Paper: “Impacts of Organic Matter Amendments on Carbon and Nitrogen Dynamics in Grassland Soils,” Soil Biology & Biochemistry 68 (2014): 52e61

Research Team: Rebecca Ryals, Michael Kaiser, Margaret S. Torn, Asmeret Asefaw Berhe, and Whendee L. Silver, (Department of Environmental Science, Policy, and Management, University of California at Berkeley, and  School of Natural Sciences, University of California at Merced and  Lawrence Berkeley National Laboratory, Earth Sciences Division,  Berkeley, )

Findings: This paper showed that compost applications led to an increase in bulk soil C stocks and that an increase in the free light and occluded light C fractions was seen over three years. It is important to note that compost was hand-sorted from soils prior to analysis so the increase in soil C represents mostly new plant derived carbon in the system.

Research Team: Marcia S. DeLonge, Justine J. Owen and Whendee L. Silver (Ecosystem Science Division, Department of Environment Science, Policy, and Management, University of California at Berkeley)

Findings: Management practices that conserve and enhance C storage in rangeland soils and vegetation can help mitigate climate change while enhancing sustainability under future climate scenarios.
