Abstract

Fungi are essential eukaryotic microorganisms that contribute to decomposition, organic matter recycling, nutrient cycling, and ecosystem balance. They adapt to various stress, environmental niches, survive pH and temperature ranges, and in consortia play crucial roles in biological cycles like mineral and water absorption, chemical transition, stomatal activity, and substance biosynthesis. Fungi with their own unique physiology, help plants cope with adaptive challenges like drought, salinity, humidity, etc. Implantation of fungi as a soil quality booster is essential, as they produce extracellular enzymes essential for nutrient cycling in natural and disturbed ecosystems. The study highlights the role of plant growth promoting wild fungi can impart in enhancing the soil fertility by producing various extracellular enzymes, phytohormones, and organic acids, which supports plant growth and enhance resistance to various abiotic stresses. And their variable, adoptive behaviour in natural, wild environment.

Conclusion

Soil fungi contribute to improved soil fertility by producing organic acids, extracellular enzymes, and phytohormones. Understanding these processes can inform sustainable agricultural practices aimed at optimizing soil health and plant performance. Understanding the physiological roles of fungal species in soil colonization is of paramount need. This involves examining their growth patterns, reproductive strategies, and responses to environmental cues. By deciphering the physiological characteristics of these fungi, we can elucidate their adaptive strategies for thriving in diverse soil conditions and niches. Ultimately, the extended outcomes of this research will provide detailed insights into the prevalence and ecological significance of widely adopted fungal species in soil ecosystems of different kinds (fertile and barren). By elucidating their roles in bioconversion, nutrient bioavailability, and recycling processes, we can discern their impact on soil fertility dynamics. This knowledge will not only enhance our understanding of soil microbial ecology but also inform sustainable soil management practices aimed at optimizing agricultural productivity and ecosystem’s health.
