Conversion Factors to Estimate Soil Salinity Based on Electrical Conductivity for Soils in Khorezm Region, Uzbekistan
This paper compares different procedures for soil salinity analyses to determine
electrical conductivity: saturated paste extract (ECe), xed soil:water
ratio extracts EC1:1 and EC1:5, and soil solution paste prepared with ...
Environmental factors of spatial distribution of soil salinity on flat irrigated terrain
Inefficient irrigation and the excessive use ofwater on agricultural land in the Aral Sea Basin over several decades
have led to saline soils. The main objective of this paper is to identify the environmental predictors ...
Soils and Soil Ecology in Khorezm
The current status of the agricultural soils in Khorezm is closely linked to their development influenced by past river flows and more recent human-managed irrigation and drainage practices. The initial relief of the ...
Managing Soil Salinity in the Lower Reaches of the Amudarya Delta: How to Break the Vicious Circle
This case study focuses on the vicious circle of soil
salinization: agriculture’s consumption of large
amounts of water contributes to shallow groundwater,
leading to recurring soil salinity, which in
turn demands more ...
Geostatistical monitoring of soil salinity in Uzbekistan by repeated EMI surveys
Soil salinization in the lower reaches of Amudarya is a constant threat. High seepage losses in irrigation water delivery
network and deteriorated drainage network result in rising groundwater tables. The shallowgroundwater
table ...
Табиатни муҳофаза қилиш устидан давлат бошқаруви (Study Program for the course in “State management in nature protection”)
Жаҳон тараққиётининг ҳозирги босқичида экология билан боғлиқ масалалар, табиат экотизими емирилишининг кенгайиб бориши, биологик хилма-хилликнинг қисқариши, табиий муҳит глобал ўзгаришининг таҳдиди, саноат объектларидаги ...
Conservation agriculture in Central Asia—What do we know and where do we go from here?
Rainfed and irrigated agricultural systems have supported livelihoods in the five Central Asian countries
(CAC) for millennia, but concerns for sustainability and efficient use of land and water resources are longstanding.
During ...
Comparison and sensitivity of measurement techniques for spatial distribution of soil salinity
In Khorezm, a district of Uzbekistan situated in the Aral Sea Basin, soil
salinization is an important driver of soil degradation in irrigated agriculture. The main
objective of this study was to identify techniques that ...
The assessment of spatial distribution of soil salinity risk using neural network
Soil salinity in the Aral Sea Basin is one
of the major limiting factors of sustainable crop
production. Leaching of the salts before planting
season is usually a prerequisite for crop establishment
and predetermined water ...
