What is BS EN 15959 - Determination of extracted phosphorus in fertilizers about?
BS EN 15959 is a European standard that serves technical specifications for the determination of extracted phosphorus in fertilizers, enabling the determination of phosphorus content in fertilizers for increased crop yields in agricultural applications. BS EN 15959 specifies a method for the determination of phosphorus in fertilizer extracts.
BS EN 15959 method is applicable to all extracts of fertilizers for the determination of the different forms of phosphorus as phosphorus soluble in mineral acids, water soluble phosphorus, phosphorus soluble in solutions of ammonium citrate, phosphorus soluble in 2 % citric acid and phosphorus soluble in 2 % formic acid.
Who is BS EN 15959 - Determination of extracted phosphorus in fertilizers for?
BS EN 15959 on the determination of extracted phosphorus in fertilizers applies to:
- Manufacturers of fertilizers
- Dealers and importers of fertilizers
- Testing labs for fertilizers
- Safety assurance services
- Regulatory bodies
Why should you use BS EN 15959 - Determination of extracted phosphorus in fertilizers?
Phosphorus is a vital nutrient in plants. It is a component of several major plant structural compounds and catalyses the conversion of many vital biochemical reactions. In agricultural applications, the extraction of phosphorus is used to improve the prediction of fertilizer phosphorus availability to plants.
BS EN 15959 provides users guidance on a method for the determination of extracted phosphorus in fertilizers. BS EN 15959 also provides users with a step-by-step procedure for the method, enabling users to do the method correctly.
BS EN 15959 provides users guidance on principle, sampling, sample preparation, reagents, apparatus, procedure, calculation, expression of results, precision, and test report, enabling the accurate determination of extracted phosphorus.
With obedience and compliance of BS EN 15959, users can assess the uniformity of phosphorous and nutrient availability in fertilizers, enabling users to treat and prevent phosphorous deficiency in plants for increased crop yields.
