Resumo

This study aimed to evaluate the effects of different soil management systems on soybean yield and soil quality indicators in a dystrophic Red Latosol in the municipality of Tiradentes do Sul, RS, Brazil. Two areas under no-tillage system were compared: one with crop rotation and cover crops (corn, radish, wheat, and a mix of cover species), and another conducted under the traditional soybean-wheat system with winter fallow. Soil physical and chemical variables, grain yield, and weed occurrence were analyzed. The results indicated that the use of cover crops improved soil pH, increased dry matter and organic matter input, and resulted in a 1,320 kg ha-¹ increase in soybean productivity. It is concluded that the use of cover crops and crop diversification is more efficient for soil conservation and increasing soybean yield.
