2.1. Data description

Annual crop statistics provide statistics on the area under main arable crops, vegetables and permanent crops and production and yield levels.  The statistics are collected from  a wide variety of sources: surveys, administrative sources, experts and other data providers. The data collection covers early estimates (before the harvest) and the final data. Data are collected mostly at national level but for some crops also regional data exist (NUTS1/2).

The harvest of cereals etc.

For each crop, questions are asked on arable land, total yield (hekto kilo), average yield (hekto kilo / hectare) and water percent if the production does not appear in dried weight. Water percentage is used to calculate standard moisture content (15 per cent for cereals and peas and 9 per cent for rape). Harvest of grain maize and corn cob mix is included in the statistics from 2011. Statistics on straw show the production and use of straw by the above-mentioned crops. Output is measured as a relation between yield (grain, rape and peas) and expected straw yield, while the use of straw is based on questionnaire information on the distribution of straw areas used for firing, for fodder, for other purposes. From 2006 the results are compiled for the new administrative structure in Denmark (regions). Regions are divided on specific agricultural land (sub-divisions of regions).

Harvest of roughage

Includes harvest of sugar beet, potatoes and roughage plus grain and corn harvested for silage or green fodder. Data collection: yield estimates from experts. 

Forecast of areas planted with winter crops for harvest the following year.

Crops include: winter wheat, winter barley, rye, triticale and winter rape. The forecast is from 2016 prepared by DAKOFO and the Association of Danish plant breeders. DAKOFO is a trade association for grain and feed trade in Denmark.

2.2. Classification system

Hierarchical crop classification following the EU classifications in Eurostat Handbook for Annual Crop Statistics.

2.3. Coverage - sector

The agricultural sector. Growing of non-perennial crops, perennial crops and plant propagation (NACE A01.1-01.3)

2.4. Statistical concepts and definitions

See: Annual crop statistics Handbook

2.5. Statistical unit

Utilised agricultural area cultivated by an agricultural holding.

2.6. Statistical population

All agricultural holdings growing crops.

2.7. Reference area

The entire territory of the country.

2.8. Coverage - Time

The statistics in their present form are generably available from 1990. However, see 'Comparability over time' for specification.

2.9. Base period

The statistics cover harvest in the calendar year.


3. Statistical processing Top

Data for the harvest of grains, rape etc. is collected annually from farmers using questionnaires and every 3rd year for vegetables etc. The collected data is corrected based on consistency rules and yield limits. Corrected data are raised to the total population. Harvesting of roughage, Forecast for winter seed and Seed for seedling are collected annually from experts via questionnaires. The collected yields are raised by total areas (application for support).

Additional comments

The crop statistics are compiled using three different approaches:

  1. Results on cereals, dried pulses and rape are based on a sample survey, where about 2800 farmers are selected (ca. 8 per cent of all farmers with such crops).  
  2. Results on root crops and green fodder plants are based on expert estimates. The experts are the local experts belonging to the Farmers Advisory System.
  3. Results on vegetables and fruits, where census surveys with thresholds are conducted periodically for the single sectors (vegetables and strawberries in the open, vegetables in greenhouses, berries and stonefruit). Results for apples and pears are collected when surveys on permanent crops are conducted. In years without surveys, expert estimates are used.
  • All three approaches result in data on areas, yields and production. The areas used for estimating total production is From FSS and the IACS-support system for support to farmers.
  • The early estimates on main crops are based on previous years results, early figures from the IACS and information based on agricultural magazines etc.
  • Regarding the areas on winter crops, estimates are made based on the amount of certified seeds for cereals and rape.
  • Regarding land use statistics, information from crop production statistics, FSS, Forest surveys etc. are combined.

7. Timeliness and punctuality Top

The statistics are usually published without delay to the scheduled date. Preliminary data for the harvest of cereals, rape and pulses are published in late November. Final statement, including results for provinces and regions are published March of the following year, where the coarse fodder harvest also is published. End of reference Period: end of November. The forecast for the following year's winter land released in early December. End of reference Period: October 15.

8. Coherence and comparability Top
8.1. Comparability - geographical

Similar statistics are produced among EU members and are available from the Eurostat's website. The statistics comply with EU standards.

8.1.1. Asymmetry for mirror flow statistics - coefficient

Not applicable.

8.2. Comparability - over time

Length of comparable time series

The final figures on crop yields of grain are, in principle, comparable as far back as 1900. Changes in methodology must be taken into account, but the present compilation method has been used since 1971. The results on crop yields at regional level are only comparable as from 2006 due to a new administrative structure of regions in Denmark. For 2006, results are compiled on the basis of the former counties as well as the present regions. Figures on coarse fodder are fully comparable as from 1982 and onwards.

8.3. Coherence - cross domain

  Data source
With which other data sources the crop statistics data have been compared?  Farm structure survey 2016
IACS
If others, which?
If no comparisons have been made, why not?

Mainly check of definitions, units and areas. The same source - National IACS-register - is used a base for the various populations. No comparison of statistic results across domains, though, as crop data only are collected from one source.

The forecast for areas with winter seeds can be compared with the later results according to the FS Survey


Results of comparisons FSS 2016 (if available) Vineyard survey 2015 IACS Other source(s)  In case of other sources, which?
