“…Covering roughly 40% of the Earth's land surface (Wang & Fang, 2009), grasslands provide an important global ecological service by storing biomass carbon and soil organic carbon (Clark et al, 2020), as well as supporting biodiversity and food security (Hoeffner et al, 2021; Yang et al, 2021). However, changing precipitation and temperature distributions and increasing economic and population pressures have led to forage yield instability and shortages.…”

“…The importance of the global balance between grassland production and its environmental impacts is growing (Cezimbra et al, 2021; Watkinson & Ormerod, 2001). Given the high yield potential of cultivated non‐native grasses, their global production area has increased to meet demand (Foley et al, 2005; Hoeffner et al, 2021; Pellissier et al, 2015; Wang, Dong, et al, 2014; Wang, Vandenbygaart, & Mcconkey, 2014). Endemic to China's pastoral regions, pastureland shortage has led to overgrazing and degradation issues, thereby affecting vegetation, soil physical and chemical characteristics (You et al, 2014), and soil microbiomes (Zhou et al, 2019).…”

Efforts to enhance food, fibre, and forage yields and achieve global food security have included the conversion of natural grasslands to cultivated grasslands. The quantitative effects of a global shift in grassland management on soil properties and microbial communities critical to ecosystem function have remained largely unexplored, particularly on China's Qinghai–Tibetan Plateau. Accordingly, the distinct and contrasting effects of annual Avena grasslands (AAG) versus perennial Elymus nutans Griseb. cultivated grasslands (PEG) on the region's soil properties and microbiome were investigated in an effort to examine their contribution to maintaining soil carbon and nutrients. Across three sites per grassland type, soil moisture content (45.55%), soil organic carbon (48.97 g kg−1), soil total nitrogen (5.13 g kg−1), and soil ammonium nitrogen (298.32 mg kg−1) were 19%–32% greater at PEG sites than AAG sites, whereas soil pH (7.81), soil total phosphorus (0.44 g kg−1), and soil available phosphorus (0.81 mg kg−1) were 2%–31% lower. The AAG and PEG site soils had different bacterial and fungal β‐diversities but similar α‐diversities. The relative combined abundance of Gemmatimonadetes and Chytridiomycota, and that of Rozellomycota individually, were, respectively, higher and lower in AAG versus PEG site soils. This suggests that, on the Qinghai–Tibetan Plateau, contrasting grassland cultivation practices affect soil properties and microbes differently. Given the strong interaction between a soil and its microbiome, changes in a soil's microbial community structure can be expected to substantially alter soil function. This will have important ecological service implications, particularly in terms of carbon storage and water conservation in this ecologically fragile region.

“…Indeed, recent studies showed a stronger beneficial grassland legacy effect on soil structure maintenance and biodiversity conservation. By contrast, water and pathogen regulation and forage production were not affected by the legacy of grassland during the rotation [130,131].…”

The aims of this study were to investigate (i) the influence of aging grassland in the recovery of soil state by the comparison of permanent grassland, two restored grasslands, two temporary grasslands, and a continuous crop in the same pedoclimatic conditions, (ii) the extent and the persistence of the potential changes following a grassland/or cropland phase. We hypothesized that the level of microbial communities and enzyme activities could achieve a profile close to that of permanent grassland after the introduction of grassland for a few years in crop rotations. Soil biophysicochemical properties were studied. Our results indicated that the abundance of microbial communities and enzyme activities were positively correlated to soil C and N contents and negatively correlated to soil pH. The changes in microbial abundance level were strongly linked to the changes in functional level when grasslands are introduced into crop rotations. We also showed that a continuous crop regime had a stronger legacy on the soil biota and functions. By contrast, the legacy of a grassland regime changed quickly when the grassland regime is interrupted by recent culture events. A grassland regime enabled the restoration of functions after more than five cumulative years in the grassland regime.

Grass-based biomass from grasslands can be used as feedstock in green biorefineries (GBs) that produce a range of biobased products. In addition, adjustments made as part of crop rotation to increase areas under temporary grasslands can yield benefits such as carbon sequestration, increased soil productivity, reduced eutrophication and reduced need for pesticides. In this paper, a flexible modeling framework is developed to analyze the deployment options for GBs that use grass-clover to produce protein feed and feedstock for bioenergy. The focus is placed on optimal deployment, considering system configuration and operation, as well as land use changes designed to increase grass-clover cultivation on cropland. A case study involving 17 counties in Sweden showed that the deployment of GB systems could support biomethane and protein feed production corresponding to 5-60 and 13-154%, respectively, of biomethane and soybean feed imports to Sweden in 2020.
