Abstract

Abstract:

The application of biochar changes the physical chemicals properties of soil and stimulates the activity of soil microorganisms, thus affecting soil quality and plant growth. By studying the effects of biochar on soil microorganisms, we can better understand the importance of interaction between biochar, soil and plants. However, biochar has more research on soil properties, but less on soil microorganisms. In this review, the main aspects are related to: (1) the effects of the biochar application on soil physicochemical properties; (2) the effects of biochar application on soil microbial growth; (3) the effects of biochar application on soil microbial community diversity; and (4) the effects of biochar application on soil microbial enzyme activity, microbial activity and ecological functions. The whole paper mainly describes the research progress of biochar on soil microorganisms, and predicts its application prospects, which could lay the foundation for the construction and development of farmland ecosystems in China.

Key words: physicochemical property, biochar, soil microorganisms, community, enzymatic activity
