Abstract

One of the important soil properties, which is related to the soil-plant relationship, is Soil compaction. The aim of this study is to investigate the spatial variations of Soil compaction using different Geostatistic methods, affected by Conservation tillage. To evaluating the Geostatistic, soil samples were taken for regular grid of 10 × 10 meters in 117 points. The area of study was a 1. 2 hectare land in Agricultural Research Center located in the vicinity of Mashhad in Khorasan Razavi province, the soil cone index was measured at the depth of 0-35 cm. After Geostatistic analysis and semivariogram for estimating variables using the Kriging methods (EBK) and Deterministic Interpolation methods in GS + and Arc (GIS). Criteria for evaluation in this research are the values of root mean square error (RMSE), mean error (ME), using the cross-validation method. The results showed that the empirical Bayesian Kriging methods (EBK) and Ordinary Kriging (OK) are the best model to estimate Soil compaction region.
