AbstractThe water consumption by agriculture accounts for most part of water resources in the continents. Specially, in the arid and semi-arid areas of the world, it accounts, for example, for more than 80% of the total water consumption in the northwestern China. And most part of water for agriculture is originated from rainfall. Zeolite, which is distinguished by the properties of high cation exchange capacity (CEC), free structural water storage and surface adsorption, was applied in the present study in the fine-grained calcareous loess soil to enhance rainfall infiltration and soil water retention. The results show that soil treated with zeolite, compared with the normal soil, could increase infiltration by 7%-30% on gentle slope land and more than 50% on steep slope land, respectively. In addition, the treated soil could increase soil moisture by 0.4%-1.8% in the extreme drought condition, and 5%-15% in general situation. Consequently, it can reduce overland flow (surface runoff) and protect soil from erosion. And furthermore, can regulate water supply for crops in severe drought conditions. Thus, zeolite has special properties that can be potentially applied to water efficient use for dryland farming. But some technological aspects need scientific investigation and experiment before it puts into broad implementation.
