Abstract

Abstract: The energy utilization in major crop systems in three selected counties in Northeastern plain of China was investigated.Some suggestions about effective utilization of energy especially from industrial or fossil fuel were given.Those crops are rice,corn,sorghum,wheat,soybean,millet,potatoes,sugar beets and sunflowers.

Key words: stable isotope, ecosystem, pre-existing organic carbon, development stage, FACE
