Abstract: A comparative study was made on the soil fertility in Moyu County of Xinjiang under effects of four sand control engineering measures. Differences were observed in the soil pH and nutrient contents under different sand control engineering measures. The soil pH value followed the order of natural sparse vegetation fencing area > grass grid and artificial forest > artificial forest > area collocated with multi-plants, and was significantly higher under natural sparse vegetation fencing area (P<0.05). The soil nutrient contents were affected by the duration of plant establishment. In the artificial forest having been established for three years, the contents of soil organic matter, total nitrogen, available nitrogen, total phosphorus, available phosphorus, and available potassium were higher than those in the newly established (half year) grass grid and artificial forest area. In the area collocated with multi-plants, the contents of soil organic matter, total nitrogen, available nitrogen, total phosphorus, and total potassium were higher, but the soil available phosphorus and potassium contents were relatively lower than those in other test engineering areas. Therefore, P and K fertilizers should be applied in the area collocated with multi-plants.
