The forestry of native species in the Amazon still needs studies. This theme, as well as alternative fertilizers and the final disposal of waste, are still little discussed. Therefore, the objective of this work was to analyze the development of the species of Tachigali vulgaris (white tachi) in the Amapá savanna, under mineral and alternative fertilization. Thus, the growth of individuals and the residual effect on soil quality were evaluated, in an experiment with 780 trees, for 8 years after planting. Four randomized blocks were installed, with three treatments (alternative fertilization, mineral and control - without fertilization), in the Embrapa experimental field, municipality of Macapá-AP. The growth in relation to the diameter (DBH) and volume of the white tachi was overwhelming, with a general annual average increase of 2.2 cm in DBH and 1.5 m in volume, however, the height (H) showed growth in 1.6 m due to height being estimated. The seedlings that received alternative fertilization developed better than those with mineral fertilization or without fertilization throughout the evaluated period. Chemical analysis of the land, 5 years after planting and fertilization, showed no significant differences between treatments for soil fertility atributes. This is evidence that the nutrients inserted into the area with fertilization were used to promote greater development of the tachizeiros and that there is no residual effect from them. Furthermore, ICA and IMA showed positive results of 5.2 and 1.5 compared with mineral fertilization and without fertilization. The charcoal mill associated with ash and poultry litter is an alternative fertilization that improves the development of tachi-branco in acidic and low-fertility soils, such as those in the Amapá savannah, and can replace conventional mineral fertilization with advantages.
