What is BS EN 13654-1 - Nitrogen in soil improvers and growing media about?
BS EN 13654-1 is a standard that serves technical specifications for determining nitrogen in soil improvers and growing media, ensuring the inclusion of naturally slow-releasing nitrogen in soil improvers and growing media.
BS EN 13654-1 specifies a method for the determination of nitrogen in soil improvers and growing media. The Kjeldahl method determines ammonium-N, nitrate-N, nitrite-N and organic N content of soil improvers and growing media. Nitrogen in N-N-linkages, N-O-linkages and some heterocyclics (especially pyridine) is only partially determined.
Note: BS EN 13654-1 is not applicable to liming materials and preformed materials such as mineral wool slabs and foam slabs.
Who is BS EN 13654-1 - Nitrogen in soil improvers and growing media for?
BS EN 13654-1 on nitrogen in soil improvers and growing media applies to:
- Manufacturers of soil improvers and growing media
- Testing houses and labs for soil improvers and growing media
- Quality assurance services
- Research and development departments
- Soil inspection services
Why should you use BS EN 13654-1 - Nitrogen in soil improvers and growing media?
Soil improvers are substrates that help to improve the structure and fertility of the soil. Soil improvers are mixed into the top layer of the garden, in the root zone of the plants. Growing media are mixes of components that give plants water, air, nutrients, and support. The nitrogen content is determined using a method based on sulfuric acid/potassium sulfate digestion.
BS EN 13654-1 provides users guidance on the Kjeldahl method for the determination of nitrogen in soil improvers and growing media. BS EN 13654-1 also provides users with a step-by-step procedure for the method, enabling users to do the method correctly.
BS EN 13654-1 provides users guidance on principle, reagents, apparatus, test sample, procedure, calculation, expression of results, precision, and test report, enabling accurate detection and identification of nitrogen which increases root growth and foraging capacity for phosphorus.
With obedience and compliance to BS EN 13654-1, users can determine nitrogen content, enabling microbial nitrogen conversion and prevention of depleting nitrogen from soil improvers and growing media.
