DOI: 10.1016/j.ecoleng.2017.02.010
Abstract: Abstract Diazotrophs are one of the most important microbial communities which play a key role in rhizosphere to enhance plant growth-promotion by supplying fixed nitrogen to the plants. The aim of present study was to… read more here.

DOI: 10.1016/j.geoderma.2021.114999
Abstract: Abstract Excessive nitrogen (N) fertilization (ENF) and low utilization efficiency of fertilizer-derived N in high-input, high-yield cropping systems are serious ecological and economic problems in China. To examine the effects of long-term ENF on soil… read more here.

DOI: 10.1093/femsec/fiaa010
Abstract: ABSTRACT The McMurdo Dry Valleys (MDV) in Antarctica harbor a diverse assemblage of mat-forming diazotrophic cyanobacteria that play a key role in nitrogen cycling. Prior research showed that heterotrophic diazotrophs also make a substantial contribution… read more here.

DOI: 10.1111/1462-2920.16095
Abstract: Anthropogenic long-term nitrogen (N) deposition may dramatically impact biocrusts due to the overarching N limitation of soil biota in deserts. Even low levels of N may reach a critical loading threshold altering biocrust constituents and… read more here.

DOI: 10.1128/aem.00195-20
Abstract: The Amazon region is a major tropical forest region that is being deforested at an alarming rate to create space for cattle ranching and agriculture. Diazotrophs (nitrogen-fixing microorganisms) play an important role in supplying soil… read more here.

DOI: 10.3389/fmicb.2021.690200
Abstract: The ability of marine diazotrophs to fix dinitrogen gas (N2) is one of the most influential yet enigmatic processes in the ocean. With their activity diazotrophs support biological production by fixing about 100–200 Tg N/year… read more here.
