What is ISO 20620 - Fertilizers and soil conditioners nitrogen content about?
ISO 20620 specifies a method for the determination of total nitrogen content in all nitrogen-containing fertilizers by combustion method.
NOTE 1: The presence of non-nutritive sources of nitrogen (e.g., chelating agents) causes positive bias to samples being analyzed for nutritive nitrogen content. The non-nutritive nitrogen content is subtracted from the total nitrogen value to determine the nutritive nitrogen content.
NOTE 2: Common internationally traded fertilizers were evaluated for total nitrogen by combustion analysis in the ring-study in this document. While the fertilizers analyzed in this international ring study were mineral fertilizers, previous studies have shown that total nitrogen by combustion is suitable for use with many non-mineral, nitrogen-containing fertilizers.
Who is ISO 20620 - Fertilizers and soil conditioners nitrogen content for?
ISO 20620 on Fertilizers and soil conditioners nitrogen content is useful for:
- Fertilizers and soil conditioners manufacturer
- Dealers and suppliers for Fertilizers and soil conditioners
- Importers of Fertilizers and soil conditioner
- Testing laboratories
Why should you use ISO 20620 - Fertilizers and soil conditioners nitrogen content?
Fertilizers play an important role in providing crops with the nutrients they need to grow and be harvested for nutritious food.
The principal of ISO 20620 states that the presence of non-nutritive sources of nitrogen (e.g., chelating agents) causes positive bias to samples being analyzed for nutritive nitrogen content so non-nutritive nitrogen content is subtracted from the total nitrogen value to determine the nutritive nitrogen content.
Enhance the quality of Fertilizers and soil conditioners with ISO 20620 which provides you a method for the determination of total nitrogen content in all nitrogen-containing fertilizers by combustion method.
