3.1. Data description

This table contains data on mineral fertiliser consumption reported by countries or estimated by Eurostat. The mineral fertilisers are reported in tonnes of nitrogen (N) and phosphorus (P). Another name for mineral fertilisers is inorganic fertilisers, meaning that they are manufactured. Fertilisers are also referred to as agricultural nutrients. For a definition see 3.4.

Nutrients from fertilisers are absorbed by plants from the soil and sustain growth. With the harvest of crops for human and livestock consumption and industrial uses, N and P is removed from the soil. Continuing agricultural production without fertilisation could lead to soil degradation and erosion. Fertilisers are therefore essential to sustain agricultural production. Fertilisers are also used to improve crop yields and soils.

The use of manufactured fertilizers as a regular farming practice began in most European countries in the mid to late nineteenth century but the greatest increase in consumption in these countries occurred in the three decades following World War II. The manufacturing of fertilisers greatly enhanced crop yields and agricultural production, and aided the large increase in the world population in the 20th Century.

Excessive use of fertilisers can lead to water, soil and air pollution. The agricultural and environmental context of fertiliser use is described in the Agri-environmental indicator factsheet (see 10.2).

 

3.2. Classification system

Not applicable.

3.3. Coverage - sector

Agriculture.

3.4. Statistical concepts and definitions

Inorganic fertilizer’ means a fertilizer in which the declared nutrients are in the form of minerals obtained by extraction or by physical and/or chemical industrial processes. Calcium cyanamide, urea and its condensation and association products, and fertilizers containing chelated or complex micro-nutrients may, by convention, be classed as inorganic fertilizers (Regulation (EC) No 2003/2003).

In the context of this table inorganic fertilisers refer to inorganic fertilisers applied to agricultural land.

3.5. Statistical unit

Countries have reported data on the use of inorganic fertilisers in agriculture at NUTS 0 level. Some countries have also reported data at NUTS 2 level.

3.6. Statistical population

The data on inorganic fertiliser use in agriculture are reported by countries at NUTS 0. In some cases data have also been provided at NUTS 2 level.

In principle only the consumption of inorganic fertilisers in agriculture should be covered. Countries have used different methodologies and data sources to estimate the use of inorganic fertilisers in agriculture. It is often difficult to distinguish between agricultural and non-agricultural use, the data reported by countries therefore may include non-agricultural use.

3.7. Reference area

EU Member States, Norway and Switzerland, Albania and Turkey, and their regions down to NUTS 2 level where appropriate.

3.8. Coverage - Time

2000-2017.

3.9. Base period

Not applicable.


4. Unit of measure Top

Variables are measured in tonnes of N and tonnes of P.


5. Reference Period Top

The reference period is the calendar year. Data collection is however not harmonised at EU level. Countries collect data for different reference periods. Countries may therefore report data collected for crop years (t-1/t) in calendar year t without any corrections.


6. Institutional Mandate Top
6.1. Institutional Mandate - legal acts and other agreements

Eurostat has no legal act in place requiring these data. Data have been collected from the countries by "gentleman's" agreement.

6.2. Institutional Mandate - data sharing

Not applicable.


7. Confidentiality Top
7.1. Confidentiality - policy

Regulation (EC) No 223/2009 on European statistics (recital 24 and Article 20(4)) of 11 March 2009 (OJ L 87, p. 164), stipulates the need to establish common principles and guidelines ensuring the confidentiality of data used for the production of European statistics and the access to those confidential data with due account for technical developments and the requirements of users in a democratic society.

7.2. Confidentiality - data treatment

Not applicable.


8. Release policy Top
8.1. Release calendar

Not applicable.

8.2. Release calendar access

Not applicable.

8.3. Release policy - user access

In line with the Community legal framework and the European Statistics Code of Practice Eurostat disseminates European statistics on Eurostat's website (see item 10 - 'Accessibility and clarity') respecting professional independence and in an objective, professional and transparent manner in which all users are treated equitably. The detailed arrangements are governed by the Eurostat protocol on impartial access to Eurostat data for users.


9. Frequency of dissemination Top

Final data for year t-1 are delivered annually to Eurostat by the 30th November.


10. Accessibility and clarity Top
10.1. Dissemination format - News release

News items are released on-line on Eurostat's webpage.

10.2. Dissemination format - Publications

Data are published and explained in the Agri-environmental indicator factsheet number 5 - Mineral fertiliser consumption, available here: https://ec.europa.eu/eurostat/web/agriculture/agri-environmental-indicators .

