Standard Method of Test for Determination of Organic Content in Soils by Loss of Ignition
standard by American Association of State and Highway Transportation Officials, 1986



The Loss on Ignition method for the determination of organic content is most applicable to those materials identified as peats, organic mucks, and soils containing relatively undecayed or undecomposed vegetative matter or fresh plant materials such as wood, roots, grass, or carbonaceous materials such as lignite, coal, etc. This method determines the quantitative oxidation of organic matter in these materials and gives a valid estimate of organic content. The Wet Combustion (T 194) method is recommended when it is desired to determine the humus-like easily oxidized organic material to provide information relating to the suitability of a soil for plant growth.
