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 کاملGypsum Effect on the Aggregate Size and Geometry of Three Sodic Soils Under Reclamation
the soil particles and aggregates. Dispersion or flocculation of clays occurs because of the repulsion of similar Reclamation of sodic soils is imperative in many areas where detericharged clay platelets and the ability of the soil solution oration of land and water resources is in progress. While the chemical mechanisms involved in the reclamation of sodic soils are well deto mitigate this rep...
متن کاملSimulation and Prediction of Ion Transport in the Reclamation of Sodic Soils with Gypsum Based on the Support Vector Machine
The effect of gypsum on the physical and chemical characteristics of sodic soils is nonlinear and controlled by multiple factors. The support vector machine (SVM) is able to solve practical problems such as small samples, nonlinearity, high dimensions, and local minima points. This paper reports the use of the SVM regression method to predict changes in the chemical properties of sodic soils un...
متن کاملThe Appraisal use of Gypsum for Reclamation of Solin and Sodice Soils in Southern Khuzestan
Soil correction is one of the ways in agriculture lands development. The sodic ion alongside salin vocalizes the salin-sodic soil and cause divulge in plants growth. So necessary coure of action for the Soil correction by physical and chemical ways such as usage of calsium on the leaching is inevitable. In this study, area soils are digged from deep profiles of 0-20, 20-40, 40-60, 60-80 and 80-...
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...
