Abstract:
The study was done in order to observe the effect of long-term use of sewage irrigation on chemical properties of soils viz. pH, EC, OM and CEC. Three sites of sewage irrigated soils of Prayagraj were these sites selected for the study Beligaon, Buxibhanth, Kulbhaskar Ashram PG College farm. The representative soil samples were collected from different depths 0-10, 10-20 and 20-30 cm. The sewage irrigated soil samples were analyzed in lab to determine the chemical properties of soils. The pH, EC, OM and CEC of sewage irrigated soils decreased with increasing soil depth up-to 7.09±0.21, 0.67±0.19 dSm-1, 1.02±0.12% and 19.92±0.79 Cmol (p+) kg-1 in 20-30 cm soil depth respectively. The EC, OM and CEC of sewage irrigated soils of all sewage irrigated selected sites were found as follows Beligaon 1.01±0.12 dSm-1, 1.10±0.16%, 20.86±0.74 Cmol (p+) kg-1 Kulbhaskar Ashram PG College farm 1.04±0.21 dSm-1, 1.03±0.11%, 20.17±0.76 Cmol(p+)kg-1 and Buxibandh 1.09±0.24 dSm-1, 1.10±0.14%, 22.22±0.95 Cmol (p+) kg-1 found more in comparison to sewage non-irrigated soils respectively but pH are less in sewage irrigated soils than non-irrigated soils are Beligaon 7.56±0.25, Kulbhaskar Ashram PG College farm 7.46±0.25, and Buxibandh 7.31±0.11. Thus, it may be concluded that sewage irrigated soils accumulated more organic matter and salts on surface layer and consequently decreased with increased soil depth. This Organic matter decomposed by various soil microorganisms and release of various organic acids. These organic acids lower down the soil pH. Finley the sewage water influence the chemical properties of soils.
