Soil Microbiome Modulation Mediated by Fermented Organic Preparations

Abstract

The soil microbiome is a dynamic and intricate ecosystem that plays a fundamental role in maintaining soil health, facilitating nutrient cycling, and supporting plant growth. However, the excessive and prolonged application of chemical fertilizers and pesticides has severely disrupted microbial diversity, leading to soil degradation, reduced fertility, and environmental contamination. In response to these challenges, fermented organic preparations (FOPs) have re-emerged as promising bio-enhancers capable of restoring microbial equilibrium in agricultural soils. This review investigates the role of various FOPs, including panchagavya, jeevamrutham, beejamrutham, and fish amino acid, in modulating the soil microbiome and promoting sustainable agricultural practices. FOPs facilitate solubilization of essential nutrients, enhance organic matter decomposition, and suppress soil-borne pathogens through competitive exclusion and antibiotic production. Additionally, the integration of such preparations with traditional and modern farming techniques fosters a holistic approach to regenerative agriculture, reducing dependence on synthetic inputs while ensuring long-term soil sustainability. The review also explores the challenges associated with FOP application, such as variations in microbial composition due to environmental factors, inconsistencies in fermentation processes, and the need for scientific validation of traditional formulations. Advances in microbial biotechnology, metagenomics, and precision agriculture can help optimize the efficacy of these preparations, making them more reliable for large-scale agricultural adoption. By emphasizing the role of indigenous knowledge and modern scientific advancements, the review underscores the necessity of adopting microbial-based soil management strategies for improved soil health, climate resilience, and sustainable food production.
