California’s Central Valley and surrounding area includes over 18 million acres of grassland, most of which is privately owned and managed for livestock production – creating an excellent carbon sequestration opportunity. Previous studies conducted by WLIC scientists found that a single organic amendment addition to rangeland soils can sequester 55 metric tons of carbon dioxide per acre per year. The Working Lands Innovation Center seeks to expand this line of research by exploring other soil amendments, both alone and in combination, to see if even higher rates of carbon sequestration might be possible.
