Background
40 reduction of N-fertiliser use (with
simultaneous increase in crop yields!!)

Background
Satellite picture of EU seas chlorophyll-a
concentrations. Average summer 2000. The red and
yellow areas show strong phyto-plancton
develop-ment, one of the most visible symptoms of
eutrophication, with potential adverse effects
(toxic dinoflagel-lates, oxygen depletion,
changes in bottom flora and fauna, etc).
5
Background
Nitrogen balance from 2005 at 8 Serbian farms.
The farm with a balance of 305 kg nitrogen per
ha has an area of 100 ha, meaning that the farm
pollutes the environment with 30,500 kg nitrogen
per year. This is not only a problem for the
environment as nitrogen has a value of 0.7 per
kg (calculated on basis of the price of nitrogen
fertiliser) it means that the farmer looses
21,000 per year in just nitrogen loss.

Requirements to fertiliser planning

• Limitation of the land application of
  fertilizers
• soil conditions, soil type and slope
• climatic conditions, rainfall and irrigation
• land use and agricultural practices, including
  crop rotation systems, and to be based on a
  balance between
• the foreseeable nitrogen requirements of the
  crops,
• the nitrogen supply to the crops from the soil
  and from fertilization.

12
Requirements to fertiliser planning

• Shall ensure that, for each farm or livestock
  unit, the amount of livestock manure applied to
  the land each year, including by the animals
  themselves, shall not exceed a specified amount
  per hectare.
• The specified amount per hectare be the amount of
  manure containing 170 kg N. However
• for the first four year action programme Member
  States may allow an amount of manure containing
  up to 210 kg N
• during and after the first four-year action
  programme, Member States may fix different
  amounts from those referred to above. These
  amounts must be fixed so as not to prejudice the
  achievement of the objectives specified in
  Article 1 and must be justified on the basis of
  objectives criteria.

13
Requirements to fertiliser planning

• EU procedure for fertiliser planning
• Calculation of the needs of the crop
• Reduction with the plant nutrients in distributed
  livestock manure
• Fulfiling the rest of the norms with mineral
  fertiliser
