Enhancing the productivity of high-magnesium soil and water resources in Central Asia

High-magnesium soils and waters are emerging environmental and agricultural productivity constraints. Excess levels of magnesium (Mg²⁺) in irrigation waters and/or in soils negatively affect soil infiltration rate and hydraulic conductivity and ultimately crop growth and yield. Although the levels of Mg²⁺ in irrigation waters and soils are increasing in several irrigation schemes globally, southern Kazakhstan has become a hotspot of such …
