 The Status and Evaluation of Main Soil Nutrients in Xilin Gol GrasslandJiguang Shi Asian Agricultural Research, 2014, vol. 06, issue 03, 5 Abstract: To reveal the soil nutrient contents of Xilin Gol Prairie, practical data on the main soil nutrient contents from 2006 to 2011 were statistically analyzed and integrated evaluation of soil nutrients was finished on principal component theory. The result showed that the soil nutrients of Xilin Gol Grassland were mainly organic matter, the content of total N, total P and total K were 22.444 g/kg, 1.047 g/kg, 0.371 g/kg and 23 g/kg respectively, and the degree of variation of each other was moderate except total K’s little variability. The contents of soil nutrients were in the moderate level, in which contents of organic matter and total N were in the moderate level (Level 3), content of total P was low level (Level 5), and the content of was much high level (Level 2). The regional integrated evaluation showing that the soil nutrients of Xilinhot was the highest level and Erenhot was the lowest level; the meadow steppe was the highest following by the typical grassland and the grassland as desertification was the lowest, provided a theoretical basis for promoting the restoration of farmland to forest and pasture and the development of animal husbandry and improving the grassland productivity and reasonable utilization of grassland resources.
