Abstract

This specification covers the physical evaluation of an inorganic soil containing a limited amount of organic material, relative to its use as topsoil for landscaping and horticultural purposes in construction. Though the presence of the correct nutrients and pH status in the soil is necessary for healthy plant growth, this specification, however, does not address either the determination or the availability of such properties. When physically evaluating soil relative to its suitability to support plant growth (primarily grasses), tests must be made to determine the presence and the amount of organic matter, inorganic matter (sand, silt, and clay), and deleterious materials (rocks, gravel, slag, cinder, roots, and sod). The apparatuses required here are sieves and containers, balances, and a muffle furnace.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

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. Note 1 - The nutrient content of topsoil is important and the nutrients usually evaluated are nitrogen, phosphate, and potassium. Nutrient deficiencies may be corrected using organic or inorganic fertilizers. Excess soluble salts should be examined as to their desirability. The acidity or alkalinity of the soil is also important. Excess acidity may be corrected by the application of lime. Excess alkalinity may be corrected by the application of sulfur or other suitable acidifying compounds. The latter item, in addition to lowering pH, also could be considered as an aggregate when considering the particle size distribution.

1.3 The values stated in SI units are to be regarded as the standard.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
