Plain language summary
Concentrations of carbon in archived soil samples are reported for a long-term experiment established more than a century ago. These data will be useful for testing carbon simulation models.
Abstract
Soil organic carbon (SOC) changes slowly, and final management influences can be measured only after decades. Analysis of archived samples from a site established on grassland in 1911 showed that SOC, under wheat systems, approached steady state after several decades, and that its amount reflected the inputs of residue C.
