ASTM D5715

Estimating the Degree of Humification of Peat and Other Organic Soils (Visual/Manual Method)

Applicability: ASTM D5715 is a standard for estimating the degree of humification of peat and other organic soils using a visual/manual method. It is applicable to peat and other organic soils, but may not be suitable for all types of soil, especially those with high moisture or dissolved solids content, or certain mineral types like halloysite.

Purpose: The purpose of ASTM D5715 is to provide a standardized visual/manual method for estimating the degree of humification of peat and other organic soils. This allows for consistent description and classification of these soils for various applications, such as peatland inventories and resource evaluations.
