土壤土是土壤有机质(SOM)具有独特垂直分布的土壤。我们假设，土壤化作为一种土壤发生过程，影响甚至控制着土壤有机质的内容、分配和质量。测定了土壤化程度不同的五种土壤矿物层中有机碳和氮的含量。这五种土壤是：沙粒和稳定团聚体(S+A)、颗粒状有机质(POM)和颗粒状有机质(GT；63微米)。
Podzols are soils that display a unique vertical distribution of soil organic matter (SOM). We hypothesise that podzolisation, as a pedogenetic process, influences or even controls content, allocation and quality of SOM. We determined soil organic carbon (SOC) and nitrogen (N) contents in six SOM fractions obtained from mineral horizons of five soils with increasing degree of podzolisation: sand and stable aggregates (S + A), particulate organic matter (POM) > 63 mu m and
