ABSTRACT - The Integrated Crop-Livestock-Forestry System (ICLF) emerged as alternative to recover degraded pastures, as well as to improve production systems’ efficiency, in order to make agriculture more sustainable. Research study was implemented in 2018 to assess soil fertility evolution under ICLF system in sandy soil of Bahia State’s Cerrado. Soil fertility assessments were carried out from 2019 to 2022; Cerrado soil was used as basis for initial fertility comparison purposes. Improvement in soil chemical properties was observed after ICLF system implementation in comparison to the Cerrado soil, or to the initial soil condition, since agricultural intensification helped improving nutrient cycling in the system.
