Central Asian farmers use the Soviet era-developed method of irrigation which divides the irrigated areas in Hydro Module Zones (HMZ). Each HMZ has a set of crop-specific recommendations for irrigation based on a) soil characteristics (thickness of soil layers, soil texture) and b) depth of groundwater table. These recommendations have not been revised against changes in cultivars and fluctuations in groundwater table during past decades.
