Abstract

The non-enriched FYM may contribute to a less dynamic and resilient soil ecosystem, potentially necessitating increased reliance on synthetic fertilizers and pesticides hence, in this study, FYM underwent an enrichment process using a liquid microbial consortium. Unenriched FYM had slightly lowered moisture (41.21%) due to reduced bulk density. Enrichment with microbes raised moisture (42.32%) and slightly increased electrical conductivity. Total organic carbon remained stable, but nitrogen and phosphorus increased post-enrichment. Potassium, calcium, and magnesium stayed unchanged. Enrichment notably raised sulfur, zinc, and boron levels and slightly increased copper, manganese, iron, and nickel. No cadmium or leads were found, while chromium and nickel were below Indian standards. Enriching FYM with microbes boosts nutrient availability, soil health, and crop yields. It enhances organic matter decomposition, fostering a diverse microbial community for improved soil structure and nutrient cycling. This practice increases soil carbon, aiding water retention capacity. In essence, enriching FYM with microbial consortia is a cost-effective; eco-friendly means to enhance soil fertility, crop productivity, and long-term agricultural sustainability.

Conclusion

Enriching farmyard manure (FYM) with a liquid microbial consortium is a proven, sustainable agricultural practice. The process significantly improves soil properties, including increased moisture content, electrical conductivity, and enriched essential nutrients like nitrogen and phosphorus. This cost-effective strategy not only enhances nutrient availability but also promotes a diverse microbial community, contributing to improved soil structure, enhanced water retention, and increased crop yields ultimately supporting long-term agricultural sustainability.
