ANNEX K: KEY ELEMENTS OF DANISH LEGISLATION
IN RELATION TO N AND P LEACHING
Policies
Denmark had, due to developments in nitrate levels
of the ground water, already taken decisions in 1985
on policy goals and introduced legislation to implement
these goals. EU’s Nitrates Directive was issued
first six years after, heavily inspired of the instruments
that were already taken into use in Denmark to
reduce leaching:
• relation between the livestock manure production
and the agricultural land;
• required storage capacity for livestock manure; and
• restrictions on spreading time for livestock manures.
In order to ease the introduction of the regulations
in a pedagogic and understandable way there was
defined a so-called Animal Unit, by which it without
respect to animal type, feed intensity, production
system, bedding type or other is possible to precisely
define the requirement to the relation between
agricultural land and the livestock production. 1
Animal Unit was determined to 100 kg N ex. storage,
and shall not be mixed with other conversion factors
for livestock, for instance the Large Livestock Units,
which most countries uses, and where 1 cow is 1
Large Livestock Unit, but which has no connection
to the environmental load of the livestock.
The policy plans during the years in relation to
leaching is seen from the table below.
The latest policy plan is the “Green Growth Plan”,
which has been issued by the Danish Government
in April 2009. The plan sets the goal of reducing the
leaching with 210.000 ton N and 19.000 ton P latest
Year Plan Significant elements in legislation:
1985 NPO-plan
- regulation of allowed animal units per ha
- min. storage capacity for animal manure
1987 Water Environment Action Plan I
- 50% reduction in N-leaching from agr.
- 65% ”autumn green fields”
- Slurry in autumn only to winter covered fields
- Slurry only to grass or oilseed rape in autumn
1992 Sustainable agriculture
- Max. N-standards for crops (N-quota per farm)
- Min. utilization of N in animal manure
- Fertiliser plans and -accounts.
1998 Water Environment Action Plan II
- 10% decrease of N-standards (The N-quota)
- 6% ”super” green fields in autumn
- 15% higher utilization of N in animal manure
2005 Water Environment Action Plan III
- 50% reduction of the P leaching
- 13% reduction of the N leaching
