Abstract

The studied area is located in Porto Trombetas, district of Oriximiná, in the northwest of Pará, state, Brazil and has been subject to bauxite mining. The chemical and biological measurements were made on sites recuperation from 1981 to 1994, and one in Yellow Latosol under secondary forest, taken as reference. The values corresponding to the chemical and biological characteristics were obtained from analyses of the litter layer, light organic matter and soil of the altered and unaltered sites. The data were analyzed using Pearson correlation and Path Analysis. The results given how the chemical an biological composition litter layer and light organic matter were related of the carbon and microbial biomass phosphorus concentration.
