Dentrifing bacterias are enemies for the farmers justify your answer
Answers
Denitrifying bacteria themselves include several species of Pseudomonas, Alkaligenes , Bacillus and others. By their activity the losses of nitrogen into the atmosphere is roughly balanced by that which is released into the soil by nitrifying bacteria, forming a relatively balanced cycle. so they are harmful to crop.
Denitrification occurs when soil bacteria use nitrate for their respira- tion in the place of oxygen in the air. This process occurs most rapidly in warm, wet soils with an abundance of nitrate. Presence of Nitrate: Denitrification only occurs when nitrate is present
denitrificans, Micrococcus denitrificans, and some species of Serratia, Pseudomonas, and Achromobacter are implicated as denitrifiers. Pseudomonas aeruginosa can, under anaerobic conditions (as in swampy or water-logged soils), reduce the amount of fixed nitrogen (as fertilizer) by up to 50 percent.
