Fixation of Nitrogen by the Rice PlantAPPRECIABLE work has been done by P. K. De 1 , Uppal et al. 2 and Chaudhuri H. 3 on the fixation of nitrogen by blue-green alg in rice soil. Further work by Watanabe et al. 4 revealed that some specific alg fix nitrogen in rice soil. ...
It is primarily concerned with the microbiology of the free-living nitrogen-fixing organisms, although casual reference to symbiotic systems has been made. With this in mind, I shall attempt not to burden the reader with microbiological minutiae but will restrict coverage to those biological aspects...
Define fixations. fixations synonyms, fixations pronunciation, fixations translation, English dictionary definition of fixations. n. 1. The act or process of fixing or fixating: the fixation of nitrogen by bacteria. 2. An obsessive preoccupation. 3. Psyc
Nitrogen is fixed, or combined, in nature as nitric oxide bylightning and ultraviolet rays, but more significant amounts of nitrogen are fixed as ammonia, nitrites, and nitrates by soil microorganisms. ... Within the nodules, the bacteria convert free nitrogen to ammonia, which the host plant ...
The metabolic capacity for nitrogen fixation is known to be present in several prokaryotic species scattered across taxonomic groups. Experimental detection of nitrogen fixation in microbes requires species-specific conditions, making it difficult to obt
Rhizobium is a soil bacteria that fix nitrogen found at root nodules of legumes. Explore more on the role of rhizobium in agriculture and more on related topics at BYJU'S
a.the conversion of nitrogen in the air into a compound, esp a fertilizer b.the conversion of a free element into one of its compounds 3.the reduction of a substance from a volatile or fluid form to a nonvolatile or solid form
Bacterial nitrogen fixation is the biological process by which atmospheric nitrogen is uptaken by bacteroids located in plant root nodules and converted into ammonium through the enzymatic activity of nitrogenase. In practice, this biological process serves as a natural form of fertilization and its opt...

However, it did so only during the first year because the introduced ineffective strains were overgrown by effective strains in the second year. Hence, ryegrass without nitrogen fertilizer was a better measure of the amounts of nitrogen obtainable from the soil. Estimates of fixation ranged from ...
