Representative work: The sandy soil leaks water and fertilizer, and the ecological degradation is serious. The structural characteristics of soft rock and sandy soil are complementary, and the improvement of sandy soil by adding soft rock is of great significance to improve soil fertility, restore biodiversity, and maintain sustainable development of the Mu Us sandy land region. In this study, total organic carbon (TOC), particulate organic carbon (POC), dissolved organic carbon (DOC), easily oxidized organic carbon (ROC), microbial biomass carbon (SMBC), bacterial community structure and crop yield were examined using soft rock:sand volume ratios of 0:1 (CK), 1:5 (C1), 1:2 (C2) and 1:1 (C3). Our results indicat Abstract Desertification is reducing the amount of land available to produce food in semi arid and arid regions worldwide. Management techniques to reduce this problem are needed. This paper investigated if the addition of soft rocks to sandy soils would improve soil resilience and productivity. The model system selected for this study was located in Mu Us, China. Soft rocks are defined as a loose rock layer. Collected soft rock and sand from the same study area were compounded in the volume ratios of 0:1 (CK), 1:5 (C1), 1:2 (C2), and 1:1 (C3). The results revealed that the average content of soil organic carbon (SOC) with increasing soil depth and was 3.11 g kg −1 in the 20 to 30 cm soil de
