A Study on Microbial Fingerprinting of Different Organic Samples in Vermicompost
Journal Title: PARIPEX-Indian Journal of Research - Year 2016, Vol 5, Issue 10
Abstract
Environmental degradation is a major threat confronting the world, and the rampant use of chemical fertilizers contributes largely to the deterioration of the environment through depletion of fossil fuels, generation of carbon dioxide and contamination of water resources. It leads to loss of soil fertility due to imbalanced use of fertilizers that has adversely impacted agricultural productivity and causes soil degradation. Now there is a growing realization that the adoption of ecological and sustainable farming practices can only reverse the declining trend in the global productivity and environment protection. In nature’s laboratory there are a number of organisms that have the ability to convert organic waste into valuable resources containing plant nutrients and organic matter, which are critical for maintaining soil productivity. Microorganisms and earthworms are important biological organisms helping nature to maintain nutrient flows from one system to another and also minimize environmental degradation. This clearly indicates that earthworm population decreases with soil degradation and thus can be used as a sensitive indicator of soil degradation. The present study intended to isolate and identify the bacteria present in four different samples such as cowdung, cowdung compost, slurry, slurry compost. The physiochemical parameters of all the samples and the surface morphology of them were also analysed.
