Soil quality. Extraction of trace elements from soil using ammonium nitrate solutionBS ISO 19730: 2008 Soil quality. Extraction of trace elements from soil using ammonium nitrate solution BS ISO 19730 specifies a method of extracting trace elements from soil using a 1 mol l NH4NO3 Solution. In conjunction with extraction methods for determining the reserves of elements in soil (e. g. extraction with aqua regia), the proportions by mass determined by extraction with ammonium nitrate solution can serve as a basis for site
