Abstract
The Wardha valley covers the districts of Wardha, Amravati and Yavatmal in the state of Maharashtra, India and the canal irrigation system has been commissioned recently. Earlier researchers mentioned that irrigation in black soils was deleterious to the properties of these soils. Therefore the study was undertaken to know the effect of canal irrigation system on physico-chemical properties of black soils in Wardha valley, Maharashtra. The soils were deep to very deep, calcareous, clayey, dark brown to very dark gray in colour and had well developed slickensides in subsurface horizons and classified as Vertisols. The soils are under perennial irrigation of medium salinity and low sodium water quality. Soils were moderate to strongly alkaline, nonsaline (ECe < 2 dSm-1) with high CEC (48 to 60 cmol (p+) kg-1) and base saturation (89 to 99 per cent). The ESP, EMP, Ca/Mg ratio and SAR ranged from 0.9 to 17.1 per cent, 20 to 49 per cent, 0.6 to 3.8 and 0.6 to 15.6, (cmol-1) respectively. Clay fraction dominated with smectite (41 to 67 per cent) along with Vermiculite, chlorite, mica, kaolinite, and feldspar. The presence of considerable amount of plagioclase feldspar was the source of sodium ions. Due to aridity of the climate, the soluble Ca2+ precipitated as CaCO3 increased the concentration of Mg2+ and Na2+ in the subsurface soil. Furthermore, because of injudicious irrigation the water table was raised and the upward movement of Na+ initiated in profile. The high smectitic clay, pH, CEC, ESP and SAR were responsible for high shrink-swell potential of these soils as COLE (0.17 to 0.27) and VSP (60.2 to 100 per cent) values falls in very high shrink-swell class and showed positive significant correlation. The high ESP, EMP, COLE and WDC impaired the drainage (HC 0.01 to 2.4 cm hr-1) which in turn waterlogged the soils. In order to optimize the production on sustainable basis improvement in natural drainage, applying suitable modification in land configuration, use of gypsum, proper selection of crops and far-spaced irrigation should be taken on priority basis.
