Abstract

 Salinization and sodification of soils is one of the major problems in arid and semi-arid regions with shallow water table. Preparing SOIL SALINITY map for site-specific management is an important issue, since excess of soluble salts in the soils root zone can provide problems to the plant growth. Study area is located in the northeast of AQ-QALA. For preparing SOIL SALINITY map, samples of 100m*100m grid pattern in 784 points from 0-30 cm soil depth were taken. Electrical conductivity from soil saturation extract (ECe) was measured. Analysis of data and preparing ECE MAP were carried using a Geographic Information System (GIS). The results were indicated that, ECe of study area is 9-32 dSm-1. According to the SOIL SALINITY map, soils were classified in the three ranges: 9-15, 15-24 and 24-32 dSm-1. The results were indicated that the soils of study area were affected by salinization and sodification due to excessive evaporation of shallow saline water-table. While, soils in southlands is the more salinity than northlands, due to shallower water-table. Therefore, site-specific management and increasing the water table depth in study area suggested as main method to prevent of soil salinization and sodification. In this study preparing SOIL SALINITY map was aim for site-specific management and reclamation of soils in study area.
