FORAGES AND PASTURES SYMPOSIUM: Improving soil health and productivity on grasslands using managed grazing of livestock.
Beyond grazing, managed grasslands provide ecological services that may offer economic incentives for multifunctional use. Increasing biodiversity of plant communities may maximize net primary production by optimizing utilization of available light, water, and nutrient resources; enhance production stability in response to climatic stress; reduce invasion of exotic species; increase soil OM; re...
متن کاملManaged livestock grazing is compatible with the maintenance of plant diversity in semidesert grasslands.
Even when no baseline data are available, the impacts of 150 years of livestock grazing on natural grasslands can be assessed using a combined approach of grazing manipulation and regional-scale assessment of the flora. Here, we demonstrate the efficacy of this method across 18 sites in the semidesert Mitchell grasslands of northeastern Australia. Fifteen-year-old exclosures (ungrazed and macro...
متن کاملO'connor: Nitrogen Balances in Grasslands Nitrogen Balances in Natural Grasslands and Extensively-managed Grassland Systems
An approach is outlined for synthesising current understanding of nitrogen dynamics in natural grasslands and extensively managed grassland systems. The increasing complexity of models is illustrated from recent literature, first conceptualising and eventually process-simulating the dynamics of nitrogen, especially in the soil sub-systems of grasslands. Some comparisons are made between New Zea...
متن کاملHeterogeneous microcommunities and ecosystem multifunctionality in seminatural grasslands under three management modes
Increasing attention has been paid to the relationship between biodiversity and ecosystem functioning (BEF) because of the rapid increase in species loss. However, over the past 20 years, most BEF studies only focused on the effect of species diversity on one or a few ecosystem functions, and only a few studies focused on ecosystem multifunctionality (i.e., the simultaneous provision of several...
متن کاملManaged grasslands: A greenhouse gas sink or source?
[1] We describe a unique, one year investigation of CO2 and N2O fluxes over a fertilized grassland in Ireland using two eddy covariance systems. As the global warming potential (GWP) of N2O is 296 (100 year time horizon), relatively small N2O emissions have a potentially large impact on overall radiative forcing. Therefore nitrogen fertilizer application practices may possibly turn a site with ...
