<br/><br/> <br/><br/>ABSTRACT<br/><br/>The objective of this study was to evaluate the occurrence of the soil macrofauna in coffee<br/>production systems, as well as their relationship with edaphic properties. Therefore, two coffee<br/>production systems were selected: coffee plantations at full-sun with conventional management<br/>(Intensive) and shaded coffee plantations with organic management (Traditional). In each crop<br/>system, three soil samples were collected randomly, in the form of blocks (25 × 25 cm), to a soil<br/>depth of 10 cm. In total, 17,109 individuals were recorded in this study being the Oligochaeta<br/>group the most representative, regardless of the coffee production system. The average density of<br/>soil macrofauna was higher in traditional coffee plantations (p < 0.05) due to the higher density<br/>of Oligochaeta, Diplopoda and Blattodea. The traditional coffee plantations provided a better<br/>soil chemical fertility reflected in the principal component analysis. Furthermore, these chemical<br/>attributes probably could affect the occurrence of the soil macrofauna groups.<br/><br/>Keywords: co-inertia analysis, organic management, shade trees, edaphic fauna.
