Abstract

Amount of MICRONUTRITION ELEMENTS in agricultural soils is one of the most important properties in crops production. Most Better management of these elements in broad sense requires that their maps be produced in the study area. One of the most important tools for providing these kinds of maps is geostatistics. In the study, the efficiencies of four methods including weighted moving average, spline, ordinary kriging, and co-kriging in interpolating four elements of iron, zinc, boron, and cobalt were investigated. After investigating variograms and running these methods results showed that for interpolating iron, zinc, boron, and cobalt the co-kriging method was the best. Also results of INTERPOLATIONs revealed that iron had the lowest INTERPOLATION error (MAE=0.353 and RMSE=0.661). Then, based on the co-kriging method ZONING maps of these elements were prepared for Hamadan province. Based on the created maps shortage of micro-nutrition elements was observed in Northern parts of the province. Therefore, in order to obviate this shortage and attain sustainable agriculture in this region, using micro complete fertilizers is offered.
