摘要：

The fate of plant carbon into molecular organic substances form soils can be followed by stable carbon analysis. Soil organic matter thus has been progressively labelled with C-13 at natural abundance by cultivation of Zea mays, a C-4 plant, on a soil which was previously under isotopically distinct C-3 vegetation. The molar carbon percentage of maize n-hentriacontane within soil n-hentriacontane has been calculated by isotopic means and amounts to around 50% after 23 years of maize cultivation.
