Publisher version: http://journals.lww.com/soilsci/Citation/1967/09000/APPLICABILITY_OF_THE_CARBON_DATING_METHOD_OF.10.aspx.The organic fraction of soil is known to be composed of the soil biomass, partially decomposed plant and animal residues, and the materials commonly referred to as humic substances. Knowledge of the persistence of these fractions in soil is vital to the understanding of their contribution to soil fertility and soil genesis. Much information concerning the biochemistry of the humus materials also could be obtained through a knowledge of the mean residence times of the various organic fractions.born digitalarticleseng©1987 Williams and Wilkins Co..Copyright and other restrictions may apply.
