RESUMO:

In an area under the influence of bauxite mining in the mine of the company Mineração Paragominas SA of the Hydro group in the Miltônia Plateau 3. Samples were collected from 5 recovery areas and a forest area that served as soil reference in its state natural, to study them as to their morphological, chemical and physico-hydraulic characteristic, with the objective of studying the soils constructed after bauxite mining in order to characterize the evolution and recovery of the soils under different recovery methods and different ages in order to know the proper conditions for the establishment of planted or regenerated vegetation. In soils constructed part of the morphological characteristics related to color and structure is inherited from the original soil, however it is common structural changes related to compaction. No major evolution of the pedogenetic processes was observed and the formation of a new structure was observed only in the superficial layer in the older areas. Among the five systems studied in different years, the natural Regeneration system with 7 years showed a greater potential for recovery of the physical attributes of the soil of areas degraded by bauxite, presenting improvements in these attributes mainly in the superficial layer. The RN7 system obtained the best responses of the soil attributes, which were the stability of aggregates in water, infiltration of water in the soil, organic carbon, availability of nutrients in surface and sub-surface, if approaching more of the reference area, native forest
