In the frame of the Farm Structure Survey, data are collected on the structure of the agricultural and forestry holdings, including manure management (manure storage, use and application techniques).
According to EU-legislation, a census is conducted every ten years, with sample surveys in three-year or four-year intervals in between. However, the information on soil management is not included in every survey (it is included in the 2016, 2020 and 2026). All agricultural and forestry holdings which meet the minimum requirements set out in the legislation are required to take part. 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.
