This study investigated soil quality under corn (Zea mays L.) -- soybean (Glycine max L.) rotation as affected by cereal rye (Secale cereal L.) cover crop in the U.S. Corn Belt. The objectives were to 1) examine the affect of cereal rye cover cropping on various physiochemical soil quality indicators, including bulk density and total porosity, plant available water content, soil organic carbon concentration and stock, total nitrogen concentrations and stock, pH, cation exchange capacity, and clay activity ratios to a depth of 60 cm; 2) integrate several of these soil surface (0---10 cm depth) quantitative parameters into a unit less soil quality index (SQI); and 3) examine the affect of cereal rye cover cropping on corn and soybean yields.three case studies were investigated with soil samples taken in 2011 and crop yields over four growing seasons. These case studies were on a Mollisol (Nicollet series: Fine-loamy, mixed, superactive, mesic Aquic Hapludoll) in northwestern Iowa, an Alfisol (Nabb series: Fine-silty, mixed, active, mesic Aquic Fragiudalf) in southeastern Indiana, and an Alfisol (Capac series: Fine-loamy, mixed active, mesic Aquic Glossudalf) in central Michigan.
