The soil is extremely important for the maintenance of a forest ecosystem, and the agroforestry systems allow considerable improvements in the resource. This study aimed to carry out the physical-chemical characterization of the soil in an agroforestry system and areas of natural regeneration in southeastern Pará. The study area is the Nossa Senhora do Perpétuo Socorro Settlement Project, in the municipality of Nova Ipixuna, Pará, which was divided into an Agroforestry System with five years of implementation and areas of natural regeneration with six and ten years, in which four samples, with three subsamples each, at a depth of 0-20 cm from the soil, to carry out chemical and soil texture analyzes. The data were subjected to the normality test and the principal components, using computer programs. Regarding the normality test, the probability distribution was normal, as for the analysis of variance, the treatments submitted did not show significant difference for all the variables analyzed, and in relation to the multivariate analysis, the formation of groups was not identified. Therefore, there was homogeneity between the physical-chemical characteristics of the agroforestry system and the areas of natural regeneration of six and ten years.
