Properties of organic matter in natural and reclaimed steppe soil

Abstract

Abstract: The properties of organic matter in steppe chernozem,steppe wind-blown soil and cultivated wind-blown soil were studied by analyzing the status of organo-mineral complex and the combined status and composition of humus.The results showed that different types and utilization patterns of soil had very different effects on the properties of soil organic matter.The amounts of total organic carbon,biomass C,heavy fraction C,extractable humus (HE) and loosely-combined humus and the humification degree were higher in steppe chernozem than in wind-blown soil.Steppe soil had higher amounts of total organic carbon,biomass C,heavy fraction C,HE and different combined humus than sunflower wind-blown soil,but humification degree had no obvious difference.

Key words: Soil, Humus, Organic-mineral complex, Humification degree
