Continuous cropping drives assembly process of soil microbial community to alter keystone taxa causing challenges.

ABSTRACT:

Background

Healthy soil is crucial for maintaining the sustainability of soil ecosystem services and ensuring food security. The soil microbiome serves as a key indicator of soil health. However, long-term continuous monoculture significantly adversely affects the diversity and functioning of soil microbial communities, posing a serious threat to sustainable agricultural development. Therefore, making it crucial to understand the microbial mechanisms underlying these challenges.

Methods

In this study, tobacco was subjected to different planting durations: 1 year (CR), 5 years (CC5), 10 years (CC10), and 15 years (CC15). The rhizosphere microbial community assembly process, composition, keystone taxa, and their relationship to continuous cropping challenges were analyzed.
