Abstract
The presence of agricultural production in the metropolitan region of Porto Alegre (MRPA) is small but quite significant. This importance has prompted the search for ways of consolidating such activity, especially family farming. With the aim of evaluating soil characteristics and relating them to the perceptions and appraisal of the local farmers, two settlements in the MRPA were visited, where areas of housing and family production were chosen for this study. Resources, such as semi-structured interviews, hiking and the selection of tracts of farmland for soil sampling and monitoring were used. The results showed that the soils have some limitations on use, such as the sandy texture, low natural fertility and, in some areas, restricted drainage. Local settlers can distinguish between these characteristics, and to do this, a comparison with the soils of their places of origin was important. The people displayed greater familiarity with field-based approaches, showing these to be the most productive forms of dialogue with technicians and researchers. Similarities were noted between several observations made by the public and the criteria and technical and scientific attributes used in surveys and in evaluating land suitability, showing a correspondence between these different forms of learning, and making it feasible to plan sustainable production systems on a participatory basis.
