Soil fertility improvement by addition of bio-fertilizer Azolla pinnata R Br and its utilisation in a eco-friendly way

Author(s): Bhagyeswari Behera, Atia Arzoo
Abstract: The alarming rate of contaminations of fertilizers in soil has become an important issue worldwide due of their undesirable effects on environment, human health and serious threat to food safety. Excessive addition of synthetic fertilizer leads to chemical pollution in soil. Chemical pollutants can easily enter the food chain if contaminated soils are used for the production of food crops. So, reducing the effects of heavy metal on food crop, an attempts were taken to use of Azolla pinnata R. Br. as a bio-fertilizer. The novelty of this work is the replacement of synthetic fertiliser by utilization of Azolla pinnata R. Br. as biofertiliser in an environment friendly way. This research address the research gap by analyzing the elemental content present in Azolla pinnata R. Br. In the present study it was found that the Azolla pinnata R. Br. contains different useful elements which are major and minor element for plant nutrient. In the present study, dry Azolla pinnata R. Br. powder was added to the garden soil and elemental contents of both initial and final soil were measured and effect of these nutrients on growth of Vigna radiate L. were analyzed. It was observed that the soil treated with Azolla pinnata R. Br. biomass contained more nutrient than the normal garden soil. This biomass treated soil was also utilized for growing Vigna radiate L. seedling. It was also found that the Vigna radiate L. seedlings was grown better in biomass treated soil than the normal garden soil. So Azolla pinnata R.Br. can be recommended as the organic fertilizer which can fulfil the nutrient level of soil and enhance the soil fertility.
