Abstract	The aim of this study was to evaluate the production and accumulation of litter, nutrient content, structural components (cellulose and lignin) and secondary metabolites (polyphenols), in two leguminous trees plantations; Acacia auriculiformis and Mimosa caesalpiniifolia with a potential for recovery of degraded pastures. This study was conducted in Conceição de Macabu, RJ, in a Red Yellow Latosol. Litter was quantified for one year and its attributes determined in the three forest systems. Acacia auriculiformis presented the highest total biomass (10.59 Mg ha-1) and leaf (5.8 Mg ha-1) in accumulated litter, and the highest amounts of C, N and Ca in the leaf. The sequence of nutrient stocks in litter was the same for all components and forest covers: C > N > Ca > Mg > K > P. Mimosa caesalpiniifolia showed the highest litter turnover rates (k = 0.79) and the lowest mean residence time of nutrients for all nutrients, polyphenols, lignin and cellulose. Acacia auriculiformis had the highest variability for all nutrients in the litter, while Mimosa caesalpiniifolia had higher total biomass production (5.35 Mg ha-1 yr-1). The three systems presented high nutrient use efficiency for P. The attributes of the litter revealed differentiated capabilities of the leguminous and secondary forest to recycle nutrients, and the leguminous trees are a good alternative for restoring degraded pastures by improving the soil fertility level through nutrient cycling via litter fall.
