Abstract

Soil conservation and optimal productivity need to more knowledge and awareness from all interfering agents which are involved in using of soil to appropriate plant nutrition, yield increasing and agricultural products quality. At present, excess fertilizer use has been led to increasing soil salinity irrespective to soil solution materials. In order to reduce this effect and fertilizers sustainable management, It is necessary to provide informative maps that show fertilizer distribution pattern. For this purpose, a field sampling was carried out and 52 points were coordinated by GPS. Related measurements of Soil EC were done and the values were interpolated by Inverse Distance Weighted (IDW) and Spline (SP) methods by using digital elevation model and raster spatial analysis procedures. The thresholds of EC to 50% of yield and EC response threshold were used to classify the filed as appropriate and inappropriate zones. This was done for 54 different plants (including cereals, industrial crops, vegetables, trees and shrubs) and appropriate zones for each plant was determined. This can be useful to determine reasonable cropping and rotation patterns to manage EC as a deteriorate factor on soil. More EC can impose soils to degradation during the time and appropriate cropping patterns, especially selection of plants could be useful to alleviate soil erosion and degradation. These reclassified maps could be useful to clarify the ways of optimized use of soil in respect to salinity challenge
