Abstract

Soil degradation is a pressing environmental issue exacerbated by factors such as rapid population growth, intensified economic activities, and climate change. Among the many contributors to this degradation, the accumulation of poultry waste, particularly chicken feathers, poses a significant challenge. Globally, approximately 24 billion chickens are slaughtered annually, resulting in the generation of around 8.5 billion tonnes of poultry feathers, with India alone contributing an estimated 350 million tonnes. These feathers, composed primarily of keratin, are highly resistant to natural degradation, leading to their accumulation in the environment.


Microorganisms play a pivotal role in the natural decomposition of keratin-rich materials like feathers, contributing to nutrient recycling and soil health restoration. This study investigates the microbial communities in normal, uncontaminated soil compared to those in soil polluted with poultry feathers. By employing microbial profiling techniques, the study aims to identify the diversity, abundance, and functional roles of these microorganisms in feather degradation. The findings provide insights into the ecological impact of feather pollution on soil microbiota and underscore the potential of microbial communities in developing sustainable waste management strategies. Understanding these microbial dynamics can inform practices to mitigate soil degradation and enhance soil resilience in the face of increasing agricultural and industrial pressures
