ISO 19747 discusses fertilizers and soil conditioners. ISO 19747 specifies a method for the determination of monosilicic acid concentrations in nonliquid fertilizer materials. Monosilicic acid is reported as silicon (Si).
ISO 19747 extraction method is applicable to the detection of monosilicic acid in nonliquid fertilizer products, blended products, and beneficial substances at silicon (Si) concentrations of 2 to 84 g/kg, with a limit of detection (LOD) of 0.6 g/kg Si, and a limit of quantification (LOQ) of 2 g/kg correlating well with plant uptake.
Note: ISO 19747 does not apply to Liquid silicon fertilizer sources
ISO 19747 on the determination of monosilicic acid in nonliquid fertilizer materials is applicable to:
Beneficial effects from silicon fertility increase include the development of stress tolerance and crop yield. Other benefits from silicon supplements include CO2 sequestration, reductions in metals toxicity and reduced phosphorus run-off while increasing phosphorus use efficiency.
ISO 19747 provides you with a detailed account of the requirements and procedure for an extraction method to determine the monosilicic acid concentration. ISO 19747 also ensures that you perform the method accurately by providing a step-by-step procedure for the method.
The guidance in ISO 19747 enables you to determine monocyclic acid in nonliquid fertilizer materials which helps you to produce quality fertilizers that can give better crop yield to your consumers.
