Abstract
A method is presented for determining organic C content of soils, extracts and plant tissue utilizing an acidic wet oxidation in modified culture tubes; samples containing carbonates are pretreated with dilute acid. Evolved CO2 is trapped in a NaOH solution and quantified titrimetrically. The method described has a range of 0.4-11 mg C and the range can be extended in either direction by modifying the CO2 trapping/titration procedure. This method is as accurate and precise as more time consuming dry oxidation procedures.Keywords
