Przykłady nitrogen fixation

• Therefore, nitrogen fixation is unimportant as a source of this element for savanna plants.

• These hypotheses will be tested as additional genomic, biochemical and geological evidence sheds more light on the evolution of nitrogen fixation, photosynthesis and cyanobacteria.

• The objective of the present experiment was to assess seed composition and nitrogen fixation under these conditions.

• Thus, at this point, the phylogenetic and molecular evidence indicate that nitrogen fixation arose before photosynthesis, but more work on this question is needed.

• The evolution of nitrogen fixation also appears to have been a precondition for the evolution of (bacterio)chlorophyll-based photosynthesis.

• This model involves the interplay of denitrification, nitrification and nitrogen fixation, but does not explicitly consider the influence of tracemetal availability for requisite enzyme activity.

• By providing soil cover and nitrogen fixation they not only improve livestock feed but also help prevent soil degradation.

• These results indicate that brassica residues could affect critical microbial processes, including nitrification, nitrogen fixation and mycorrhizal symbioses.

• Technologies include nitrogen fixation, biocontrol of pathogens and pests, fermentation, post harvest microbiology and more.

• Stabilizing agricultural energy needs: role of forages, rotations, and nitrogen fixation.

• Nitrogen fixation throughout growth, and varietal differences in nitrogen fixation by the rhizosphere of rice planted in pots.

• Can biological nitrogen fixation sustain agriculture in the tropics?

• The acetylene reduction assay for measuring nitrogen fixation in waterlogged soil.

• It appears that nitrogen fixation is more sensitive to infection than nitrogen assimilation.

• So, for example, several species will typically perform nitrogen fixation functions, but each will perform those functions differently depending upon climatic conditions.
