It is felt that FAO should take the lead to make suggestions and propositions for obtaining a certain harmonisation of methods on a regional basis. Therefore this booklet contains a choice of analytical methods, which have been applied in various conditions and which were judiciously selected. It should be stressed that the actual methods are not an end point in soil testing, even if a good harmonization on a large regional basis could be realized. Though improving and comparing methods is not the normal task of a plant and soil testing service, its participation to programs of sample exchange and common comparative analysis is very useful.
