Energy Assessment of Organic Production

The paper presents efficiency of material and energy inputs and energy consumption of global and commodity production in organic farms with a varied production trend. These indices were expressed in traditional energy units. The results were obtained during a 3-year research conducted in 50 organic farms located in the southern Poland. The investigated facilities were divided into groups specialising in plant, animal and mixed production. Energy consumption was determined by division of the sum of energy streams i.e. direct energy carriers, raw materials and materials, investment means and repairs as well as live work by the sum of plant, animal production and other services. Efficiency of inputs was calculated as an inverse of energy consumption. The best result both with regard to energy consumption and energy efficiency were obtained by animal production farms.
