(Location: IWMI-HQ Call no: 631.7.2 G232 SEL Record No: H0877)
A soil characterization survey of Abyuha was made at a sampling density of 1 profile per 20 feddans. The survey showed all soils to be in the Typic Torrerts great group of the Vertisol order, with no additional series or phase subdivisions. The surface horizons of all profiles were usually low in both salinity and sodicity. Both salinity and sodicity increased with depth. Maps have been drawn to show sampling locations, sodicity, and subsurface salinity. Tables of chemical and physical analyses are also included.

To reclaim saline-sodic soils, gypsum as inorganic, press mud as organic and kallar grass as biological material were compared in different combinations. Watertable was controlled by the installation of tile drainage. Gypsum at 50% requirement of soil, irrespective of its combination, proved more successful in reclamation of saline-sodic soils having ECe, pH, SAR and ESP values of 13.3, 8.8, 33.0 and 33.6 respectively with increase in yield of rice and berseem crops. Press mud and kallar grass also helped to lower the sodicity problem.

Experiments were conducted in wheat planted in microplots at Hisar and Sirsa in Haryana State, India, to observe and simulate the depth distribution of moisture content, electrical conductivity in 1:2 soil-water extract (EC 1:2), and exchangeable sodium percentage (ESP) of soils after irrigation with water of high electrical conductivity (12-19 dS/m) and sodium absorption ratio (20-80 (mmol/1)). The three simulation models used differed in the procedure of estimation of evapotranspiration (models I and II, Reddy 1983; model III Arora et al. 1987). In general, the means of the experimental moisture content profiles decreased and those of EC 1:2 and ESP increased with irrigation at both locations. Statistical analysis showed an overall good agreement between the experimental and simulated values of moisture content, EC 1:2 and ESP; the accuracy of simulation of the models followed the order model II=model III> model I, for moisture content and EC 1:2, but was identical for ESP.
