Standard Test Method for Total Nitrogen in Peat Materials
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
:
1.1 This test method covers a chemical test method for the determination of the weight percent of nitrogen in peat material.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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. (See Practice D3740)
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.
