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...

Soil salinization and sodification are common processes that particularly characterize drylands. These can be attributed either to natural conditions or anthropogenic activities. While causes include factors such as climate, lithology, topography, pedology, human mostly related agricultural land-use, specifically, irrigated agriculture. The objective of this study was thoroughly review topic, w...

In the conditions of grey soils in south Kazakhstan, soil is degraded due to irrational use irrigated land and non-compliance with agro-reclamation works its order, as well excessive irrigation medium-saline soil, it negatively affects crop yields. addition, on soils, winter plowing carried out only a shallow depth 30-32 cm. Mainly timely intensive treatment, preferable, since degree bulk mass ...

Saline-sodic soils are susceptible to wind and water erosion when the dispersive effect of sodium overcomes inter-particle bonds. Rheological parameters viscoelasticity can help quantify attractive forces account for salinity in these soils. The main objective present study was investigate behavior saline-sodic Sirjan playa south-central Iran. Three representative pedons were excavated describe...
