Efficiency of sulfur application with different sizes and rates in reclamation of a saline-sodic soil in laboratory columns

Stability 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...

Application 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...

Reclamation of a salin-sodic soil in kuzestan iran

the role of application of dynamic assessment approach in improvement of iranian efl writing performance at different language proficiency levels

the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...

Sodic 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...

Examination 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...
