Carbon and nitrogen in the particle size fractions of soil organic matter in crop systems under no-tillage
01/Jun/2014
Soil quality in no-till systems is related to the crop systems and may be evaluated through particulate organic matter (>53 ∝m) stock due to the functionality this property provides to the soil and its sensitivity to management practices. Aiming to assess soil quality no-till crop systems, this study was carried out through a long-term experiment (21 years) in a Latossolo Vermelho distrófico típico (typical Oxisol) in Ponta Grossa, PR, Brazil. Six crop systems were assessed. Wheat-TR (Triticum aestivum L.), soybean-SO […]
