Effects of Fencing on Vegetation and Soil Nutrients of the Temperate Steppe Grasslands in Inner Mongolia

Grazing exclusion has been widely implemented in degraded grassland. However, the changes of plant communities and soil nutrients response to fencing are still controversial. Thus, effects free grazing, 17 36 years on biomass litter biomass, carbon (C), nitrogen (N) phosphorus (P) concentrations stocks plant, were investigated temperate steppe grasslands northern China. The results indicated that increased aboveground live biomass. In addition, C, N P soil. Although root its nutrient also significantly by fencing, they decreased with extending from years. Moreover, there no significant differences between fencing. Litter positively correlated stocks. Our demonstrated is an effective way restore vegetation Inner Mongolia, but a longer duration further positive production accumulation.
