ABSTRACT

In areas where soil surface horizons were removed, the main edaphic problems are reduced amounts of organic matter and nutrients. Revegetation, especially with native species, has been indicated to recover these areas. Under this perspective, the present research has been developed to evaluate the contribution of organic and agro-industrial residues, as conditioners of soil fertility and their effects on initial growth of 'Jatobá-do-cerrado' seedlings. The treatments consisted of 4 agro-industrial residue doses (0, 15, 30 and 45 Mg ha^-1) and 4 organic residue doses (0, 8, 16 and 32 Mg ha^-1), with 16 treatments and 10 replicates. After 8 months of development, the soil was evaluated for phosphorus, organic matter, hydrogen potential, potassium, calcium, magnesium, potential acidity, aluminum and sum of bases, and plants were evaluated for leaf chlorophyll, height, collar diameter, fresh and dry matter of shoots and roots, and root length. The addition of residues to the degraded soil increased the fertility by raising calcium and magnesium levels. Agro-industrial residues contributed to increasing height, shoot dry matter and chlorophyll of H. stigonocarpa, while organic residues improved shoot fresh matter and chlorophyll.
