AASHTO T194

Standard Method of Test for Determination of Organic Matter in Soils by Wet Combustion

Applicability: AASHTO T194 is a standard test method used to determine the organic matter content of soils, specifically focusing on the humus-like, easily oxidized organic material.

Purpose: This information is particularly useful for assessing the suitability of soil for plant growth, as this type of organic matter plays a vital role in soil fertility and structure. The method is particularly useful for soils where this type of organic matter is dominant.
