Florida Carpon Desmodium
... desmodium can also add nitrogen to the system. Biologically fixed nitrogen in a moderately grazed mixture with bahiagrass normally ranges from the equivalent of 30 to 75 lb/A of nitrogen. Nitrogen fixation by carpon desmodium can be negligible if it is continuously heavily grazed or receives nitrogen fertilization. Carpon adds quality to normal ...

... symbioses with nitrogen fixing cyanobacteria (formerly known as the blue-green algae). Cycads provide fixed carbon and a stable environment to the cyanobacteria in exchange for fixed nitrogen. These ... Cycads have the ability to fix nitrogen. Biologically fixed nitrogen makes up 90% of the nitrogen available globally for use by plants and animals. Nitrogen is an important component of many ...

... is involved in plant cell plate formation. Second, we are attempting to understand how symbiotically fixed nitrogen is assimilated in the host cell. The glutamine formed as a result of primary assimilation ... is funneled into purine biosynthesis pathway which is considered to be induced on commencement of nitrogen fixation. By cloning the first regulatory gene of this pathway, PRPP­AT, we ...

... use. This process is often referred to as "nitrogen fixation" or "fixing nitrogen." When the legume dies and its roots begin to decompose, residual nitrogen becomes available to other plants. Most soils in ... you buy the legume seed, to ensure that fixation occurs. In order to accumulate enough fixed nitrogen in the soil to nourish future plants, leguminous cover crops would have to be grown ...
