2. Statistical presentation Top
2.1. Data description

Annual crop statistics provide statistics on main areas, vegetables and permanent crops, as well as production levels and yields. Statistics are collected from many different sources: surveys, administrative sources, experts and other data providers. The dataset includes early estimates (before harvest) and final data. Data are mainly collected at national and regional level (NUTS1/2).

2.2. Classification system

Hierarchical crop classification system

2.3. Coverage - sector

Cultivation of non-perennial plants, perennial plants and plant propagation (NACE A01.1-01.3)

2.4. Statistical concepts and definitions

See: Manual of annual crop statistics

2.5. Statistical unit

Utilised agricultural area cultivated by the holding.

2.6. Statistical population

All farms growing crops.

2.7. Reference area

The entire territory of the country.

2.8. Coverage - Time

3.3. Data collection

Definitions Question In case yes, how do they differ?
Do national definitions differ from the definitions in Article 2 of Regulation (EC) No 543/2009? YES

Poland uses the concept “sown area” (and only in case of huge damages or disasters it could be recalculated). Usually Poland doesn't survey the area after the harvest and the yields are calculated on the basis of the sown area and not the harvested area.

Are there differences between the national methodology and the methodology described in the Handbook concerning e.g. the item and aggregate calculations? NO
Are special estimation/calculation methods used for main crops from arable land? NO
Are special estimation/calculation methods used for vegetables or strawberries? NO
Are special estimation/calculation methods used for permanent crops for human consumption? NO
Are special estimation/calculation methods used for main land use? NO
Do national crop item definitions differ from the definitions in the Handbook  (D-flagged data)? NO  
In case yes, how do they differ? ( list all items and explanations)
In case data are delivered for one of the items below, describe the crop species included in the item:


Population

Which measures were taken in order to make sure that the requirement stipulated in Art. 3.2 are met?
(Statistics shall be representative of at least 95 % of the areas of each table in the Regulation).

The total cultivated area( satellite data, administrative data)

Is the data collection based on holdings? NO
If yes, how the holdings were identified? Other
If not, on which unit the data collection is based on?

Mostly on parishes (i.e. the smallest administrative units)

When was last update of the holding register? (month/year)

March/2022

If there were considerable differences, which factors explain them?

In FFS  fruit trees and bushes from plantations were surveyed separately

 

Between orchard survey and ACS there were some differences in methodology and terms, in orchard survey the population was dedicated to holdings with special fruit production (e.g. apple, peach and apricot production in orchard)
