Biological N2 fixation by soybeans grown with or without liming on acid soils in a no-till integrated crop-livestock system

, 2021
Soil acidity can impair biological N2 fixation (BNF) and increase soybean (Glycine max L.) reliance on soil N to satisfy its plant N demand. This study aimed to evaluate the effect of liming, fertilization strategy, and grazing on: i) the N supplied via ...

Seasonal and Spatial Variability of Biological N2 Fixation in a Cool Temperate Bog

Journal of Geophysical Research: Biogeosciences, 2022
Northern peatlands are globally important carbon (C) and nitrogen (N) sinks due to slow decomposition rates resulting in long‐term organic matter accumulation. Despite their large N storage, peatlands depend on sources of bio‐available N to sustain their

Changes in the biological N2-fixation rates and diazotrophic community as vegetation recovers on abandoned farmland in a karst region of China

, 2021
The successful regeneration of karst landscapes that have been severely degraded by intensive agriculture relies on the recovery of biological nitrogen fixation (BNF) by diazotrophic communities in soils after nitrogen (N) derived from synthetic ...

Acetylene reduction (N2-fixation) by Enterobacteriaceae isolated from industrial wastewaters and biological treatment systems

Applied Microbiology and Biotechnology, 1985
Acetylene reducing (N2-fixing) Entero-bacteriaceae have been isolated from activated sludge plants treating waste from the paper and food industries (103 to 106 cells per ml) and from composting plants handling forest waste (105 to 106 cells per g wet weight).

Variations in the 15N natural abundance of plant-available N with soil depth: Their influence on estimates of contributions of biological N2 fixation to sugar cane

, 2014
The objective of this study was to investigate the application of the 15N natural abundance technique to quantify BNF inputs to different varieties of field-grown sugarcane. The experiment was planted on a low-fertility sandy soil and no N fertilizer was

Biological N2-fixation by three tropical forage legumes and its transfer to Brachiaria humidicola in mixed swards

Soil Biology and Biochemistry, 1997
Abstract A study was conducted (a) to determine the biological N 2 -fixation (BNF) by three tropical pasture legumes ( Centrosema pubescens, Stylosanthes hamata and Pueraria phaseoloides ) grown in monoculture and associated with the grass Brachiaria humidicola ; and (b) to assess the potential transfer of fixed N from the legume to the companion ...

[Applied gene technology using biological N2-fixation for an example (author's transl)].

Arzneimittel-Forschung, 1980
About biological nitrogen fixation most information on the genetic and enzymatic level is known from investigations with Klebsiella pneumoniae. The gene region for N2-fixation (nif) was transferred from K.pneumoniae to the enterobacterium Escherichia coli. After acquisition of nif E.coli is able to fix nitrogen.

Contribution of N2 fixation to biological productivity along a meridional transect in the Eastern Atlantic Ocean

2015
Biological nitrogen fixation is now widely acknowledged as the dominant source of new nitrogen for oligotrophic pelagic marine ecosystems with minor though significant contributions from riverine and atmospheric inputs (Capone et al., 1997; Karl et al., 2002; Codispoti et al., 2007).
