Abstract

Studies on the spatial variability of soil properties in forest stand scale are limited. In this study, we demonstrated spatial soil variability with use of GEOSTATISTIC technique in mixed beech FOREST SOIL. The main objectives were assessment of GEOSTATISTIC technique to improve efficiency soil study. Soil samples from 0 to 15 cm depth were collected within 120 locations, on a 50*50 m systematic randomized grid besides 15 transect basis over a 16 ha field. Spatial variability for soil pH and organic matter revealed anisotropic VARIOGRAM due to same range effect and sill. A GEOSTATISTICal analysis showed that the soil properties (pH, organic matter) were spatially structured. The nugget-to-sill ratio indicates a strong spatial dependence for soil pH, and a moderate spatial dependence for organic matter. Interpolation using KRIGING showed a spatial similarity among the soil properties. Soil pH increased in the northwest quadrant of the research area where located in footslope. The result of cross validation with use of MAE, MBE and MSE revealed that the high accuracy of estimation for soil acidity and organic matter.
