The 25 pages that link to Biological nitrogen fixation, each with the reason it gives.

• Nitrogen fixationBroader topic: It is the biological route that supplies fixed nitrogen to ecosystems.

• Soil fertilityRelated: It supplies new nitrogen to soils, especially through associations involving legumes.

• Biogeochemical cycleRelated: It is a key biological route by which nitrogen enters food webs.

• FabaceaeRelated: Legume-based crop rotations can add biologically fixed nitrogen to agricultural soils.

• SymbiosisRelated: Symbiotic nitrogen fixation supports plant growth and agricultural fertility.

• RhizobiumNarrower topic: Rhizobium is a major agricultural example of this natural source of reactive nitrogen.

• Nitrogen fertilizerCompared with: It supplies nitrogen through microbial activity rather than manufactured fertilizer.

• Root noduleNarrower topic: Root nodules are major sites of biological nitrogen fixation in agriculture.

• SoybeanRelated: Soybean roots host bacteria that supply nitrogen to the plant through this process.

• AcaciaRelated: Root-associated bacteria enable many acacias to add usable nitrogen to nutrient-poor soils.

• Plant nutritionCompared with: Plants cannot fix atmospheric nitrogen themselves, but symbioses with nitrogen-fixing microbes can supply usable nitrogen.

• Soil microbiologyRelated: Understanding this process helps manage legume–microbe partnerships and nitrogen inputs to soils.

• NitrogenaseNarrower topic: Nitrogenase is the enzyme system that performs this conversion.

• AlfalfaRelated: Alfalfa’s symbiosis can reduce reliance on synthetic nitrogen fertilizer in crop rotations.

• FrankiaRelated: Frankia is one of the bacterial groups used in biological nitrogen fixation.

• Tropical agricultureRelated: Legumes and their microbial partners can supply nitrogen where fertilizer is costly or scarce.

• Agricultural chemistryRelated: It adds reactive nitrogen to agricultural systems without industrial ammonia synthesis.

• AzollaNarrower topic: It explains how Azolla gains nitrogen without relying solely on dissolved nutrients.

• Pigeon peaRelated: Pigeon pea gains usable nitrogen through symbiosis with soil bacteria.

• Phaseolus vulgarisRelated: Root-nodule bacteria can supply common bean with nitrogen and influence its value in crop rotations.

• SalvinialesNarrower topic: Azolla's cyanobacterial partner makes this ecosystem service available in cultivated fields.

• RhizobiaNarrower topic: Rhizobia are prominent agents of this broader natural nitrogen input.

• Vicia fabaRelated: Root-associated bacteria supply nitrogen that can support faba bean growth.

• Acacia decurrensRelated: Nitrogen inputs from black wattle can alter nutrient-poor ecosystems where it invades.

• Alnus rubraBroader topic: Frankia bacteria perform this process inside red alder's root nodules.
