The Impact of Groundwater Salinity on the Quality of Agricultural Crops in Ishaqi Area Using GIS

Abstract

The study of the effect of groundwater salinity on the quality of agricultural crops in the Ishaqi area aims to identify the percentage of salts of groundwater in the region and to identify areas of high and low percentage as well as to determine the spatial distribution of groundwater abundance to be relied upon in determining the areas of distribution of different agricultural crops from Through the adoption of modern geographic technologies (GIS) to advance the reality of groundwater in the region and benefit from it in various investments by analyzing the hydrological characteristics of the groundwater spatially and its chemical analysis, studies have reached several The most important results:

• The diversity of agricultural crops, the diversity of water quality and the percentage of their salts.
• Increase in the number of wells in the area due to the lack of an irrigation project and the expansion of the area of cultivated land.
• The presence of variations in the proportions of salts and the concentrations of negative and positive ions, which in turn affected the difference in the type of crops grown in the region.
• The obvious variation of groundwater in the region in terms of density and numerical distribution affected by climatic fluctuations and other natural factors as well as the influence of human factors.
• The importance of using modern technologies in the study of groundwater through the analysis and conversion of raw spatial data into a digital database for the benefit of them in the analysis and preparation of hydrological models.
