Deep soil desiccation has become a major obstacle to restoring vegetation in the Loess Plateau region of China. The restoration deep water plays an important role ecosystem health. In present study, we compared effects on moisture variations dry grass cover and clean tillage treatments based in-situ column monitoring for eight years. results showed that layers could temporarily disappear reappear again with rainfall under tillage. However, effectively increased moisture. Grass primarily consumed from shallow layer (0–2 m), total amount during whole growth period was less than annual average index decreased by 24.20 % (2–10 m) recovered 7.5 12.8 after years, recovery 0.66 %. Thus, it would take half year recover stable field capacity 14 years reach capacity. Recovery also depended supply. We found precipitation had obvious lagged effect approximately two supply Our findings contribute understanding how alleviate layer, potentially helpful implications ecological health arid semiarid regions.
