Abstract

Biofertilizers are natural materials include living microorganisms that improve the soil nutrient content and encourage plant development. Mycorrhizal fungi, phosphate-solubilizing bacteria, and nitrogen-fixing bacteria such as Azotobacter and Rhizobium are common forms of biofertilizers. Soil contains free-living nitrogen-fixing bacteria belonging to the genus Azotobacter. Because they transform atmospheric nitrogen (N2) into ammonia, which plants can use as a fertilizer, these bacteria essential to the nitrogen cycle. Because of its capacity to flourish in aerobic environments, Azotobacter is frequently found in agricultural soils, where it enhances soil fertility. This abstract aims to comparatively study the efficiency of different species of Azotobacter as a biofertilizer.
