Despite the persistent use of synthetic pesticides in agriculture, there is a growing interest in exploring environmentally friendly alternatives. Plant-derived essential oils, known as natural biocides, have emerged as a potential solution. However, their application may carry unintended consequences, particularly for non-target organisms. In light of these considerations, this study is dedicated to advancing the frontier of research in environmental bioindicators by investigating the effects of various essential oils on microorganism diversity within agricultural soils. Our research begins with a comprehensive analysis of the microorganisms inhabiting diverse agricultural soil types. These microorganisms are categorized into two groups: beneficial and harmful. Subsequently, we assess the toxicity thresholds of essential oils on both categories of microorganisms. Our ultimate objective is to strike a balance between reducing harmful microorganisms while preserving the vital contributions of beneficial ones. This study aims to identify the ideal dosages of natural biocides necessary to maintain this delicate balance. As our research progresses, we hope to make a significant contribution to the understanding of the potential of natural biocides as sustainable alternatives in agriculture, and thus actively shape the ever-changing landscape of environmental bioindicators.
