Soil Organic Carbon is Increased in Mixed-Species Plantations of Eucalyptus and Nitrogen-Fixing Acacia
Soil organic carbon (soil C) sequestration in forests is often higher under nitrogen (N2)-fixing than under non-N2-fixing tree species. Here, we examined whether soil C could be increased using mixed-species plantations compared to monocultures, which are less productive aboveground than mixtures. In addition, we compared soil C sequestration under N2-fixing trees with non-N2-fixing trees that received N fertilizer. Monocultures of Eucalyptus globulus (E) and the N2-fixing Acacia mearnsii (A)...[Show more]
