Abstract

PADDY FIELDs have different status from fertility quality points of view. The quality of fertility and recognition of PADDY FIELDs potential are important and necessary with regard to the NUTRIENT ELEMENTS supply. This study was carried out to survey the SPATIAL VARIABILITY of soil properties and provide spatial distribution map of characteristics of soil fertility in 306 ha of Rice Research Institute of Iran. Measured soil physical and chemical properties were as follows: clay (C), silt (Si), sand (Sa), pH, Cation Exchange Capacity (CEC), Electrical Conductivity (EC), organic carbon (OC), total nitrogen (N), phosphorous (P) and potassium (K). Spatial distribution of the studied properties were evaluated by GEOSTATISTICS. The results showed that the studied soils inherent characteristics were related to soil fertility, despite the inherent differences in the spatial distribution were in the sufficient level. The available K had stronger spatial structure than other variables which could be an indication of the effect of parent material. Available phosphorous based on variation coefficient had the highest heterogeneity and medium spatial structure which reveals the effect of original and management factors on its behavior. Spatial distribution figure of nutrients shows the heterogeneity in spatial distribution of these elements and it is necessary to avoid uniform consumption of fertilizers in line with site specific nutrient management.
