Applying 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 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 کاملImproving Soil Physical Indicators by Soil Amendment to a Saline-Sodic Soil
The application of organic amendments can be an appropriate solution to reclaim and improve physical propertiesof saline-sodic soils. In this research, an experiment was performed under greenhouse conditions to study the effect ofamendments to the physical properties of loamy saline-sodic soil. The five treatments were control (withoutamendment), municipal solid waste compost (MC), vermicompost...
متن کاملExamination of different leaching methods of solublesalts from saline and sodic soil profiles
Increasing of population in the world caused overusing natural resources and land destruction. Salinization and sodification are two effects of land destruction. Leaching of soil soluble salts is the most appropriate method to emend and reclaim saline and sodic soils. In this study, Examination of different leaching methods of saline from sodic soils has been evaluated in Veis Area in Khoozesta...
