The standard output of an agricultural product (crop or livestock), abbreviated as SO, is the average monetary value of the agricultural output at farm-gate price, in euro per hectare or per head of livestock. There is a regional SO coefficient for each product, as an average value over a reference period (5 years, except for the SO 2004 coefficient calculated using the average of 3 years). The sum of all the SO per hectare of crop and per head of livestock in a farm is a measure of its overall economic size, expressed in euro.
The SO 2004 was calculated using the average of 2003, 2004 and 2005 prices. It is applied in 2007 Farm structure survey data and has been applied to 2005 Farm structure survey to allow comparability over the time periods.
The SO 2007 was calculated using the average of 2005, 2006, 2007, 2008 and 2009 prices. It is applied in the 2010 Farm structure survey data.
The SO 2010 is being calculated using the average of 2008, 2009, 2010, 2011 and 2012 prices. It is being applied in the 2013 Farm structure survey data.
