Spatial Variability of Plant Nutrients in Two Illinois Fields

Abstract

dc:description

The development of global positioning technology and variable rate fertilizer application equipment at the same time in which environmental and economic considerations guide many grower decisions concerning fertilizer application have raised old questions concerning the spatial variability of soil supplied plant nutrients in fields. Two Illinois fields which have been soil sampled in a 25 meter grid for several previous years and having a known history were selected to determine the variability of soil pH, and available P and K in a field environment.
