BS EN 13650:2001

What is BS EN 13650 - Extraction of aqua regia soluble elements in soil improvers and growing media about? 

BS EN 13650 is a standard that serves technical specifications for the extraction of aqua regia soluble elements in soil improvers and growing media, to determine the quality and efficiency of soil improvers and growing media in agricultural applications. 

BS EN 13650 specifies a method for the routine extraction of aqua regia soluble elements from soil improvers or growing media. Materials containing more than about 28 % (m/m) organic matter will require treatment with additional nitric acid. With high solute concentrations in extract solutions, spectral interference and background enhancement should be expected. 

Note: The BS EN 13650 method is not applicable to liming materials and preformed materials such as mineral wool slabs and foam slabs. 

Who is BS EN 13650 - Extraction of aqua regia soluble elements in soil improvers and growing media for? 

BS EN 13650 on the extraction of aqua regia soluble elements in soil improvers and growing media applies to: 

• Manufacturers of soil improvers and growing media 
• Testing houses and labs for soil improvers and growing media 
• Quality assurance services 
• Research and development departments 
• Soil inspection services 

Why should you use BS EN 13650 - Extraction of aqua regia soluble elements in soil improvers and growing media? 

Soil improvers are substrates that help to improve the structure and fertility of the soil. Soil improvers are mixed into the top layer of the garden, in the root zone of the plants. Growing media are mixes of components that give plants water, air, nutrients, and support. 

BS EN 13650 provides users guidance on a method for the routine extraction of aqua regia soluble elements from soil improvers or growing media. BS EN 13650 also provides users with a step-by-step procedure for the method, enabling users to do the method correctly. 

BS EN 13650 provides users guidance on principle, reagents, apparatus, test sample passing through a 500 µm sieve, procedure, determination of extracted elements, expression of results, precision, and test report, enabling accuracy in the extraction of aqua regia soluble elements. 

BS EN 13650 provides users information in a tabular form for soluble elements in composted bark, bio waste, clay peat, coarse peat, composted sludge, and more for further analysis and determination of elements such as phosphorus, potassium, calcium and more. 

With obedience and compliance to BS EN 13650, users can extract aqua regia soluble elements, enabling the detection of micronutrients and heavy metals to determine the efficiency, quality and longevity of soil improvers and growing media.
