Livestock-crop integration effects on physical attributes of a soil under no-till
01/Feb/2009
Soil physical characteristics were evaluated of a typical dystrophic Red Latosol (Typic Haplorthox) located in Passo Fundo, State of Rio Grande do Sul, Brazil, after ten years (1993 to 2003) under mixed production systems. The effects of production systems integrating grain production with winter annual and perennial forages under no-tillage were assessed. Five mixed cropping systems were evaluated: I) wheat/soybean, white oat/soybean, and common vetch/corn; II) wheat/soybean, white oat/soybean, and annual forages (black oat + common vetch)/corn; III) perennial cool […]
Effect of mixed crop production systems under no-tillage on soil fertility after eight years
01/Jun/2003
Soil fertility characteristics were evaluated on a typical dystrophic Red Latosol (Typic Haplorthox) located in Passo Fundo, State of Rio Grande do Sul, Brazil, after eight years of use under mixed production systems (1993 to 2000). The effects of production systems integrating grain production with winter annual and perennial pastures under no-tillage were assessed. Four production systems were evaluated: system I (wheat/soybean, white oat/soybean, and common vetch/corn); system II (wheat/soybean, white oat/soybean, and grazed black oat + grazed common vetch/corn); system III [perennial […]
