Typ rolniczy a efektywność gospodarstw ekologicznych

sources in organic farms representing selected types of farming. The object of the study was organic farms constantly participating in the Polish FADN in 2007-2009 and classified by type of farm. In 2007 the highest level of productivity and profitability of the farmland resources was realised in mixed-type farms, while in 2008-2009 - in farms focused on dairy cattle breeding. Economic efficiency and profitability of labour was at a higher level in farms oriented at animal production, but they were of larger area. Instead, capital productivity was relatively larger in farms specialized in production of field crops. The economic efficiency of capital resources was generally higher in these farms as well.
