In a study addressing composition and recovery of soil carbon following pasture installation on arable land, radiocarbon isotope ratios were measured in size- and density-separated soil organic matter (SOM) fractions in a pasture and maize plot. The average soil carbon age increased with depth from 444 yr in the 0-30-cm layer to 2456 yr in the 60-80-cm layer in the pasture soils, and from 42 to 1625 yr in the maize-cultivated soil. Weight fractionation of the macro-organic matter (size &gt;150 mu m) in a light (density 1.37 g cm(-3)) resulted in markedly different ages for different fractions with ages increasing from 2 yr in the light fraction to &gt;3000 yr in the heavy fractions.
