Resumo: | Soil fertility and yield was evaluated on a typical dystrophic Red Latosol (Typic Haplorthox) located in Passo Fundo, State of Rio Grande do Sul, Brazil, after eight years under mixed production systems (1993 to 2000). Five production systems were evaluated: system I (wheat/soybean, common vetch/corn, and white oat/soybean); system II (wheat/soybean, grazed black oat + grazed common vetch/corn, and white oat/soybean); system III [perennial cool season pastures (fescue + white clover + red clover + birdsfoot trefoil)]; system IV [perennial warm season pastures (bahiagrass + black oat + rye grass + white clover + red clover + birdsfoot trefoil)]; and system V (alfalfa as hay crop), which was established in replicated plots in an adjacent area in 1994. The treatments were arranged in a randomized complete block design, with four replications. Exchangeable Al, exchangeable Ca + Mg, organic matter, extractable P, and exchangeable K levels displayed differences among crop production systems, whereas the production systems raised the corresponding contents, chiefly in the 0-5 cm layer. Organic matter, exchangeable Al, extractable P, and exchangeable K levels decreased from the 0-5 cm soil layer to the 15-20 cm layer, while the opposite occurred with the pH and exchangeable Ca + Mg contents. |

Os atributos de solo relativos à fertilidade química e ao rendimento foram avaliados num Latossolo Vermelho Distrófico típico, em Passo Fundo, RS, oito anos após o estabelecimento (1993 a 2000) dos seguintes sistemas de produção: sistema I (trigo/soja, ervilhaca/milho e aveia branca/soja); sistema II (trigo/soja, pastagem de aveia preta + ervilhaca/milho e aveia branca/soja); sistema III [pastagens perenes de estação fria (festuca + trevo branco + trevo vermelho + cornichão)]; sistema IV [pastagens perenes de estação quente (pensacola + aveia preta + azevém + trevo branco + trevo vermelho + cornichão)]; e sistema V (alfafa para feno), acrescentado como tratamento adicional, sendo repetido, em áreas contíguas ao experimento em 1994. Tratamentos foram distribuídos em blocos ao acaso com quatro repetições. Valores de Al trocável, de Ca + Mg trocáveis, de matéria orgânica, de P extraível e de K trocável diferiram entre os sistemas de produção. Os sistemas de produção elevaram o nível de matéria orgânica e o teor de K trocável, principal- mente na camada de solo 0-5 cm. Os níveis de matéria orgânica e os teores de Al trocável, de P extraível e de K trocável diminuíram da camada 0-5 cm para a camada 15-20 cm, enquanto para os valores de pH e de Ca + Mg trocáveis ocorreu o contrário.Departamento de Diagnóstico e Pesquisa Agropecuária.
