| Abstract: |
| The objective of this study was to illustrate differences in soil nutrient characteristics under different land uses in north\|eastern Ulanbuh Desert. Soil nutrient characteristics were evaluated under three different types of land uses. The results indicated that the total contents of organic matter, nitrogen, potassium, and phosphorus in soil samples were 8.02±4.35, 0.34±0.14, 0.37±0.09 g·kg-1, and 16.10±2.04 g·kg-1, respectively while the contents of available N, P, and K were 18.48±8.27, 3.76±0.89 mg·kg-1, and 135.04±83.35 mg·kg-1, respectively. The soil pH was 8.8±0.20. Also, it is found that the land use type significantly affected soil organic matter, total P, available N, available P, available K, and pH value but it did not significantly affect the total N and K (P<0.05). The contents of organic matter, total N, total K, total P, available N, available K, available P and pH decreased with increasing soil depth. Based on a comprehensive evaluation of soil fertility, the three plots were ranked from most to least fertile as desert shrub (0.443)＞forest land (0.409)＞farmland (0.312). The desert shrub and forest land were evaluated as medium fertility while the farmland was classified as low in fertility. These results suggested that desert shrub and forest land were more beneficial than farmland for maintaining soil fertility. |
