Column leaching experiments on saline soils of different textures in Sistan plain
Salinization is the main characteristic of soils in arid and semi-arid regions which reduce the agricultural potential ofirrigated lands. Therefore, soil reclamation as well as determination of the leaching requirement for salt control is veryimportant for better plant growth. In this study, the effects of leaching on saline soils of Sistan region, southeast of Iranwere examined using unsaturat...
متن کاملInvestigation of Leaching Requirement of Continuous and Alternate Ponding Methods in Saline and Sodic Soils in South of Khouzestan Province
In this study, leaching experiments were carried out by both continuous and alternate ponding methodsin the south of Khouzestan province. In equal applied water leaching, alternate ponding leachingmodel had a better performance than continuous ponding method in desalinization and dealkalization.In term of alternate method,there was not ayn difference between 5 and 8 day periods in one-meterdept...
متن کاملDynamic changes in water and salinity in saline-alkali soils after simulated irrigation and leaching
Soil salinization is a global problem that limits agricultural development and impacts human life. This study aimed to understand the dynamic changes in water and salinity in saline-alkali soil based on an indoor soil column simulation. We studied the changes in the water and salt contents of soils with different degrees of salinization under various irrigation conditions. The results showed th...
متن کاملInvestigation of Leaching Process on Saline and Sodic Soils, and Provide a Suitable Experimental Model for Land Reform in “Southern Khuzestan” Soils
In regions like south of “ khouzestan” that water table are high, under the effect of water rise moving through capillary fringe and its vaporize, the salts move to soil surface and cause salin or salin and sodic soils. Leaching assign as one of those adjustment soils methods. In order to investigate the leaching process and draw the curves of desalinization and dealkalization in region of Dar...
متن کاملThe Effect of Oil Meal as a Micronutrient Fertilizer in Saline and Non-Saline Soils
A significant amount of the oil meal is produced annually in the oil industry. Oil meal addition into the soil can improve the soil organic matter and micronutrients concentration. This study was conducted to investigate the effect of olive, sesame and black cumin meal (0, 2 and 5 g 100g-1 soil) on the soil Cu, Zn and Fe concentration in saline and non-saline soils by a greenhouse experiment. T...
