Nutrient content in manure

  • Standards/balances
  • Calculated from feeding and production leading to

exctretion in manure

  • Good for regulations
  • Analysis
  • Manure sampled before the application
  • Shows the effect of specific conditions, like feeding, litter,

use of water, ammonia losses etc.

  • Good for fertiliser planning, not so good for regulations

Eurostat activity

  • Meeting in the end of March
  • Material, Intro in CIRCA , address
  • NP excretion figures should be comparable between the

states, when used in nutrient balance calculations etc.

  • Current state of factors
  • Recommendations, how to calculate?
  • Databases…
  • Agrotechnology atlas
  • Reports and projects
  • Baltic manure
  • Database (analysis)

Situation in Finland

  • Manure analysis made every 5th year (Nitrate decree)
  • Statistics collected for the main manure types
  • Table values available
  • Excretion values calculated based on feeding and production

by animal production scientists for the purposes of greenhouse gas emissions, nutrient balances and environmental permits

  • New project started on this spring for developing the manure

nutrient content calculation (Sari Luostarinen et al., funded by Finnish Ministry of Environment)

Situations in other countries

  • Denmark
  • Detailed handbook of manure nutrient contents based on feeding,

production, stables, storage, field applications etc.

  • No analysis used for control or regulations
