Deposition and nutritional quality of the litter of pure stands of Eucalyptus camaldulensis and Acacia mangium
The aim of this study was to evaluate the contribution of pure stands of Eucalyptus camaldulensis and Acacia mangium for litter deposition and nutrient return in a pit of clay extraction in northern Rio de Janeiro (RJ). We conducted a randomized block design experiment with two treatments and three...
