Abstract

Paired moderately and severely eroded phases of Clarence (Aquic Argiudolls), Grantsburg (Typic Fragiudalfs), Hoyleton (Aquollic Hapludalfs), Rozetta (Typic Hapludalfs), and Tama (Typic Argiudolls) soils were included. Five-year Zea mays yield averages for plots of Rozetta and Tama soils with favorable sub-soils for rooting showed nonsignificant differences between moderately and severely eroded plots. Yield averages for the plots on severely eroded Clarence, Grantsburg, and Hoyleton soils with root-restricting subsoils declined 16-35% from yields obtained on corresponding moderately eroded phases of these soils. Significant plant population reductions occurred only on plots of severely eroded phases of fine-textured Clarence and Hoyleton soils. -from Authors
