Soil phosphorus mapping using Kriging interpolation method

Establishing soil nutrient space data library and carrying out space variation analysis are premise and basis for carrying accurate agriculture forward. This thesis aims to link the requirement of National 863 Program to research and application of corn accurate operating system, apply GPS to collect massif information, combine GIS technology, process data, establish data library and draw maps, while applying Kriging value-inserting method to produce space variation diagram of soil phosphorus element. According to the analysis of space variation features of soil phosphorus in this region, we are to be provided with scientific basis on applying fertilizer properly, to carry out region-delimited management of nutrient and to guide presents in farming.
