Edaphic invertebrates in different coffee management systems in Zona da Mata of Minas Gerais

Abstract

The edaphic faunal contributes to the decomposition of organic matter and soil structure, so their identification and quantification are essential to understand the biological interactions of the soil/plant. The edaphicfaunal communities clearly reflect differences in vegetation and management practices. This research aimed to evaluate the abundance and fairness of the macro and mesofaunal of the soil against the typeof agricultural management in coffee growing areas in three types of management: conventional system, CONV, agroecology,AGRO, agroforestry, SAF, and forest, MATA, next to each management system, valued at two times of collection. Forthe evaluation of macro and mesofaunal hypogeum edaphic, were collected all the litter on the soil surface and soil blocks from 20 x 20 x 10 cm. Soil and litter were placed in Berlese funnels for seven days, and pitfalls traps installed in the field for 72 hours. The variables were the abundance, richness, diversity and soil animal functional groups. The collection periods influenced the abundance of wildlife richness and diversity of groups. The groups collected edaphicfaunal are present in all management systems with coffee, except for the group Opiliones. Traps pitfalls wealth was greater than that of soil and leaf litter. The groups were Formicidae and microphagous dominant in agroecossitems evaluated in both samplings.
