Special Issue Information

Dear Colleagues,

Grassland ecosystems provide important ecological services and functions such as forage production for animal husbandry, biodiversity conservation, soil and water conservation, carbon storage, water resource regulation, etc. Recent decades, however, have seen rapid climatic warming and changes in precipitation regimes worldwide—e.g., an increase or decrease in precipitation and an increase in annual mean air temperature. Even minor disturbances to grassland habitats may substantially alter above-ground community and below-ground soil processes, and function changes of grassland ecosystems. Hence, above- and below-ground responses of grassland ecosystems to climatic changes and human disturbances have recently drawn significant interest and become a global concern.

The subject of this research topic is to explore the above-ground community and below-ground soil processes, function changes, and driven mechanisms of grassland ecosystems (natural grassland and artificial grassland) responding to direct changing climate or indirect microclimate change caused by disturbances (e.g., dynamics of temperature and precipitation, extreme weather events, grazing disturbance, ecological restoration or protection projects).

We invite papers from researchers to share new ideas, techniques, and findings about this subject from field control test experiments, temporal and spatial-scale studies, or remote sensing studies. These studies will provide insight into the effects of the direct changing climate or the indirect microclimate changing on the above-ground community and below-ground soil processes, and function changes of grassland ecosystems. This is key to predicting future successions of grassland ecosystems under the ongoing global climate and microclimate changes. These studies will influence the future development of adaptive management practices for grassland ecosystems under the ongoing climate change.

We invite papers from researchers to share findings from the spatial–temporal response of natural grassland and artificial grassland under the changing environment based on orientation observations, control experiment research, and spatial analysis research.

The production and forage quality of semi-natural hay meadows of Arrenatheretalia in the southern central Pyrenees were studied according to the time of mowing within the vegetative cycle, to determine its optimum moment. The results show important variations according to the meadows and the year. Higher productions (56% in kg DM ha−1, 42% in UFL ha−1) and lower qualities (−12% in CP, −11% in UFL kg DM−1, −7% in PDI and −17% in RFV) were obtained in the year in which temperatures and rainfalls were the highest. It is concluded that the timing (advance or delay) concerning the maximum value of production and the quality (two years) do not have a direct relationship with the variations of accumulated rainfalls and the growing degree days. The decreases in production (18% in kg DM ha−1 and 25% in UFL ha−1 until 24 June) and quality (26% in CP, 16% in UFL kg DM−1, 13% in PDI and 20% in RFV until 24 June) were also quantified from their maximum values within the traditional mowing period. The optimal time for mowing is between 20 May and 20 June, depending on the annual weather and the meadow characteristics. Full article

Soil-dissolved organic matter (DOM) drives the carbon (C) and nitrogen (N) cycles in agroecosystems. Despite many studies on DOM dynamics, hardly any attention has been directed toward DOM quality, particularly DOM composition. The aim of this study was to elucidate how C and N management practices alter soil water-extractable organic matter (WEOM) in a loess soil agroecosystem. Field experiments were conducted with a winter wheat monoculture. Three N fertilization rates (0, 120, and 240 kg ha−1 year−1) were applied for 17 years (2002–2019), combined with five C practices (zero, low, and high rates of sheep manure or wheat straw) for three years (2016–2019). The results reveal that soil organic carbon (SOC) and water-extractable organic carbon (WEOC) concentrations in the topsoil (0–20 cm) were increased by organic amendments considerably but were not affected by N fertilization. The fluorescence excitation–emission matrix spectra (EEM) of WEOM were resolved to two humic-like components (C1 and C2) and two soluble microbial byproduct-like components (C3 and C4). The proportions of C1 and C2 were increased, while the proportion of C3 was decreased by both C and N management practices. In conclusion, organic amendments increased both WEOM quality and its proportion of humic-like components, whereas N fertilization increased the proportion of humic-like components without variations of WEOM quality in the topsoil of loess soil.
