ASTM D5268-13
Standard Specification for Topsoil Used for Landscaping Purposes
1.1 This specification covers a physical evaluation of an inorganic soil containing a limited amount of organic material, relative to its use as a topsoil for horticultural purposes in construction. For classification, a full agricultural textural classification may be used.
1.2 The presence in the soil of the correct nutrients and pH status is necessary for healthy plant growth. This specification does not, however, cover a determination of the nutrients, nor their availability.2
1.3 Typical general ranges of soil content are presented in Table 1. Soils falling within these ranges will generally form a suitable topsoil. It must, however, be recognized that in some geographic regions, concurrence with the values of Table 1 would be most difficult. In such cases, locally acceptable specifications would need to be developed.
