Azotolin is an eco-friendly microbial fertilizer that contains the bacteria Azotobacter croococcum which is known to fix considerable quantity of nitrogen in the range of 20-40 kgs of nitrogen per hectare in the rhizosphere region of the soil, for non-leguminous crops. The bacterium includes hormones that help plants in better germination, early emergence and better root development. It helps in synthesis of growth regulating substances like auxins, cytokinin and Giberellic Acid (GA). It also protects the plants from phyto-pathogens, improves nutrient uptake. Azotolin helps in reduction of inorganic nitrate in take by 25% and helps in enhancing the crop yield by up to 15%.
