| Abstract: | Geestatistical analyst was used to study the spatial variability of soil nutrients in The Precision Agriculture Hardcore Demonstration Plot of Jilin Province. The results showed that there existed medium spatial correlation in N, P, K and organic matter. There existed spatial variability of soil nutrient. P and OM had medium variability, N and K has a smaller spatial variability. The range of P was bigger. On the contrary, the range of OM was smaller. |
