“…For instance, soil bulk density (BD) was found to be lower in grazing exclusion grassland compared to freely grazed grassland due to the elimination of soil trampling by livestock (Gao et al, 2011), as well as the increase of root biomass accumulation (Yuan et al, 2012). The soil particle size distribution revealed that grazing exclusion led to greater silt and clay content, and lower sand content under non-grazed grasslands Mofidi et al, 2013). In addition, grassland with grazing exclusion has higher water-holding capacity, total porosity and infiltration rates; consequently, soil moisture is higher in non-grazed grassland (Yuan et al, 2012;Haynes et al, 2014).…”

“…Some studies have shown grazing exclusion to be associated with several soil physical property variations (Greenwood and McKenzie, 2001;Hoshino et al, 2009;MedinaRoldán et al, 2012;Mofidi et al, 2013). For instance, soil bulk density (BD) was found to be lower in grazing exclusion grassland compared to freely grazed grassland due to the elimination of soil trampling by livestock (Gao et al, 2011), as well as the increase of root biomass accumulation (Yuan et al, 2012).…”

“…In general, soil physical properties improved after grazing exclusion due to natural amelioration of the soil structure. Biological activity due to the growth and decay of plant roots, the activity of soil-dwelling animals, and the wetting-and-drying cycles were the probable mechanisms causing this natural amelioration (Mofidi et al, 2013;.…”

“…Grazing exclusion from the creation of large-scale enclosures has become a common management strategy to prevent grassland degradation and sustain grassland ecosystem function by the restoration of degraded vegetation and improvement of soil quality throughout the world in recent decades (Medina-Roldán et al, 2012;Wu et al, 2010;Mofidi et al, 2013). Previous studies examining the effect of grazing exclusion on grassland have primarily investigated the vegetation productivity, plant species and communities (Gonzales and Clements, 2010;Schultz et al, 2011).…”

Abstract. Since the 1980s, alpine grasslands have been seriously degraded on the Tibetan Plateau. Grazing exclusion by fencing has been widely adopted to restore degraded grasslands. To clarify the effect of grazing exclusion on soil quality, we investigated soil properties and nutrients by comparing free-grazing (FG) and grazing exclusion (GE) grasslands in Tibet. Soil properties -including soil bulk density, pH, particle size distributions, and proportion of aggregatesshowed no significant difference between FG and GE plots.

“…Biomass of perennial grasses, perennial forbs, and annual forbs is greater at exclusion sites than at grazed sites. Meanwhile, the overall grazing exclosure site improves the vegetation composition and soil quality in the Imam Kandi Rangelands (Mofidi et al 2013). However, grazing increases the temperature sensitivity of organic matter decomposition in the soils of temperate grasslands .…”

Understanding the impact of grazing patterns on grassland production is of fundamental importance for grassland conservation and management. The objective of this study is to obtain an understanding of the trade‐offs between aboveground biomass and belowground biomass, which are influenced by environmental factors in free grazing (FG) and grazing exclusion (GE) alpine grasslands on the Tibetan Plateau. We explored the relationships between the trade‐off and environmental factors using correlation analysis, a generalized additive model and a structural equation model, and then found that the key factors that determine trade‐off showed differences in FG and GE grasslands and that the final structural equation modeling result explained that 96% (path coefficient = 0.96) and 65% (path coefficient = 0.65) of the variations in the trade‐off were due to FG or GE classifications, respectively. The results demonstrated that soil organic carbon, soil carbon/soil nitrogen, and soil available nitrogen affect the trade‐off between aboveground and belowground biomass in FG grasslands more obviously than in GE grasslands. However, the effects of growing season temperature on the trade‐off were insignificant, −0.218 and −0.181 in FG and GE grasslands, respectively. FG increased the soil bulk density, which resulted in an alteration in the soil pore size distribution and a greater resistance to root penetration. In addition, FG affected the level of soil nutrition, which will affect the nitrogen mineralization of decomposition and absorption, as well as the root biomass. Consequently, this study can provide guidance to improve the quality of grassland.
