Two optional procedures are also given, describing respectively, determinations of free H<sup>+<\/sup> acidity and of aluminium in the extracts.<\/p>\n<p>This International Standard is applicable to all types of air-dry soil samples which have been pretreated in accordance with ISO 11464.<\/p>\n<blockquote>\n<p>NOTE Titration of exchangeable acidity by means of a fixed-pH end-point may not be specific to a given acid species. The end-point pH value retained is 7,8, corresponding to complete precipitation of Al<sup>+3<\/sup> ions in synthetic solutions. Titration of soil extracts to this pH may also include some more weakly ionized species or weak acid organic compounds.<\/p>\n<\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p><b>Soil quality.
