1 day ago · The significance of nitrogen fixation extends beyond the plant-microbe symbiosis. It supports plant growth, which sustains herbivores and higher trophic levels. In agriculture, nitrogen-fixing crops can enhance soil fertility and reduce the need for synthetic fertilizers, offering an environmentally friendly and economically beneficial approach.
18 hours ago · Nitrogen fixation by diazotrophs within North Atlantic eddies, especially near the edges of the mesoscale structures, is a key component of the North Atlantic marine nitrogen cycle, according to ...
5 days ago · Nitrogen-fixing is the process of converting inert atmospheric nitrogen (N₂) into ammonia (NH₃) or related compounds that are more accessible to plants.
1 day ago · Nitrogen fixation can be chemically divided into two primary pathways: reduction and oxidation represented by Haber-Bosch (HB) and by Birkland-Eyde (BE) process, respectively. The reduction of nitrogen with hydrogen over catalysts is the basis of the well-known HB process, which has been used for a large scale NH 3 production (>3000 ton-NH 3 /d) for more than a century.
1 day ago · Nitrogen oxides may further react with atmospheric water to form nitric acid (HNO 3), which may act as a soil fertilizer on the earth's surface via reduction of NO 3 − to NO 2 − and NH 4 + by humic substances. 42 (ii) The second route consists on the biological N 2 fixation into terrestrial and marine ecosystems by nitrogen fixing microorganisms (bacteria and archaea).
Oct 3, 2024 · This article presents a one-step nitrogen fixation (NF) process using ethanol solution and nitrogen as raw materials and a magnetic field stabilized glow discharge (MSGD) as a plasma reactor, in which the plasma is stabilized at a fixed position under the opposing forces of the Lorentz force and airflow.
Sep 13, 2024 · Nitrogen fixation, the conversion of nitrogen gas into inorganic nitrogen substances, is primarily (90%) performed by specific bacteria and blue-green algae. A far lesser amount of free nitrogen is fixed abiotically (through lightning, ultraviolet radiation, and electrical equipment) and in the Haber-Bosch process.
