Abstract

This article covers the impact of different soil management practices on yield, and focuses on plant population and nitrogen (N) fertilizer management for corn planted on sloped soils. The relationship between A horizon (topsoil) thickness, corn population, and nitrogen fertilizer rate is summarized in Figures 1-3, respectively. These data are from a study by Kazemi, Dumenil, and Fenton in 1990 (Effects of accelerated erosion on corn yields of loess-derived and till-derived soils in Iowa, unpublished technical report, Department of Agronomy, Iowa State University).
