What is BS EN 15688 - Urease inhibitor NBPT in fertilizers about?
BS EN 15688 is a standard that serves technical specifications for the determination of urease inhibitor NBPT in fertilizers to control or reduce gaseous losses of nitrogen after fertilization with urea.
BS EN 15688 specifies a method for the quantitative determination of the urease inhibitor N-(nbutyl)thiophosphoric triamide (NBPT) content in water-soluble matrices, i.e. urea-based fertilizers using high performance liquid chromatography (HPLC).
Note: Pure NBPT reference material is required as a standard for quantitative calibration.
Who is BS EN 15688 - Urease inhibitor NBPT in fertilizers for?
BS EN 15688 on the determination of urease inhibitor NBPT in fertilizers applies to:
- Manufacturers of fertilizers
- Dealers and importers of fertilizers
- Testing labs for fertilizers
- Quality assurance services
- Regulatory bodies
- Soil inspection services
Why should you use BS EN 15688 - Urease inhibitor NBPT in fertilizers?
NBPT is a urease inhibitor that enhances the efficiency of fertilizers and limits the release of nitrogen-containing gases. In agricultural applications, NBPT reduces ammonia volatilization loss and enhances nitrogen availability to plants.
BS EN 15688 provides users guidance on the High Performance Liquid Chromatography (HPLC) method for determining urease inhibitor N-(nbutyl)thiophosphoric triamide (NBPT) content in fertilizers. BS EN 15688 also provides users with a step-by-step procedure for the method, enabling users to do the method accurately.
BS EN 15688 provides users guidance on principle, reagents, apparatus, sampling, sample preparation, procedure, calculation, expression of result, precision and test report, for the accurate determination of urease inhibitor in fertilizers.
With obedience and compliance to BS EN 15688, users can slow urea hydrolysis, reduce ammonia volatilization loss, and enhances nitrogen availability to plants.
