Resumo: Small family farms constitute a major part of land use in the surrounding regions of Brazilian cities, as these farms not only contribute to the food supply, but also help conserve rural landscapes and improve environmental services. This study evaluated agricultural impacts on soil quality in seven family farms in Porto Alegre municipality, Rio Grande do Sul state, RS. Selected production units (PUs) were managed as conventional or organic farms, producing horticultural crops, fruits and pastures, besides native forests. Soil samples were collected from representative areas for five use and management types, under disturbed and undisturbed conditions, at 0–20 cm depth. Physical and chemical attributes were analyzed, comparing the effects of types of land use. Data analysis showed that more affected attributes were soil density, macro and microporosity, phosphorus content, pH and electrical conductivity. Macroporosity, phosphorus, zinc and cooper contents are the greater threats to soil quality. Horticulture, under both agroecological and conventional production systems caused major changes compared to natural conditions.

Este estudo teve como objetivo avaliar os impactos agrícolas na qualidade do solo em sete propriedades sob forma de produção familiar em Porto Alegre, estado do Rio Grande do Sul. As unidades de produção (PUs) selecionadas eram trabalhadas sob produção convencional ou orgânica, com culturas hortícolas, frutas e pastagens, além de floresta nativa. Amostras de solo foram coletadas em áreas representativas de cinco formas de uso e manejo do solo, em condições deformada e indeformada, na profundidade 0 a 20 cm. Atributos físicos e químicos de solo foram analisados, comparando os efeitos dos tipos de uso da terra. A análise dos dados mostrou que atributos mais afetados pela mudança no uso da terra foram densidade, microporosidade, macroporosidade, conteúdo de fósforo, pH e condutividade elétrica. Macroporosidade, teores de fósforo, zinco e cobre parecem ser as maiores ameaças à qualidade do solo. A horticultura, tanto no sistema convencional como no orgânico, causou as maiores alterações em relação à condição original.Departamento de Diagnóstico e Pesquisa Agropecuária.
