BS EN 14984:2016

This standard BS EN 14984:2016 Liming materials. Determination of product effect on soil pH. Soil incubation method is classified in these ICS categories:

• 65.080 Fertilizers

This document specifies two methods (method A and method B) of measuring the effect of the addition of any material claimed to have a liming effect on the soil, using the same basic principles.

Method A measures the changes to the soil pH resulting from the addition of any material claimed to have a liming effect on a standard soil, measured over a period of one month.

Method B assesses the efficiency of any material claimed to have a liming effect, using a range of defined soils and measured over a period of up to 2,5 years.

The methods are not applicable to mineral products coarser than 6,3 mm for method A or 20 mm for method B, determined according to EN 12948.

NOTE These methods allow comparison of products under controlled climatic conditions but do not replace field experiments.
