Research on Spatial Variability of Soil Nutrients In the Mu Us Sandland
In this paper,the data of the soil total N,P and K used in this study are collected from the Wushen Mu Us Desert in the 0~40 cm of the soil,on the basis the traditional classical theory of probability and statistical theory,and three kinds of spatial distribution of soil nutrients are shown,the maps of variogram and spatial distribution of the three soil distribution regular patterns of soil nutrients are drawn.Nutrients are analyzed,which comes in three kinds of spatial distribution,the content of the soil total N,P and K are very small,they belong to six,relatively poor soil nutrients.By sampling and analyzing the soil,we conclude that the distribution and spatial variation of the soil nutrients in the research area,for the promotion and increase in the Mu Us Sandland of agricultural production,it serves as a theoretical and scientific reference for the accurate guidance of agricultural production.
