describe the role of nitrogen fixation in agriculture in detail
Answers
Diazotrophs are bacteria that contain nitrogenase, the enzyme responsible for biological nitrogen fixation (BNF). ... However, after the death of the plant, the fixed nitrogen is released, acting as a natural fertilizer for the soil and providing usable nitrogen to other plants (non-legumes).

Biological nitrogen fixation is an important process for agricultural productivity in many cropping systems because of direct inputs of atmospheric nitrogen, and rotational effects such as disease control.Nitrogen-fixing bacteria are microorganisms present in the soil or in plant roots that change nitrogen gases from the atmosphere into solid nitrogen compounds that plants can use in the soil.Two kinds of nitrogen-fixing bacteria are recognized. The first kind, the free-living (nonsymbiotic) bacteria, includes the cyanobacteria (or blue-green algae) Anabaena and Nostoc and genera such as Azotobacter, Beijerinckia, and Clostridium.Nitrogen is a component of chlorophyll and therefore essential for photosynthesis. It is also the basic element of plant and animal proteins, including the genetic material DNA and RNA, and is important in periods of rapid plant growth. Plants use nitrogen by absorbing either nitrate or ammonium ions through the roots.
