  The present study aimed to assess the spatial variability and mapping of micronutrients under the sugarcane growing block of the Sivagangai district using geostatistics and the Geographic Information System (GIS). Totally, 100 georeferenced surface samples (0 cm-30 cm) were collected and analysed for soil physicochemical properties. Descriptive statistics showed that the variance values coefficient ranged from 7.32% to 49.83%. Geostatistical analysis was executed for mapping the soil fertility properties with aid of well-fitted semivariogram models. Through crossvalidation techniques, the Standardized Root Mean Square Error (RMSSE) was computed and utilized for good prediction of the model. Geostatistical analysis revealed exponential for pH, EC, free CaCO3 and B, circular model for OC and Zn, Spherical for Fe and Mn, and the Gaussian model fitted well for Cu. Multivariate .. View More»
