SUMMARY:

Since the period of post-indigenous colonization, after the discovery of gold in Minas Gerais, in the dairy micro-watershed of Ribeirão das Furnas, in the municipality of Aiuruoca, southern Minas Gerais, natural pastures and later pastures formed with exotic species have been the main source of food for the dairy cattle up to the present decades, according to reports from local family farmers. In recent years, despite important advances in the management of soil chemical fertility and pasture management through the introduction of forage species, there has been a lack of interest among the farmers, heirs to these lands, regarding these advances. Simultaneously, there is a growing dependence on external sources for livestock feeding supplementation within the productive units. Difficulties related to seasonality in forage production and the lack of information about the importance of proper corrective and fertilizer management contribute to pasture degradation and subsequent soil exposure to erosive processes, putting farmers in a vulnerable situation, which, in some cases, leads to the abandonment of livestock activities and even agricultural production units. In this scenario, this study aimed to evaluate, in a participatory manner through a case study, the phytotechnical performance of the forage species Avena strigosa (black oat), Avena sativa (white oat), Vicia sativa (common vetch), and Raphanus sativus (forage radish), both in monoculture and in intercropping. Additionally, it aimed to assess the benefits of correcting soil acidity and fertilization with different sources, organic and synthetic, on the establishment of these forage species. To achieve this, observational plots were established, and the stages of installation, monitoring, and data collection involved active participation from neighboring farmers.The observed results indicate that the adopted participatory methodologies, based on action research, stimulated the involvement of farmers in the different stages of the work, making it possible to verify collective and individual reflections regarding the aspects of soil chemical fertility management, as well as the introduced forage species. Concerning the phytotechnical performance of the species, black oat, white oat, and forage radish showed characteristics such as rapid soil coverage and good potential for fresh and dry mass productivity in plots that received limestone and fertilizers. On the other hand, common vetch had a less desirable establishment, even in the presence of acidity correction and fertilization. Thus, it was possible to conclude in this case study that correcting soil acidity and fertilization are essential tools for the management of soil chemical fertility necessary for the adequate development of winter forage species, except for common vetch, sown under the edaphoclimatic conditions of the Ribeirão das Furnas micro-watershed in Aiuruoca, Minas Gerais.
