Effects of Long-Time Soil Treatments on the Organic Carbon Content of Some Illinois Soils1

Synopsis

Synopsis

The organic carbon content of 8 soil types on 7 Illinois soil-experiment fields was relatively little affected by 40 years, of different fertility treatments, although crop yields were increased markedly by the treatments. Three treatments, (1) manure, lime, and rock phosphate, (2) no lime or fertilizer, and (3) residues, lime, rock phosphate, and potash, were included in the study.
