The economic activities in the agricultural sector are broken down conceptually into ‘production activities’ (e.g. cropping a hectare of wheat or fattening a pig). These activities are characterised by physical output and input coefficients. For most activities, total production quantities can be found in statistics and output coefficients derived by division of activity levels (e.g. ‘soft wheat’ would produce ‘soft wheat’ and ‘straw’, | The economic activities in the agricultural sector are broken down conceptually into ‘production activities’ (e.g. cropping a hectare of wheat or fattening a pig).

The farm balance positions are seed use (SEDF) and losses (LOSF) on farm (only reported for cereals) and internal use on farm (INTF, only reported for manure and young animals).
