Microbial interactions facilitated by humic acid in citrus tree rhizosphere: Implications for growth and yield
Author(s): Isabella Schmidt, Ahmed Zayed and Lucia Bianchi
Abstract: Microbial interactions in the rhizosphere of citrus trees play a significant role in plant growth, nutrient acquisition, and disease suppression. Humic acid (HA), a complex mixture of organic molecules formed during the decomposition of plant and animal matter, has been found to enhance microbial activity in the rhizosphere. This article explores the role of HA in facilitating beneficial microbial interactions within the rhizosphere of citrus trees and its implications for growth and yield. Studies have shown that HA promotes the growth of both beneficial bacteria and fungi, enhancing nutrient uptake and improving plant resistance to pathogens. Moreover, HA can modify the soil environment, creating conditions that favor the establishment and proliferation of plant-growth-promoting rhizobacteria (PGPR). These interactions are crucial in the context of sustainable agricultural practices, where minimizing chemical inputs is essential. The review synthesizes existing research on HA's impact on microbial communities in citrus tree rhizospheres, examining how HA influences microbial diversity, activity, and interactions. Additionally, the article discusses the practical implications of incorporating HA into citrus cultivation practices, including potential challenges and future research directions. Findings indicate that HA can be a key tool in improving citrus tree productivity by enhancing soil health, promoting beneficial microbial communities, and increasing overall plant vigor. The objective of this article is to provide a comprehensive understanding of how HA can be utilized to foster microbial interactions that benefit citrus trees, leading to improved growth and yield outcomes. The review concludes by proposing future research avenues that focus on optimizing HA applications in citrus farming to maximize its potential benefits.
