The purpose of setting up this course is to hope that everyone will learn something through the course. First, to understand the role of soil biology and biochemistry in regulating soil function, agricultural sustainability, and ecosystem services. Second, to master the ecological and biochemical processes of organisms in the soil, their impact on the environment, and the interaction between them and plants. Third, to learn how to use the current new molecular biology, microscopic and information technology to improve our understanding of the dynamic succession process of microbial communities in the soil.

  Soil Biology & Biochemistry is a forum for research on soil organisms, their biochemical activities and their influence on the soil environment and plant growth. It covers many scientific disciplines, requires the use of the basic principles of soil science, biology, chemistry and environmental science to describe and explain fundamental biological and biochemical features and processes occurring in soil systems. In addition, it focuses on quantitative, analytical and experimental aspects of such research. The purpose of setting up this course is to hope that everyone will learn something through the course: Understand the role of soil biology and biochemistry in regulating soil function, agricultural sustainability, and ecosystem services; Master the ecological and biochemical processes of organisms in the soil, their impact on the environment, and the interaction between them and plants; Learn how to use the current new molecular biology, microscopic and information technology to improve our understanding of the dynamic succession process of microbial communities in the soil. 

为积极响应国家低碳环保政策， 2021年秋季学期开始，中国大学MOOC平台将取消纸质版的认证证书，仅提供电子版的认证证书服务，证书申请方式和流程不变。
