Sclerolobium paniculatum Vogel (taxi-branco) is a legumenous tree native to the Brazilian Amazon region. It occurs in different types of soil and fix atmospheric nitrogen. The mechanical dormancy of the seeds may be overcome by immersing in boiling water and then removing them from the heat until the water cools to room temperature. The seed germination occurs in approximately 30 days. In greenhouse conditions, taxi-branco does not respond to the application of Ca and S. The critical levels in the soil of these two nutrients were 0.37 meq/100 cm{sup 3} and 5.10 mg/cm{sup 3}, respectively. The silvicultural performance of taxi-branco may be considered satisfactory when compared to other native tree species of the Amazon. In homogeneous plantations, taxi-branco trees produce about eight tons of litter per hectare. Its rapid growth accompanied by a high production of litter and its N fixation qualify this species as potentially suitable for the recuperation of degraded soils by human actions.
