This European Standard specifies two methods for the determination of the neutralizing value (NV) of liming materials.<\/p>\n

Method A is applicable to all liming materials except silicate liming materials.<\/p>\n

Method B is applicable to all liming materials.<\/p>\n

Both methods do not correctly take into account the potential neutralizing value of material containing more than 3 % P 2<\/sub>O 5<\/sub>. For a more accurate agronomic assessment of products containing more than 3 % P 2<\/sub>O 5<\/sub> determine the liming efficiency according to EN 14984<\/span> <\/span>.<\/p>\n

\n
\n NOTE\n <\/div>\n

The methods described in ISO 6598<\/span> <\/span> [1]<\/span> and ISO 7497<\/span> <\/span> [2]<\/span> can be used for the determination of P 2<\/sub>O 5<\/sub> content. Further information on P analyses is given in [3]<\/span> and [4]<\/span>.<\/p>\n<\/div>\n
