Azotobacter as a Possible Bio-fertilizer for Managing Soil and Plant Health: A Review

Abstract

Azotobacter is one kind of bio-fertilizer that is sprayed onto the soil's surface or distributed through seeds. It is a living organism that helps colonise the rhizosphere, or the internal portions of plants, and it also promotes development by making more primary nutrients available to plants. A free-living, gram-negative bacterium with an oval or spherical form is called an Azotobacter. It is a significant bio-fertilizer that increases soil fertility by fixing nitrogen, which in turn increases crop productivity by allowing plants to absorb biologically active chemicals through the process of biosynthesis. In comparison to chemical fertilisers, it is more environmentally benign because it contributes significantly to nutrient cycle and boosts nutrient availability. According to study, using Azotobacter also boosts some crops Azotobacter yields. An increasing body of research has shown that using bio-fertilizer, either on its own or in conjunction with other fertilisers or pesticides, can produce positive outcomes when it comes to saving natural resources. Thus, it is preferable to utilise bio-fertilizers in order to slow down the rate at which chemicals are being used up on the soil. It is therefore crucial to become more knowledgeable about the significance and applications of the specific bio-fertilizer before putting it to use.
