Spatial distribution and simulation of soil moisture and salinity under mulched drip irrigation combined with tillage in an arid saline irrigation district, northwest China

Hetao Irrigation District, a large irrigation district in arid area, northwest China, is suffering from the decreasing water supply and increasing soil salinization. Mulched drip irrigation is widely used for agricultural production in arid area, and tillage management affects soil environment variously. This study aimed to explore combined effects of tillage and mulching modes on soil water and salt transfer under drip irrigation. The...
