[font size=3]ANN ARBOR—Surface appearances can be so misleading: In most forests, the amount of carbon held in soils is substantially greater than the amount contained in the trees themselves.
…
In a paper published online April 1 in the Soil Science Society of America Journal, they looked at lands previously used for surface mining and other industrial processes, former agricultural lands and native grasslands where forests have encroached.
U-M ecologist Luke Nave and his colleagues found that, in general, growing trees on formerly nonforested land increases soil carbon. Previous studies have been equivocal about the effects of so-called afforestation on soil carbon levels.
"Collectively, these results demonstrate that planting trees or allowing them to establish naturally on nonforested lands has a significant, positive effect on the amount of carbon held in soils," said Nave, an assistant research scientist at the U-M Biological Station and in the Department of Ecology and Evolutionary Biology.
