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 کاملRedox changes in a small wetland with potential acid sulfate, saline and sodic soils
The study site is a typical, perched wetland in a saline, sulfidic discharge area in the eastern Mt Lofty Ranges near Adelaide, South Australia. The wetland is part of the 10% of strongly waterlogged landscape identified by GIS analysis of a larger 80 km area. Approximately 40% of this area was identified as being poorly drained, but only a small proportion, less than 10%, supports wetland vege...
متن کاملSlight and Moderate Saline and Sodic Soils Characterization in Irrigated Agricultural Land Using Multispectral Remote Sensing
Around the world, especially in semi-arid regions, millions of hectares of irrigated agricultural land are abandoned each year because of the adverse effects of irrigation, mainly secondary salinity and sodicity. Accurate information about the extent, magnitude, and spatial distribution of salinity and sodicity will help create sustainable development of agricultural resources. In Morocco, sout...
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...
