A comparation of energy flow and economic flow between organic and inorganic vegetable production systems

Energy flow,economic flow and their influence on soil environment in organic and inorganic vegetable production systems are analyzed.The results show that the vegetable's growth,yield and economic benefit in organic system are all better than those in inorganic system,the energy output/input ratio of organic system was significantly impacted by the varieties of applied organic fertilizer.The soil microbiomass in organic system are higher than that in inorganic system.
