Crop rotation and native microbiome inoculation restore soil capacity to suppress a root disease

Y. Zhou, Z. Yang, et al.

This groundbreaking study explores the role of crop management strategies in combating peanut root rot disease. Monocropping struggles against more effective microbial assemblies seen in crop rotation. Remarkably, restoring key soil microbes significantly enhances disease resistance. Discover the insights from this research conducted by Yanyan Zhou, Zhen Yang, Jinguang Liu, Xudong Li, Xingxiang Wang, Chuanchao Dai, Taolin Zhang, Víctor J. Carrión, Zhong Wei, Fuliang Cao, Manuel Delgado-Baquerizo, and Xiaogang Li.

Abstract
This study investigated the impact of crop management (monocropping vs. rotation) on soil capacity to suppress peanut root rot disease. Monocropping led to less effective microbial assemblies in disease suppression compared to crop rotation. Depletion of key rhizosphere taxa in monocropping, due to competition for limited exudates, reduced disease resistance. Supplementation with depleted strains restored disease suppression, highlighting the role of native soil microbes and the potential of microbial inocula for disease control.
