Spatial variability of farmland soil nutrients is widely existent and very complex. As thenutrient sources of the plants, the soil’s nutrient variation definitely influences the growthvariation of the plants. The research on soil spatial variability, one of the soil features, provideseffective avenues for predictions and simulations of soil process, whereby the predicted results canbe more approximate to the real condition, and the importance of spatial effect, imposing on therelation between soil and plant...
