Summary: Population growth and the need for diverse products of origin pressures natural ecosystems, often resulting in imbalances to the natural environment, resulting in fragmentation of remaining vegetation areas. In this sense, the search for sustainable production systems has been increasing considerably in recent years, so that the induction of farming systems that can ally agricultural production to the maintenance of soil quality, ensuring food and soil productivity. Soil cover is of extreme importance for its conservation, since certain crops and soil management can contribute positively even to the maintenance of the edaphic macrofauna, which plays a fundamental role for the establishment of soil quality and its conservation, providing conditions for cultivation. The objective was to evaluate the soil quality under different systems of use through the physical attributes at depths of 0-10 and 10-20 m and diversity of the macrofauna present in the soil and in the vegetation cover, in five areas taken as uses, fragment of Atlantic forest; pasture of Uroclhoa brizantha; Coffee Conilon consorciado with rubber tree; Rubber in monoculture; Conilon coffee grown in monoculture. The work was conducted in a property in the municipality of Jaguaré (ES), using a completely randomized design, with five replications in each area. The physical attributes of the pasture and coffee areas consorted with rubber trees highlight the highest soil density in the two depths studied in the pasture and rubber fields, presenting the highest amount of macro and micropores in the two depths (0-10 and 10-20 cm). For the results of organic carbon and soil nitrogen there was no significant difference between the studied areas. The biological diversity of the macrofauna present in the soil was higher in the coffee growing areas associated with rubber tree, forest / rubber tree and coffee, respectively. The diversity of macrofauna present in the soil cover was higher in the forest area, followed by areas of rubber tree, coffee consorciado with rubber tree and coffee, respectively. The soil cover in the soil was similar for the areas of coffee, forest and coffee consorted with rubber trees, followed by areas of rubber and pasture.
