| Energy efficiency and greenhouse gas (methane and nitrous oxide) emissions were investigated in 2003 on 20 organic farms in the central part of Poland (Kujawsko-pomorskie voivodeship) using a questionnaire developed in the Institute of Soil Science and Plant Cultivation in Pulawy (Poland). Statistical data from the Central Statistical Office concerning the agriculture in the Kujawsko-pomorskie voivodeship was also used. A simple index (Ee) defined as a ratio of the total energy value of agricultural production (Pe) to the material and energy inputs (Ne) (in MJ) was used to evaluate the energy efficiency. The average value of this index was 2.05; however, it ranged from 0.04 to 16.59. In the organic farms, direct energy carriers (liquid and solid fuels and... |
