This International Standard specifies an extraction method and analytical conditions to determine the content of soil phosphorus soluble in sodium hydrogen carbonate solution. After the extraction step, two different methods of colour development are possible. Subclause 4.2 specifies colour development at room temperature. Subclause 4.3 specifies colour development after heating to a high temperature. This International Standard is applicable to all types of soils.
