Livestock manure; production, transport and use; key figures, 1950-2017
Explanation of symbols
Dataset is not available.
This table comprises information about livestock manure production and production of nitrogen and phosphate in manure. It also includes data on excreted nitrogen that evaporates as ammonia and other nitrogen compounds. The use of nitrogen and phosphate in agricultural holdings is calculated from the manure production and the difference between supply and removal of manure. The use of manure is related to the available spreading area based on fertilising standards.
Data available from 1950 to 2017.
Status of the figures:
The 2017 data is provisional; all other data are final.
Changes as of 4 May 2018:

Description topics
- Nitrogen excretion (N)
- Nitrogen excretion
- Nitrogen excretion consists of the excreted amount of nitrogen (N-total) without deduction of gaseous losses of NH3, NO, N2O and N2.
- Gaseous nitrogen losses (N)
- Total emissions of ammonia (NH3), nitrous oxide (N2O), nitric oxide (NO) and nitrogen (N2) expressed as nitrogen (N).
- Total gaseous nitrogen losses
- Losses in housing and storage
- Other gaseous nitrogen losses
- Losses of other gaseous nitrogen compounds (N2, NO and N2O), expressed as nitrogen (N).
- Ammonia losses during grazing (N)
- Emissions of ammonia expressed as N during grazing.
---
Losses of other nitrogen compounds (N2, N2O and NO) are not calculated as grazing losses. These losses occur at a later stage due to nitrification and denitrification processes in the soil and are therefore considered as soil losses.
- Nitrogen in produced manure (N)
- The nitrogen in produced manure is equal to the excreted nitrogen minus the gaseous nitrogen losses that occur in animal housing and storages outside animal housing.
Gaseous nitrogen losses from housing and manure storages in his table are calculated according to the methodology of the Committee of Experts on the Manure act (CDM). The calculated losses differ from fixed values based on the manure act.
- Manure removal from farms
- Removal of manure from agricultural holdings.
Removal of manure is mainly due to a lack of sufficient land area for spreading manure. The manure spreading allowance for a farm is calculated as area of agricultural land multiplied by the amount of manure allowed per hectare.- Nitrogen (N) in removed manure
- Manure supply to farms
- Supply of manure takes place mainly on agricultural holdings with enough land available for spreading manure.
- Nitrogen (N) in supplied manure
- Manure processing
- Manures processing where end products are no longer considered as manure.
For example manure incineration or emissions of nitrogen during aerobic treatment of manure from fattening calves.- Processed nitrogen (N)
- Net manure exports
- Manure exports minus manure imports.
- Nitrogen exports (N)
- Spreading area for manure
- Spreading area for minerals is calculated as the available area of agricultural land multiplied by the permitted amount of mineral per hectare (fertilising standard) for animal manure.
- Spreading area for nitrogen (N)
- The spreading area for nitrogen is calculated by multiplying the fertilising standard for animal manure (170 kg N) per hectare by the available area of agricultural land.
The European Commission allows the Netherlands expansion of this standard up to 250 kg nitrogen per hectare. This extended standard applies to manure from grazing livestock only. Besides the agricultural area must at least consist of 70 percent grassland till 2013 and from 2014 onwards of at least 80 percent grassland. For sandy soils in certain regions the extended standard is limited from 2014 onwards to 230 kg N per hectare.
The fertilising standard for nitrogen from livestock manure was introduced in 2006.
- Use of animal manure
- Use of nitrogen and phosphate in animal manure on agricultural holdings. Use is calculated as production of manure on agricultural holdings plus supply of manure to agricultural holdings minus removal of manure from agricultural holdings. The use of manure comprises the spreading of stored manure by means of application techniques and the manure produced by livestock during grazing.
- Use of nitrogen (N) in agriculture
- Nitrogen excretion minus gaseous losses from housing and storage, plus nitrogen in supplied manure, minus nitrogen in removed manure.
