Summary
The presence or absence of seedlings of Pithecolobium racemosum with the amounts of macro and micronutrients of soils collected in areas with varying degrees of perturbation and at varying distance from the adults are here correlated. For macronutrients, it was found that PO 4 . Ca and Mg have lower concentrations in those areas that have seedlings. With respect to micronutrientes, Mn was lower in areas with seedlings than in areas without seedlings, while the reverse was true for CI. The concentration of AI was quite high in all of the areas studied, and independant of presence or absence of seedlings. It was high when compared with other tropical soils.