10.3. Dissemination format - online database

Data is available in the table Consumption of inorganic fertilizers (aei_fm_usefert) on Eurostats dissemination database.

10.4. Dissemination format - microdata access

Not applicable.

10.5. Dissemination format - other

The data is used in indicator factsheets for different EU policies.

10.6. Documentation on methodology

Methodology and data transmission are discussed with countries in Eurostat Working Groups.

10.7. Quality management - documentation

Data quality and validation are discussed with countries in Eurostat Working Groups.


11. Quality management Top
11.1. Quality assurance

Data quality and validation are discussed with countries in Eurostat Working Groups.

11.2. Quality management - assessment

Data on fertiliser consumption is available in many countries from country specific data sources (surveys, trade/production statistics). Due to different data sources used (farmer surveys vs trade/production statistics) and inherent problems of data sources used (for instance inclusion of non-agricultural use in statistics based on trade and production) the quality of data cannot be sufficiently verified. There is need for a common methodology to estimate Fertiliser consumption by agriculture to ensure reliable and consistent estimations and comparability across Member States.

Eurostat promoted in 2012 the establishment of national discussion groups for fertiliser statistics. The objectives of these groups were:

  • Discuss the quality of existing data sources.
  • Propose and implement improvements in quality or data availability.
  • Propose and implement a strategy to estimate data as required by Eurostat.
  • Establish official statistics.
  • Ensure coherence and consistency of statistics reported to the European Commission and other international obligations.

Many countries have established such discussion groups. Results are shared at Eurostat Working Group meetings. 


12. Relevance Top
12.1. Relevance - User Needs

Main users are the general public and policy-makers interested in the integration of environmental concerns into the Common Agricultural Policy (see COM (2006) 508 final).

12.2. Relevance - User Satisfaction

Not applicable.

12.3. Completeness

Data have been received from most countries. Where data was not transmitted by countries for the requested period, data from National Inventory Submissions to UNFCCC, Fertilizers Europe, FAOSTAT, or national publications have been used to complete the missing data. Sales data from Fertilizers Europe are also published in table aei_fm_manfert in the online database of Eurostat. 


13. Accuracy Top
13.1. Accuracy - overall

Most countries use data based on sales and/or production and trade statistics. Some countries use farm surveys. Data based on sales and/or production and trade statistics may be biased due to the inclusion of fertilizers not used in agriculture (private/public sector use, explosives, intermediate products etc). Reliability and accuracy of farmer surveys depend a.o. on the sampling design and size.

13.2. Sampling error

Not applicable.

13.3. Non-sampling error

Not applicable.


14. Timeliness and punctuality Top
14.1. Timeliness

Data are requested by gentlemen's agreement. Data received are validated and uploaded in Eurostat database.

14.2. Punctuality

Not applicable.


15. Coherence and comparability Top
15.1. Comparability - geographical

Geographical comparability is limited due to different methodologies and data sources applied.

15.2. Comparability - over time

In general good comparability within countries over time.

15.3. Coherence - cross domain

Differences are expected with table aei_fm_manfert, due to different methodlogy and data sources used.

15.4. Coherence - internal

The coherence is acceptable. If a sum of the fertiliser consumption in a country's NUTS2 regions is not exactly corresponding to the same country's NUTS0 fertiliser consumption; it is most likely due to rounding.


16. Cost and Burden Top

Data are mainly derived from existing data sources and reporting requirements.


17. Data revision Top
17.1. Data revision - policy

Revisions are made if and when countries revise the data or new data come available. It happens each year that one or mode countries revise one or more years in the time series. This can be due to better estimations or models becoming available.

17.2. Data revision - practice

When data is revised it is flagged with an r for a period of time. The r is removed in the subsequent update of the annual data.


18. Statistical processing Top
18.1. Source data

Source data are collected in tonnes of nirtogen and phosphorus from countries or national/international organisations.

18.2. Frequency of data collection

Data for year t-1 are delivered annually to Eurostat by the 30th November.

18.3. Data collection

Data are received using a pre-described format from the countries based on gentlemen's agreement and transmitted via Edamis.

18.4. Data validation

Data validation includes checks with data from available data sources in Eurostat, National Inventory Submissions to UNFCCC, Fertilizers Europe, etc.

18.5. Data compilation
