This study evaluates the cause of salinization in an irrigation scheme 100 ha supplied from a reservoir. The is located Gumselasa catchment (28 km2), Tigray region, northern Ethiopia. underlain by limestone–shale–marl intercalations with dolerite intrusion and some recent sediments. Water balance computation, hydrochemical analyses water quality methods were used this investigation. Surface wat...

Soil salinization is increasing steadily in many parts of the world and causes major problems for plant productivity. Under these stress conditions, root-associated beneficial bacteria can help improve plant growth and nutrition. In this study, salt-tolerant bacteria from the rhizosphere of Uzbek wheat with potentially beneficial traits were isolated and characterized. Eight strains which initi...

Salinity in agricultural land is a major problem worldwide, placing a severe constraint on crop growth and productivity in many regions, and increased salinization of arable land is expected to have devastating global effects. Though plants vary in their sensitivity to salt stress, high salinity causes water deficit and ion toxicity in many plant species. Considerable efforts have therefore bee...

The article dwells upon the study of current physico-chemical status alluvial dark-humus soils floodplain hayfields Volga-Akhtuba and Volga delta. Alluvial are formed in special semiaquatic conditions; they result soil-forming processes. Considered to be dynamic both natural anthropogenic conditions. They have subordinate remain barriers accumulators various chemical elements while performing a...
