Finnish data on manure quality is based on sampling and analysis. This method holds significant room for error and does not provide all data needed in different actions.
Thus, Luke and SYKE developed the Finnish Normative Manure System which calculated different manure types for 74 animal categories. Calculation is done for excreted faeces and urine, manure ex housing and manure ex storage.
The Finnish Normative Manure System provides data on manure quantity and quality in a documented, science-based method. The results can be used in practical farming, decision making and in developing more efficient manure use.
The documentation and first results were published in summer 2017 (Luke Reports 46-48/2017). Development of the system still continues.
