Study of Soil Available Nutrient Spatial Variability

The spatial variability of soil nutrients in corn field of Luopu county Dulu town Halapu village using classical statistics method and geostatistics methods. Results showed that the soil available nutrient is middling variability, it become from 18% to 33%. Using geostatistics methods analysis spatial variability, evince that soil available om?totalN?N have relativity. C 0/C 0+C is 9.2%～18.9%, it showed that spatial variability cause by matrix of soil?topography?climate and so on, P?K have middling relativity, C 0/C 0+C is 50.7%?44.8%, it show that spatial variability cause by fertilizer?crop and level of manage.
