Standard Test Method for Total Nitrogen in Peat Materials (Withdrawn 2009)
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
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.
Significance and Use
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.
