Scope

Nitrogen content is important as it is one of the primary plant food elements necessary for plant growth. Nitrogen is present in peat as organic nitrogen, and therefore, does not release nitrogen to plants as quickly as chemical fertilizers. However, nitrogen from peat continues to be released for several years as the organic matter decomposes.

1.1 This is a chemical test method for the determination of the weight percent of nitrogen in peat material.

1.2 This standard does not purport to address the safety problems 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.
