Background

• Project in 1998 / 1999 undertaken by Danish
  Agricultural Advisory Service in cooperation with
  Latvia Agricultural University
• Main financing from Danish Environmental
  Protection Agency
• Wish from Latvian side that the CGAP is wider
  than required by the Nitrate Directive
• 7 chapters Plant production, Livestock
  production, Livestock manure, Plant protection,
  Water resources, Agricultural production systems,
  Bio-diversity and nature

5
Background

• 7 work groups with around 50 experts from 10
  different institutions representing authorities,
  farmers organisation, advice, research, and
  education formulated the codes - this ensured
  that agricultural and environmental interests
  were balanced and the codes were prepared after a
  participatory approach
• The management involved institutions approved the
  final formulations in a letter to the project
• Ministries of agriculture and environment adopted
  the CGAP in June 1999.

• The most important part of the CGAP is the manure
  standard, Table 8 page 27, and the connected
  Table 13 with coefficients for Animal Units
• It was defined that 1 Animal Unit the number
  of animals that produce an amount of manure
  equivalent to 100 kilo N ex storage.
• The biggest challenge was to make Latvian experts
  aware of the relation between
• Fertiliser planning (Kg N, P2O5 and K2O in
  livestock manure)
• Manure standards (figures ex. storage)
• Livestock density (max 170 kg N or 1.7 AU per ha)
• Livestock manure storage capacity (cubic metres)
• and that livestock manure must be defined in
  order to know its fertilising value

• Secondly the CGAP contains recommendations on
  fertiliser planning and the procedure for that
• 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

• The CGAP recommends
• No spreading of livestock manure from 15 October
  till 15 March, not on water saturated and frozen
  soils (Code 27), and not on fields with slope of
  more than 10? (Code 25)
• Fertiliser planning (Code 23, 30 and 37), among
  other on basis of soil sampling each 5 years
  (Code 10)
• Threshold of 10 ha
• Max 170 kg N in livestock manure per ha per year
• The CGAP defined in line with decisions in HELCOM
  that the livestock manure storage capacity should
  be minimum 6 months, and slurry 8 months (Code
  49)
• Codes 50-55 deals with the quality, design and
  construction of manure stores

Importance

• The CGAP made the basis for Cabinet Regulation
  531 - Regulations on the protection of waters and
  soil against pollution caused by nitrates from
  agricultural sources
• It is a recommendation for all farms in Latvia

CGAP is not a law but a recommendation for all
farms

For farming in respect of the aquatic
