Purpose: The aim of the study was to assess the relationship between soil pH and microbial community composition in agricultural soils.
Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries.
Findings: The study revealed significant correlations between these two factors. Studies indicate that soil pH plays a crucial role in shaping the structure and diversity of microbial communities inhabiting agricultural soils. Generally, acidic soils tend to harbor distinct microbial populations compared to neutral or alkaline soils. Acidic conditions often favor acidophilic microorganisms, such as Acid bacteria and certain fungi, while alkaline soils may support a different set of microbial taxa. Changes in soil pH have been shown to influence microbial diversity, community structure, and the abundance of specific microbial groups involved in nutrient cycling and soil health. Understanding the intricate connections between soil pH and microbial communities is vital for optimizing agricultural practices, enhancing soil fertility, and promoting sustainable land management strategies.
Implications to Theory, Practice and Policy: Neutral theory of biodiversity, phylogenetic niche conservatism and resource competition theory may be used to anchor future studies on assessing the relationship between soil pH and microbial community composition in agricultural soils. Develop region-specific soil pH management strategies tailored to different soil types, climatic conditions, and land management practices. Incorporate soil pH monitoring and management guidelines into agricultural policies and extension programs to promote soil health and sustainability.
