Avaliação do uso de macrófitas aquáticas na recuperação do solo e no desenvolvimento de espécies arbóreas do cerrado em áreas degradadas adjacentes ao reservatório utilizado pela Usina Hdrelétrica Corumbá IV

Abstract

In a small part of the reservoir used by the Usina Hidrelétrica Corumbá IV an experiment was conducted to restore degraded areas using aquatic macrophytes as a nutrient source for reclamation project conducted in the region. This study sought to evaluate the land reclamation and development of the native species planted using the community of microarthropods as an assessment tool. The microarthropods integrate the mesofauna and exert great influence on decomposition processes. Since decomposition is a vital mechanism of soil, the microarthropods themselves are great assessment tools of soil functions. As such, litterbags were used to evaluate their colonization and diversity. The results indicate that when aquatic macrophytes are trasnformed by the composting process they become attractive to the edaphic community as well as in the development of the plants utilized in this study with the exception of Jatobá (Hymenae courbaril).
