Agroforestry systems (SAF maintain intermediate levels of biodiversity between natural forests and agricultural systems. Using soil quality indices, it has been shown that SAFs can reduce soil degradation over a long period of time. This research was conducted to evaluate the effect of four SAF on the quality of a soil degraded by overgrazing. SAFs A, B, and C were three years old and had centrocema cover (Centrosema macrocarpum), SAF D was four years old and had no cover, and the control was a degraded pasture. Sampling was done during the dry season. The experimental design used was complete randomized blocks with three repetitions, two sampling sites and two depths. Soil quality indicators evaluated were: fungi, bacteria and actinobacteria population, mycorrhizal infection percentage, mycorrhizal spore count, basal respiration rate, microbial biomass carbon, bulk density, gravimetric moisture content and oxidizable organic matter and extractable phosphorus (Olsen) contents. The Weighted Soil Quality Index (ICSw) was higher for SAF than for degraded pasture, thus demonstrating that SAFs favored the recovery of soil quality. The indicators most influenced by the SAF were microbiological: HMA spores, mycorrhizal infection, population of bacteria, actinobacteria and fungi, and microbial biomass.
