The Farm Structure Survey collects data on the structure of agricultural and forestry holdings, including manure management (storage, use and application techniques of manure).
According to EU legislation, a census is conducted every ten years, with sample surveys at three- or four-year intervals in between. The module on manure management is not included in every survey but in the 2016 sample survey, the 2020 census, and 2026 sample survey. All agricultural and forestry holdings meeting the legislation's minimum requirements must participate. Relevant available administrative data sources are used and complemented with questionnaires.
For the census, regional data are available – partially at the municipality level. In applicable sample survey years, the smallest geographical unit available is that of the federal province.
