Energetic analysis of four farming systems during the conversion from conventional to organic farming system in the Sacramento Valley-California



Energetic analysis of four farming systems during the conversion from conventional to organic farming system in the Sacramento Valley-California



Rivista di Agronomia 29(3, Supplement): 493-498



In field trials in 1989-93, a comparison was made of the energy inputs (mechanical cultivation, labour and seeds, fertilizers and pesticides) required for the production of maize, tomatoes, wheat, beans safflower and oats/vetch in rotation in organic, low-input, conventional and high input systems. The organic system was 60% more energy efficient than the conventional system and 50% and 40% more efficient than the high and low input systems respectively.
