This European Standard specifies two methods for the determination of the neutralizing value (NV) of liming materials. Method A is applicable to all liming materials except silicate liming materials. Method B is applicable to all liming materials. Both methods do not correctly take into account the potential neutralizing value of material containing more than 3 % P2O5. For a more accurate agronomic assessment of products containing more than 3 % P2O5 determine the liming efficiency according to EN 14984. NOTE The methods described in ISO 6598 and ISO 7497 can be used for the determination of P2O5 content (see [2] and [3]).
