Electrochemical Dinitrogen Fixation

Materials that catalyze efficient electrochemical N2 fixation would open up the possibility of using an N2/NH3 cycle to store and utilize energy from diffuse renewable sources. In such a cycle, N2 and H2O would be electrolytically transformed to NH3 and O2 in an electrolyzer powered by a renewable electricity source. With existing technologies, NH3 can be utilized in solid oxide fuel cells or c...

Dinitrogen Fixation in Illinois Bundleflower

Although Illinois bundleflower is known to contribute N in forage systems (Dovel et al., 1990; Posler et al., Symbiotic N2 fixation capacity may affect productivity of the peren1993; Springer et al., 2001), there is a paucity of informanial legume Illinois bundleflower [Desmanthus illinoensis (Michx.) tion on its N2 fixation capability. Nodulation has been MacMill. ex B.L. Rob. & Fernald]. Our ...

Biological Dinitrogen Fixation in Chaparral1

Microbiologist, Pacific Southwest Forest and Range Experiment Station, Forest Service, U.S. Department of Agriculture, Riverside, Calif. Abstract: Presently available data indicate that biological dinitrogen fixation is responsible for the greatest proportion of nitrogen entering chaparral ecosystems. Dinitrogen fixation by the Rhizobium-legume symbioses is relatively unimportant in chaparral w...

Dinitrogen fixation in male-sterile soybeans.

Partial male-sterile (ms(4)/ms(4)) soybeans (Glycine max L. Merr.) and their fertile isoline (Ms(4)/Ms(4)) were grown in adjoining field plots. From 62 until 92 days after emergence, the nitrogenase activity, assayed by acetylene reduction, of the average male-sterile plant was approximately twice that of the average fertile plant. At approximately 100 days after emergence, the assayable nitrog...
