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% P 2O 5. For a more accurate agronomic assessment of products containing more than 3% P 2O 5 determine the liming efficiency according to EN14984 . NOTE The methods described in ISO6598 [1] and ISO7497 [2] can be used for the determination of P 2O 5 content. Further information on P analyses is given in [3] and [4].
