Read this article to learn about the role of nitrogen in the life of the plants and different sources of nitrogen to plants. Role of Nitrogen in Plants: Nitrogen is a universally occurring element in all the living beings. Apart from water and mineral salts the next major substance in plant cell is protein (about 10-12% of the cell). These [...]
Let us make an in-depth study of the conversion of nitrate into ammonia by the plants. Nitrogen in nitrate (NO3-) is present in highly oxidised state while in ammonia in reduced form. Therefore, the conversion of nitrate to ammonia is a reductive process. Reduction of nitrate to ammonia takes place in many steps which are mediated by specific enzymes. At [...]
Biological Nitrogen Fixation: Conversion of molecular nitrogen (N2) of the atmosphere into inorganic nitrogenous compounds such as nitrates or ammonia is called as nitrogen fixation. When this nitrogen fixation occurs through the agency of some living organisms, the process is called as biological nitrogen fixation in which atmospheric nitrogen is converted into ammonia. An estimated 190 × 1012 gm per [...]
