Assessing the Role of Soil Microbiome Diversity in Enhancing Plant Resistance to Pathogens in Organic Farming Systems

Abstract

The goal of this study is to investigate the link between organic farming methods meant to defend plants against disease and soil microbial diversity. The greater numbers of beneficial microbial communities shown by organic farming clearly improve bacterial diversity. Among these groups are those of biocontrol fungus, phosphate-degrading bacteria, and nitrogen-fixing bacteria. Among the molecular defenses plants grown in organic soil displayed were increases in chlorophyll, phenolic compound production, peroxidase enzyme activity, and disease severity. This supports the hypothesis that people are less likely to become sick when surrounded by soil bacteria. Organic growing of plants provides the possibility to improve soil quality, lower dependency on synthetic pesticides, and lower incidence of plant illnesses. Furthermore much more study on the long-term changes in plant species enhancing disease resistance and their interrelationships is absolutely necessary. These findings emphasize the need of controlling soil microorganisms in building environmentally friendly farming systems.
