Multiple Regression Analysis Of Soil Properties On Eroded And Native Deep Loess Missouri Soils, S. J. Indorante, J. M. Maatta, R. D. Hammer, J. R. Brown

Conference on Applied Statistics in Agriculture

Researchers have described the difficulty of studying the effects of cultivation on soil properties unless native (uncultivated) areas can be used as a baseline for comparison. Even when suitable areas are located the problems of quantifying and comparing the horizontal and vertical distributions of soil properties remain. Areal distributions of soil surface, subsurface, and upper subsoil properties were compared in cultivated and forested deep loess soils on similar geomorphic surfaces and hillslope positions in two counties adjacent to the Missouri River. A 3-dimensional grid was used to sample selected soils from the summit to the lower backs lope on 3 …
