Nutrient content in manure

11.4.2014 1

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
