Study on the Spatial Variability of Soil nutrient in the Field

Shujuan Zhang

Abstract

63 sample points of soil nutrient,oriented by GPS receiver were collected on a 50 m grid in the field of a winter wheat in Taigu. Soil nutrient data of each sample point was measured by chemical method. Spatial distribution maps of soil nutrient were drawn and analyzed by using spatial analyst model of ArcView3.3 software. The analysis results would provide reference for precise fertilization management.
