For this purpose, Member States shall decide what analyses to carry out, taking account of available scientific data on soil characteristics and homogeneity.2.Member States shall decide on the frequency of further analyses, taking account of the metal content of the soil prior to the use of sludge, the quantity and composition of the sludge used and any other relevant factors.3.Analysis should cover the following parameters:pH,cadmium, copper, nickel, lead, zinc, mercury and chromium.ANNEX II CSAMPLING AND ANALYSIS METHODS1.Soil samplingThe representative soil samples for analysis should normally be made up by mixing together 25 core samples taken over an area not exceeding 5 hectares which is farmed for the same purpose.The samples must be taken to a depth of 25 cm unless the depth of the surface soil is less than that value; however, the sampling depth in the latter case must not be less than 10 cm.2.Sludge samplingSludge must be sampled after processing, but before delivery to the user, and should be representative of the sludge production.3.Methods of analysisAnalysis for heavy metals must be carried out following strong acid digestion. The reference method of analysis must be that of atomic absorption spectrometry and the limit of detection for each metal should be no greater than 10 % of the appropriate limit value.
