Abstract
Collembola is considered one of the most representativ groups of edaphic fauna. Its representatives have a wide distribution in the most varied types of soil and exert a significant influence on the microbial ecology of the soil, nutrient cycling and soil fertility. The study sought to analyze the chemical characteristics of the soil with the taxonomic richness and abundance of the Collembola fauna in the phytophysiognomies of primary forest, oil palm plantation and agroforestry system, in the municipality of Santa Barbara, Pará. Four field trips were carried out, with an area of 50x25 m being determined, with 12 sampling points, where pitfall traps were installed, which totaled 144 samples. The samples were preserved in 70% alcohol, and the springtails were quantified and identified at the family level. For the chemical characterization of the soil, a total of 108 samples were obtained with laboratory determination for each phytophysiognomy of pH, Al, Ca, Mg, K, P, N, Corg, Fe, Cu, Zn, Mn, CTC, SB, Cmicrob., Hmicrob., and moisture. This indicates that the colembofauna is strongly influenced by the chemical attributes of the soil and by the different phytophysiognomies.
