The hydro chemical study reveals the quality of water and its suitability for agricultural purpose. Presence of excessive quantities of salts in groundwater is one of the major constrains in agro-well farming in Ganga-Sone Divide. Irrigation with poor quality waters may bring undesirable elements to the soil in excessive quantities affecting its fertility. Electrical conductivity (EC), sodium percentage (Na%), sodium adsorption ratio (SAR) and residual sodium carbonate (RSC) can be used as criteria for finding the suitability of irrigation waters. The objective of this study is to evaluate the suitability of the irrigation water quality of the Ganga-Sone divide region. Major cations, Na + , Ca 2+ , Mg 2+ , K + and major anions, Cl, SO 4 , HCO 3 , CO 3 were determined from 26 observation sites selected by CGWB located in Ganga-Sone divide region to assess the hazards of salinity, sodium and bicarbonate. Out of selected sites, based on EC, 46% of the wells have medium salinity water, 50% of the wells have high salinity water and 4% of the wells have very high salinity water. Based on percent of sodium, 69% of the wells have excellent irrigation water quality, 19% of the wells have good irrigation water quality, 4% of the wells have permissible irrigation water quality, 4% of the wells have doubtful irrigation water quality and 4% of the wells have unsuitable irrigation water quality. Based on SAR, almost all the wells have the good quality of irrigation water. Based on RSC, 100% of the wells have good irrigation water quality.
Agriculture is considered necessary to sustain life on this planet. With a growing population, we need agricultural productivity to increase significantly to meet the demands. Image processing has proven to be a powerful tool for analysis in many fields and applications. The agricultural sector, where parameters such as canopy cover, yield, and product quality were important for farmers. It is often the case that professional advice is not affordable, and that the availability of an expert and their services may take time. The situation could be greatly improved if image processing was combined with a reliable communication network, as this would eliminate the need to obtain expert advice within a limited time frame. This can be achieved because image processing is a powerful tool for parameter analysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
