Plant-soil interactions in grasslands of the Mongolian Plateau under global change.

Increased atmospheric N deposition and altered precipitation regimes are two important global-change factors influencing grassland communities by changing soil nutrient availability and acquisition by plants. These findings highlight that mowing cannot mitigate the negative effects of N enrichment on soil MBC, and that soil, plant and microbial properties play important roles in the response of soil MBC to mowing in N-enriched soil. Liu et al. ([22]) reported that water supply significantly affected plant C:N and N:P ratios, and these effects differed among plant species of Inner Mongolian grasslands. Given the importance of plant-soil interactions in grassland ecosystems, it is necessary to evaluate the roles of plant-soil interactions in response of grasslands in MP to global change and human activities.
