A Thermogravimetric Approach to the Classification of Organic Soils1
- M. Schnitzer and
- I. Hoffman2
The thermogravimetric method is shown to offer a simple but valid and meaningful method for assessing the degree of humification of organic soils. Heights of the 280C maxima in the differential thermogravimetric (DTG) curves of 22 organic soil samples, ranging from peats, mucky peats, peaty mucks to mucks, were inversely proportional to the degree of humification as determined by pyrophosphate solubility. Highly significant negative correlations were found between peak height at 280C and (i) solubility in 0.025
