Summary: Soil fauna is an important indicator of soil quality. This study aimed to evaluate soil fauna collected using pitfall traps and soil chemical and microbiological properties under different land uses in the Cerrado. The systems evaluated were soybean under 14-year no-till; soybean under 3-year no-till; eucalyptus rows; soybean grown between eucalyptus rows, and native Cerrado. Collected individuals were identified as classes, subclasses, order, or family classes. We evaluated the number of individuals trap-1 day-1, total richness, average richness, Shannon Diversity Index, Pielou Evenness Index, total soil organic carbon (TOC), soil microbial activity, and soil chemical indicators. Data were submitted to one-way ANOVA, and means were compared by the Tukey Test (p<0.05). Principal component analysis and grouping analysis were performed among the groups and number of individuals. We identified 16 groups with a greater occurrence for Collembola, Acari, Formicidae, and Coleoptera. Systems containing threes provided a greater abundance of individuals. The largest populations occurred in the systems with the highest TOC levels. Components of the same silviagricultural system (soybean + eucalyptus) shared the same soil fauna groups, indicating a flow of individuals between these systems. The soybean adoption time under no-till systems does not change the population and diversity of soil fauna groups.
