Effects of fertilizer application on the bacterial community and weathering characteristics of typical purple parent rocks.

ABSTRACT:

Introduction

Rock weathering is a fundamental process that shapes Earth's topography, soil formation, and other surface processes. However, the mechanisms underlying the influence of fertilizer application on weathering remain poorly understood, especially with respect to bacterial intervention.

Methods

In this study, purple parent rocks from Shaximiao Group (J₂s) and Penglaizhen Group (J₃p) were selected to investigate the effects of fertilizer application on the bacterial community and weathering characteristics of these rock by leaching experiment.

Results

The results revealed that: fertilizer application, especially when at high levels, greatly altered the abundance, diversity and composition of the bacterial community in weathered products.
