Compost amendments to grasslands have been proposed as a strategy to mitigate climate change through carbon (C) sequestration, yet little research exists exploring the net mitigation potential or the long-term impacts of this strategy. We used field data and the DAYCENT biogeochemical model to investigate the climate change mitigation potential of compost amendments to grasslands in California, USA. The model was used to test ecosystem C and greenhouse gas responses to a range of compost… 


Land management offers significant potential to both help lower greenhouse gas emissions and reduce atmospheric carbon dioxide. The goals of this research were to determine the shortand long-term

Long‐term impacts of manure amendments on carbon and greenhouse gas dynamics of rangelands

Manure applications increased NPP and soil C storage, but plant community changes and GHG emissions decreased, and eventually eliminated, the net climate benefit of this practice.

Compost amendment to enhance carbon sequestration in rangelands

Rangelands contain 20% of global soil carbon (C). Past management of rangelands has resulted in significant losses of soil C, threatening the long-term productivity and sustainability of these

Organic amendment additions to rangelands: A meta‐analysis of multiple ecosystem outcomes

A global meta‐analysis of 92 studies in which organic amendments had been added to arid, semiarid, or Mediterranean rangelands found that organic amendments, on average, provide some environmental benefits, as well as some environmental harms.

Carbon Footprint of Mediterranean Pasture-Based Native Beef: Effects of Agronomic Practices and Pasture Management under Different Climate Change Scenarios

The results showed that the current beef carbon footprint could be significantly reduced by switching to reduced tillage systems, and conservation tillage practices were shown to be effective in mitigating greenhouse gas emissions.

Near-term potential of organic waste management infrastructure for soil carbon sequestration in rangelands

Contemporary food and agricultural systems degrade soils, pollute natural resources, and contribute to greenhouse gas emissions. The waste output from these systems, however, can be repurposed as an

Managing cropland and rangeland for climate mitigation: an expert elicitation on soil carbon in California

Understanding the magnitude of and uncertainty around soil carbon flux (SCF) is important in light of California’s efforts to increase SCF (from the atmosphere to soils) for climate change

The role of soil carbon in natural climate solutions

Mitigating climate change requires clean energy and the removal of atmospheric carbon. Building soil carbon is an appealing way to increase carbon sinks and reduce emissions owing to the associated

The potential of agricultural land management to contribute to lower global surface temperatures

It is shown that sequestration of 0.68 Pg C year−1 for 85 years could lower global temperature by 0.1°C in 2100 when combined with a low emission trajectory [Representative Concentration Pathway (RCP) 2.6].

It is concluded that a single application of composted organic matter can significantly increase grassland C storage, and that effects of a one application are likely to carry over in time.

Nitrogen pools and fluxes in grassland soils sequestering carbon

Carbon sequestration in agricultural, forest, and grassland soils has been promoted as a means by which substantial amounts of CO2 may be removed from the atmosphere, but few studies have evaluated

Long-term effect of a single application of organic refuse on carbon sequestration and soil physical properties.

Evaluated long-term effects of a single addition of organic refuse to the degraded soils to increase the potential for C sequestration was effective and higher saturated hydraulic conductivity, aggregate stability, and available water content values and lower bulk density values were measured in the restored plots.

Carbon cycling and sequestration opportunities in temperate grasslands

Abstract. Temperate grasslands account for c. 20% of the land area in Europe. Carbon accumulation in grassland ecosystems occurs mostly below ground and changes in soil organic carbon stocks may


Grasslands are heavily relied upon for food and forage production. A key component for sustaining production in grassland ecosystems is the maintenance of soil organic matter (SOM), which can be


ABSTRACT: Management of rangelands can aid in the mitigation of rising atmospheric carbon dioxide concentrations via carbon storage in biomass and soil organic matter, a process termed carbon
