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 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...
متن کاملApplying Biochar and Mineral Amendments to Remediate the Chemical Properties of a Saline-Sodic Soil
The present study was intended to improve the chemical properties of a saline-sodic soil using the individual application of alfalfa residue and two biochars produced from sugarcane bagasse and walnut shell, at the weighting ratio of 5%; their concomitant application with gypsum, aluminum sulfate and the mixture of these two chemical amendments was considered. The experiment was conducted in th...
متن کاملSodic soil reclamation: Modelling and field study
Reclamation of sodic soils has traditionally been undertaken using calculation of gypsum or Ca requirement assuming 100% exchange efficiency and neglect of the contribution of calcium carbonate in the profile. The UNSATCHEM model is reviewed and then evaluated for its ability to predict field reclamation of a sodic saline soil. The 40-ha field site was initially at an electrical conductivity (E...
متن کاملApplication of wastewater with high organic load for saline-sodic soil reclamation focusing on soil purification ability
Fresh water source scarcity in arid and semiarid area is limitation factor for saline-sodic soil reclamation. The reusing of agricultural drainage and industrial wastewater are preferred strategies for combating with this concern. The objective of current study was evaluation in application of industrial sugar manufacture wastewater due to high soluble organic compounds in saline-sodic and sodi...
