Legumes harbor nitrogen-fixing bacteria and are therefore good crops to grow to replenish the soil. Most nitrogen fixation occurs naturally, in the soil, by bacteria.
Nitrogen fixation and exchange of form that occurs in the soil. Some bacteria attach to plant roots and have a symbiotic relationship that is beneficial to both the plant and the bacteria with the plant. Nitrogen fixing bacteria accomplish more than 90 percent of all nitrogen fixation and therefore play an important role in the nitrogen cycle. processes that can fix nitrogen atmospheric, be process and biological. Atmospheric fixation occurs when the high temperature of lightning splits nitrogen gas so that it unites with oxygen and moisture in the air to form nitrates that fall to the ground. Nitrogen fixation occurs among some termites and fungi. It occurs naturally in the air through the production of NOx by lightning. All biological reactions that involve the process of nitrogen fixation are catalyzed by enzymes called nitrogenases.
