Summary: The soil fertility evolution was monitored in a Red Latosol, very clayey texture, under intensive management in a crop-livestock integration system, conducted for 15 years. The indicators of soil productivity potential and ?bioavailability? of macro and micronutrients were monitored in different glebes, cultivated with grain crops, forage, and pasture, in rotation, succession and intercropping systems. In general, it was possible to maintain satisfactory conditions of chemical soil fertility over time, especially considering that it is a realistic management/production scheme, analogous to a small rural property. Nevertheless, there were possibilities for improvements in nutritional monitoring and management of correction and fertilization of the glebes. The results of the soil fertility indicators reveal some interesting results that serve as a basis for decision making in this area and, mainly, in future works to be developed with intensive production systems. The first aspect is related to the planning for carrying out soil sampling, considering the need to obtain more consistent and standardized results. Another aspect refers to establishing fertilization programs using the concept of fertilization of production systems according to the requirements of the crops and export of nutrients, taking into account the purpose of exploration, whether for the production of grains, silage, or forage
