“…siftdesk. org | volume 1: issue 2 larger than 0.25 mm are called macro-aggregates and are very important index to indicate soil structure (Tisdall and Oades 1980).And the content of water-stable macro-aggregates increased with the increased proportions of feldspathic sandstone in the remediated soils (Han et al 2012b), which showed that the remediated soil structure was improved by the increase of the content of feldspathic sandstone added in sand (Han et al 2015). Therefore, the feldspathic sandstone could play a positive role in improving the remediated soil structure.…”

“…For instance, compaction of feldspathic sandstone could be avoided by the dispersion of sand in the remediated soil, creating environment for the plant growth (Han et al 2015). In the presence of sand, capillary porosity and permeability of feldspathic sandstone was enhanced.…”

“…However, sand was uniform or poorly graded and loosely bounded with high permeability but with poor water retention capacity. Desertification generated in sandy land and soil erosion caused by feldspathic sandstone was the reason for severe scarcity of soil and water resources, which caused the farmland reduction accordingly .Considering that the properties of feldspathic sandstone was complementary with that of sand although their properties were obviously different, feldspathic sandstone was used to remediate sandy land to form a remediated soil (Han et al 2015), which could break the hard and compacted structure of feldspathic sandstone, as well as amend loose and porous sand, in order to enhance water productivity and arability of sandy land, contributing to the control of the soil erosion. Furthermore, the strong cementation between remediated soil grains could facilitate to form physical soil crust and to stable sand.…”

“…Furthermore, the strong cementation between remediated soil grains could facilitate to form physical soil crust and to stable sand. In addition, the fair water retention capacity of remediated soil could benefit forming thick frozen soil layer, which played an essential role on the control of wind erosion and the improvement of sand fixation (Han et al 2015).…”

“…For this reason, some literature have been published in recent years studying the methods of remediation of sandy land with feldspathic sandstone (Han et al 2015;Han et al 2012a;Han and Zhang 2014;Wang et al 2014), but their extent has been limited, and specific to an individual study. There is no comprehensive review of this subject as far as we know.…”

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 depth. The highest average content of particulate organic carbon (POC) was observed in the 10-20 cm soil layer (2.72 g kg −1 ). In the 10 to 20 cm soil depth, the polysaccharide content was the highest (125.3 and 119.08 μg g −1 ) in the C1 and C2 treatments. However, in all soil layers the C2 treatment had the highest (0.11 g kg −1 ) content of calcium carbonate. Compared with the CK treatment, the addition of soft rock increased of corn yield, the C2 treatment had the largest increase (65.46%). The corn yield showed a significantly positive correlation with polysaccharides at 10-20 cm. The overall results showed that soft rock o sand ratio of 1:2 could increase the crops yield, which was of great significance to the sustainable development of agriculture in the sand area.

Aeolian sandy soil, common in Mu Us, China has poor structure and water holding capacity. The soft montmorillonite clay stone was used to adjust the structure and characteristics of sand soil. In this study, the soft montmorillonite clay stone was mixed with sand in the volume ratios of 1:1, 1:2, and 1:5. Soil texture, organic matter content (OMC), and effects on crop yield from 2010 to 2018 were determined. When corn (Zea mays L.) was planted, the clay content, fractal dimension (FD), and OMC of the 1:2 compound soil showed a steadily increasing trend with a higher rate than the 1:1 and 1:5 compound soil. When potato (Solanum tuberosum L.) was planted, the increasing rates of the FD and OMC were largest in the 1:5 compound soil. Potato planting increased the FD of the soil particles by 15.3%, and the OMC was 13.76 times higher than it was prior to planting. Corn and potato crops had the largest sustainable yield index (SYI) and average yield, and the smallest coefficient of variation (CV) in the 1:2 and 1:5 compound soils, respectively. This indicated that 1:2 and 1:5 compound soils allowed for the highest yield stability and sustainability. The 1:2 and 1:5 compound soils were suitable for corn and potato growth, and the compound soil properties exhibited a sustainable and stable development trend. Therefore, this indicates that 1:2-1:5 compound ratios can be used as the optimum sand clay ratios for improving the characteristics of aeolian sandy soil using soft rock.
