeability, volume weight, and percent of pores drained at 60 centimeters tension. Many surface soils that originally were granular or crumb in structure have changed through cultivation and poor management practices to a fine fragmental or massive structure. With these changes in structure the percolation rate decreased from 8.4 inches to 0.2 of an inch per hour, percent of pores drained was reduced from 9.2 to 3.5, and the volume weight increased from 1.1 to 1.31. The surface crust was the least permeable layer in the upper 18 inches of the soils studied.

“…The Morrow plots at the University of Illinois were established in 1876 to study the yield effects of crop rotations and fertilization (Table 3). Crop sequences (in a single replication) were: continuous corn, corn-oats, and corn-oats-clover, with and without added manure, lime, and rock phosphate (Stauffer, et al , 1940). At the Morrow plots the results show that continuous corn plots with no fertilizer decreased soil organic matter (SOM) content by 45.6% in 55 years as compared with the adjacent sod.…”
