Author(s):McCallum, K. J.; Rennie, D. A.; Paul, Eldor A.; Campbell, C. A.
Date Issued:1967-08
Format:born digital; articles
Factors affecting the accuracy of the carbon-dating method of analysis have been discussed by several workers (1, 3, 13, 14). Since, however, these workers were interested primarily in archeological and geological applications ...
Applicability of the carbon-dating method of analysis to soil humus studies
Author(s):McCallum, K. J.; Rennie, D. A.; Paul, Eldor A.; Campbell, C. A.
Date Issued:1967-09
Format:born digital; articles
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 ...

Author(s):Rennie, D. A.; Campbell, C. A.; Paul, Eldor A.; McCallum, K. J.
Date Issued:1964
Format:born digital; articles
The radioactivity of naturally occurring C14 in soil humus when compared to the C14 activity of a standard of recent origin (carbon dating) can be used to estimate the mean residence time of the soil humus in studying ...
