The Importance of Nitrogen-Fixing Bacteria Azotobacter chroococcum in Biological Control to Root Rot Pathogens (Review)

Abstract

Abstract Intense research continues by researchers to find safe alternatives to chemical pesticides and synthetic fertilizers, and its frequent use without correct programming and guiding awareness, which has caused many environmental problems, poisoning, destruction of the ecosystem, and pollution of water, air, and agricultural soils. The use of these chemicals has also affected many living organisms, including them Humans, which motivated researchers to study and re-introduce the natural elements and beneficial microorganisms into agricultural production so that the consumer can obtain safe and healthy food free from the accumulation of harmful chemical residues. Inside the soil, which can carry out the process of converting nitrogen while it is in the state of being a gas to a state of solubility. Through this process, plants can obtain the benefit from it through the stabilization process that occurs. These bacteria perform a major work, as they work to fix nitrogen in the air This is because the plant finds it difficult to use it in its form as a gas, so it makes it in the soil in a form ready for the plant. Studies have also shown that this bacteria has many beneficial properties for the growth and protection of the plant from pathogens and the importance of this bacteria and to try to shed light on its beneficial activities for the plant. The importance of this bacteria and the role of Azotobacter chroococcum in protecting plants from root rot diseases.
