ABSTRACT
The practices of organic farming have positive effects on the environment per unit of area, but not necessarily per product unit. Organic farms have the tendency to higher soil organic matter content and minor nutrient losses such as nitrogen leaching, nitrous oxide emissions and ammonia emissions per unit of field area. An organic system had higher land use, eutrophication potential and acidification potential per product unit but has lesser energy requirements. The only effects that were found to differ considerably between the systems were soil organic matter content, nitrogen percolating, and emissions of nitrous oxide per unit of field area, land and energy use.
