The Comparative Energy Efficiency of Organic Farming

Summary in the original language of the document

Organic farming is generally a more energy efficient system of food production. Comparative analyses of fifteen crop and livestock sectors indicate that UK organic farming uses around 26% less energy per tonne of output on average. The main energy saving is from the non-use of industrially produced inorganic nitrogen fertiliser. Organic farming is more energy efficient for wheat, most field vegetables, milk, red meat and pigs, but it is less efficient for poultry production.
