This workshop on best practices in soil preparation was provided in cooperation with the Instituto Nacional de Tecnologia Agropecuaria (INTA) and the Instituto Nacional de la Agricultura Familiar, Campesina e Indígena (INAFCI). The farmers engaged by the project – all from a small village called Paraje Alegria just to the south-east of Cruce Caballero Provincial Park – were the target audience, but these sessions were open to anyone, and the average participation was 35 people. To prepare their yerba mate plots, the farmers receive supplies from the project – lime, fertilizer and seedlings – as well as support from INTA and INAFCI technicians to define the best ground cover species, aiming to reduce the use of herbicides.
