WebThe organic matter of soils is generally determined by converting it to carbon dioxide by means of moist and dry combustion. The carbon dioxide thus evolved is then calculated to organic matter by the use of a conventional factor, 0.471. It has been found, however, that the percentage of carbon in the organic matter of soils varies widely. WebOver the last decade, the annual rate of C transported by rivers globally to the oceans (1.06 Pg C yr −1; 1 Pg = 10 15 g) [ 16] is on the same order of magnitude as the rate of C sequestration by land (3.4 ± 0.9 Pg C y −1) or than the oceanic uptake of atmospheric CO 2 (2.5 ± 0.6 Pg C yr −1) [ 17 ].
