Agroforestry systems have been an alternative of agricultural production that combine food production with the recovery and conservation of the natural resources in the settlement Sepé-Tiarajú, located in the sugarcane region of Ribeirão Preto and first Sustainable Development Project settlement in the State of São Paulo. This study aimed to evaluate the effects of agroforestry systems on soil quality, using 10 qualitative indicators of soil quality, comparing the reports of 10 farmers about the moment when there were no SAFs with the present moment. The results obtained showed that the SAFs contributed to reduce soil compaction, erosion control, increase of humidity retention, soil darkening, increased occurrence of indicator plants of good quality soil, improvement in growth, development, appearance and production of crops, increased occurrence of worms, insects and other organisms in soil and reduction of pest and diseases attacks.
