Effects of Intact Soil Bacterial Community on Plant Growth and Soil Physicochemical Properties: Effects of Intact Soil Bacterial Community

Abstract

Soil microorganisms play an important role in the nutrient transformation and circulation of terrestrial ecosystem. Some studies found that intact soil microbial community could purify the soil environment and promote plant growth. However, the effects of intact soil microbial community and their affect mechanisms were not clearly known. In order to further understand the effects of intact soil bacterial community, we aim to monitor changes of soil physical and chemical properties and the growth of plants in soils with intact and damaged soil bacterial communities, respectively. The results showed that the intact soil bacterial community significantly affected the growth of roots, and had a significant impact on soil nutrients and enzyme activities.
