To analyze how the soft rock influence the moisture storage capacity of sandy soil, experimental plots with different ratios of soft rock and sandy soil were set in Mu Us sand land, with spring maize planted one season per year, and the soil moisture of the depth 0-120 cm was frequently monitored during 2013-2015. The results showed that moderate soft rock could improve the moisture storage capacity of sandy soil from 100 mm in 2013 to over 200 mm in 2015, promote the soil moisture to none deficiency state, strengthen the moisture storage capacity of soil, which was beneficial for the crop growth. Moisture storage capacity of soil layer below 40 cm was promoted most obviously, and the layers of 0-40 cm and 80-120 cm turned into more stable layers for moisture storage, which was helpful for the crops. Between the soft rock and sandy soil with ratio 1:1 to 1:5, with the addition of soft rock, the moisture storage capacity of the soil was enhanced, but not significant.
