What is BS EN 16357 - Determination of reactivity in liming materials about?
BS EN 16357 is a standard that serves technical specifications for the determination of reactivity in liming materials, enabling control of soil acidity and improving water penetration in acidic soils.
BS EN 16357 specifies a method for the determination of the reactivity of calcium carbonate and calcium magnesium carbonate liming materials.
BS EN 16357 assesses the speed and effectiveness of their neutralising potential by automatic titration with citric acid.
BS EN 16357 is applicable only to liming materials with a maximum particle size of 6.3 mm determined according to EN 12948.
Who is BS EN 16357 - Determination of reactivity in liming materials for?
BS EN 16357 on the determination of reactivity in liming materials applies to:
- Manufacturers of liming materials for agricultural applications
- Dealers and importers of liming materials for agricultural applications
- Testing houses and labs for liming materials
- Soil inspection services
Why should you use BS EN 16357 - Determination of reactivity in liming materials?
The efficiency of a liming substance in agricultural use is determined by its neutralising value, grinding fineness, reactivity, and the parent rock's relative hardness. The reactivity Test is the measure of the effectiveness and speed of reaction of liming material. The findings of this test can be used to predict how a liming substance will impact the soil.
BS EN 16357 provides users guidance on the automatic titration method for the determination of reactivity of carbonate liming materials. BS EN 16357 also provides users with a step-by-step procedure for the method, enabling users to do the method correctly.
BS EN 16357 provides users guidance on principle, apparatus, reagents, sampling, sample preparation, procedure, calculation, expression of results, precision and test report, enabling the measurement of the effectiveness of lime.
With obedience and compliance to BS EN 16357, users can assess the efficiency of liming materials, ensuring the improvement in soil structure and increase in microbial activity for optimum plant growth.
