Review of Humic Substances Developed in Organic Waste Aerobic Composting and Its Agronomic Effect.
摘要
Abstract
As important final product of organic waste aerobic composting, humic substance (HS) is considered as a cru-cial index to assess composting process and its product maturity. HS contains various of functional groups, which bring sig-nificant agronomic benefits to crop and soil, such as nutrient reservoir, soil physical and chemical properties improvement. The research progress in recent years was summarized, including structure, formation way as well as regulation of HS de-velopment during aerobic composting. The effect of main physical-chemical parameters of aerobic composting, including raw materials type, bulking agent type, temperature, moisture content, C／N ratio, oxygen content, pH, porosity, on the formation and quality of HS was reviewed and discussed. The relationship between HS functional groups and its agronomic effects was also elaborated, including plant growth enhancement, water holding capacity improvement, disease suppression and nutrient preserving reinforce. Finally, the direction of further research was looked forward on the basis of current a-chievement. Probe into aggregate structure and chemical information of HS using synchrotron radiation X-ray microtomogra-phy and soft X-ray spectromicroscopy technology were proposed to facilitate deep analysis. On summary, the aim of this re-view is to provide the insight to understand the relationship between HS characteristic and beneficial functions to corre-sponding agronomic improvement to soil and crop.关键词
