This standard 25/30478147 DC BS EN 13650 Soil improvers and growing media - Digestion by aqua regia for subsequent determination of elements is classified in these ICS categories:
  • 65.080 Fertilizers
This document specifies a method for the digestion of soil improvers and growing media using an aqua regia digestion. 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 interferences and background enhancement should be expected.
