Salt-induced land and water degradation in the Aral Sea basin: A challenge to sustainable agriculture in Central Asia
Expansion of irrigated agriculture in the Aral Sea Basin in the second half of the twentieth century led to the conversion of vast tracks of virgin land into productive agricultural systems resulting in significant increases in employment...
Development of Magnesium-Dominant Soils Under Irrigated Agriculture in Southern Kazakhstan
Irrational irrigation practices in the Arys Turkestan Canal command area in the southern part of Kazakhstan have led to the formation of soils with poor physical and chemical properties. To study whether irrigation and leaching practices and/or...
During the past forty years, the Syrian rangelands have been the focal point of government interventions. These had four major components: assertion of state ownership over rangelands, settlement and transformation of herders into farmers...
Yield and water-production functions of two durum wheat cultivars grown under different irrigation and nitrogen regimes
Wheat (TriticumdurumL.) yields inthe semi-aridregions are limitedby inadequatewater supply late in the cropping season. Planning suitable irrigation strategy and nitrogen fertilizationwith the appropriate crop phenology will produce optimumgrain...
Environmental and Economic Benefits of Saline-Sodic Soil Reclamation Using Low-quality Water and Soil Amendments in Conjunction with a Rice–Wheat Cropping System
A combination of appropriate crop rotation(s) and management interventions has the potential to transform saline-sodic soil and water resources from an environmental burden into an economic asset. We carried out 2-year field studies in the Indus...
Optimizing supplemental irrigation: Tradeoffs between profitability and sustainability
Water production functions are used to model yield response to various levels of supplemental irrigation (SI), to assess water productivity coefficients, and to identify optimum irrigation under various input–output price scenarios. The SI...
