SUMMARY:

Due to its economic potential and its silvicultural characteristics, the Brazil nut (Bertholletia excelsa) has been one of the main native forest species indicated for the recovery of degraded areas in the Amazon. In the actions developed in Carajás, the mining company carries out a program for the recovery of degraded pasture areas with the use of this species as a form of environmental compensation for the impacts caused by its activities. Previous experiments in the region suggest that competition for light between grass and other herbs with Brazil nut seedlings is probably an important ecological bottleneck for successful plantations of this tree species. The present work aims to test the use of alternative silvicultural techniques to combat the competition of seedlings of Bertholletia excelsa with grass and other invasive herbs in areas of degraded pastures, through the use of palm leaf bioblankets, synthetic geotextile blankets and manual mowing. . These three treatments will be compared with each other and with the control, as well as with the conventional treatment used by the company until now, based on the use of hydrogel in the pit, periodic chemical fertilization and herbicide application. Thus, alternative techniques applicable on a large scale are sought to implement Brazil nut groves in areas of degraded pastures, which minimize the use of chemical inputs and maintenance activities.
