Introduction
Throughout the member countries of CEN, regular liming to regulate the soil pH level and to neutralize
the effect of soil acidification is a well-established and essential agricultural operation on all soils in
humid climates and under all systems of agricultural cultivation. Liming improves soil fertility and
supplies essential plant nutrients.
Liming materials are also used in forest liming, lake liming and the liming of water catchment areas.
A wide range of natural geological deposits of liming materials is found in all member countries of CEN.
Some industrial processes produce materials acceptable as liming products. This very wide range of
material differs substantially in both chemical and physical properties. The use of these various materials
will vary according to the type of material.
However, for the purpose of comparison of these products, it is relevant to describe and specify the
minimum requirements of a liming material.
NOTE Regulation (EU) 2019/1009 [1], which replaces Regulation (EC) No 2003/2003 [2] and has an
accompanying communication on visual aspects of labels [3] that allows to refer to denominations (type
designations) of this standard in the label section “additional information”, has been used as a source for this
document.
Liming materials in Europe show a large diversity due to factors as climate and type of crops, production,
transport, storing and spreading of lime adapted to regional conditions. Standard quality covers these
varying liming materials, whilst fine quality credits rapidly dissolving materials needed for certain
specialized agricultural productions or to allow the dissolution of the liming material in some soil types
having a higher pH value in a rapid and controlled way.
1 Scope
This document describes and specifies the requirements of products of natural origin and products from
industrial processes of basic and fine quality to be used as liming materials in agriculture for raising the
pH of soil (and water).

4 Denominations and specifications for liming materials
The denominations (type designations), specifications and elements to be declared are specified in
Table 1 to Table 6 as follows:
— Table 1: Natural limes;
— Table 2: Oxide and hydroxide limes of natural origin;
— Table 3: Limes from industrial processes;
— Table 4: Silicate limes;
— Table 5: Mixed limes;
— Table 6: Mixtures of liming materials with other fertilizing products.
NOTE 1 Regarding limits to contaminants, EU or local regulations and requirements can apply.
Granulated liming materials which are produced by aggregating smaller primary particles shall break
down when stirred in water into particles with fineness distributions as specified in the type descriptions,
and as measured using the method specified in EN 15704.
All the properties mentioned in the Table 1 to Table 6 refer to the product as supplied unless otherwise
specified.
-
All the neutralizing requirements are expressed as CaO-equivalent and as HO -equivalent in brackets.
NOTE 2 For mixed limes other than specified in Table 5, EU or local regulations and requirements for agricultural
liming materials can apply.
For products obtained by mixing, the type designation shall be completed by the list of the components
with the maximum of three types.
In case of mixtures of raw materials containing dolomite for common grinding, the final mixed product
shall be finer than 97 % at 1,5 mm.
