“…In heavy-textured soil, application of gypsum is more appropriated to hasten the process of reclamation in comparison to light-textured soil (Khosla et al, 1979). Gypsum plays a significant role in the reclamation of saline-sodic soils by providing a Ca 2+ cation to replace the exchangeable Na + from the colloid's cation exchange positions and leaching it out from the root zone into groundwater (Ilyas et al, 1997;Sharma & Minhas, 2005).…”

Saline-sodic soil is considered as a serious problem which could negatively affect rice water use efficiency, plant growth, and yield. Therefore, the objective of the current study was to investigate the effects of gypsum applied before sowing (i.e. gypsum and without gypsum) and irrigation interval treatments applied after anthesis (irrigation every 4, 6, 8 days) on chemical characterizations of clay saline-sodic soil. In addition, the effect of these treatments on rice growth, water use efficiency and related parameters and yield were investigated. A significant higher efficiency in reclamation of clay saline-sodic soil was obtained in terms of reducing SAR, Na +

“…With more attention paid to the environment, people have realized the importance of recovery of the grassland, and have taken many measures towards reclamation. The traditional methods mainly included enclosure to exclude grazing (Verdoodt et al, 2010), tillage (Gilbert et al, 2003;Sadiq et al, 2007), and application of manure, gypsum and sand (Ilyas et al, 1997;Li et al, 2003). Planting P. tenuiflora by artificial sowing is an efficient way to recover grassland.…”

“…Many research works have documented the following positive effects of calcium sulfate applications on the physico-chemical properties of saline-sodic soils: increasing permeability and leaching (Baumhardt et al, 1992;Ilyas et al, 1997); increasing flocculation and soil macroporosity (Chartres et al, 1985;Greene et al, 1988) and reduction of surface crusting.…”

The results of a two-year research aiming to evaluate the effects of corrective treatments on two saline-sodic soils are reported. The trial was carried out in cylindrical pots (high 0.6 m and with a diameter of 0.4 m), provided with a bottom control device to collect drainage water, and located under shed, to avoid rain leaching effect. The two clay soils: Saline and saline-sodic resulting from a fouryear experiment in which different crops had been irrigated with 9 solutions obtained by dissolving in distilled water the appropriate amounts of NaCl and CaCl 2 by the factorial combination of three salt concentrations and three SAR levels (5, 15 and 45). During the subsequent two-year period, the soils were cropped to barley and borlotto bean and irrigated with freshwater (ECw = 0.5 dS m -1 and SAR = 0.45) whenever the soil contained in the pots lost by evapotranspiration 30% of the maximum available water (MAW). The corrective treatments were carried out by applying CaSO 4 to the soils with ESP>6% and leaching fractions equal to 20% of the watering volume to the most saline soils and proportionally lower fractions to the less saline soils, in order to reach, in the drainage water, electrical conductivity (EC) and sodium absorption ratio (SAR) values of 3 dS m -1 and 9, respectively. The reclamation treatments reduced significantly soil salinity and sodicity: Electrical conductivity of the saturation extract (ECe) decreased on average from 12.34 to 3.66 dS m -1 ; the exchangeable sodium percentage (ESP) dropped by 50.93 and 41.41% respectively for Bologna and Locorotondo soils.
