Abstract: Observing points by grid were made in field 450000 m2 and adopted method of GPS orientation .Soil samples were obtained under land of 0~20cm. N, P, K and Organic matter were measured in laboratory. Soil variability was studied with routine statistics method and spatial analysis method. The result showed that there existed spatial variability of soil nutrients. N, P and K had medium variability, which were mainly affected by routine fertilization measures. On the contrary, Organic matter has a smaller spatial variability; Soil nutrient had semi-variance structure, and model best fit included Circular, Pentaspherical and Exponential. There existed medium spatial correlation in N, P, K and OM.
