Reclamation of Saline-sodic Soils under Rice-wheat Crop Rotation
A field experiment on a saline-sodic soil with pH 8.21-8.42, ECe 6.40-7.90 dSm and SAR 17.79-23.46mmolwas carried out using five soil reclaiming treatments viz., leaching (Control), Farm yard manure (FYM) @ 10 tons ha, Rice Husk (RH) @ 10 tons ha, FYM+RH @ 5+5 tons ha and Gypsum @ 100% soil requirement in a complete randomized block design with four replications. Rice variety SARSHAR and wheat ...
متن کاملInvestigation of Leaching Process on Saline and Sodic Soils, and Provide a Suitable Experimental Model for Land Reform in “Southern Khuzestan” Soils
In regions like south of “ khouzestan” that water table are high, under the effect of water rise moving through capillary fringe and its vaporize, the salts move to soil surface and cause salin or salin and sodic soils. Leaching assign as one of those adjustment soils methods. In order to investigate the leaching process and draw the curves of desalinization and dealkalization in region of Dar...

متن کاملInvestigation of Leaching Requirement of Continuous and Alternate Ponding Methods in Saline and Sodic Soils in South of Khouzestan Province
In this study, leaching experiments were carried out by both continuous and alternate ponding methodsin the south of Khouzestan province. In equal applied water leaching, alternate ponding leachingmodel had a better performance than continuous ponding method in desalinization and dealkalization.In term of alternate method,there was not ayn difference between 5 and 8 day periods in one-meterdept...
متن کاملStability of a Calcareous Saline-Sodic Soil During Reclamation
General guidelines to reclaim saline or sodic soils do not adequately consider variables such as pH and the presence of organic matter that are known to affect soil stability. Poor structural stability of sodic, saline-sodic, and high-pH soils adversely influences crop yields; promotes piping, tunneling, and slope erosion; and can accelerate the failure of water conveyance systems. We evaluated...
