Microbial quality of soil from the Pampa biome in response to different grazing pressures

Genetics and Molecular Biology, 2015
The aim of this study was to evaluate the impact of different grazing pressures on the activity and diversity of soil bacteria. We performed a long-term experiment in Eldorado do Sul, southern Brazil, that assessed three levels of grazing pressure: high ...

Comparison of the Total, Diazotrophic and Ammonia-Oxidizing Bacterial Communities Between Under Organic and Conventional Greenhouse Farming

Frontiers in Microbiology, 2020
Organic greenhouse farming is an innovative system that may maintain a high yield and healthy agroecosystem. There have been no rigorous studies on the comparison of total and nitrogen-cycling bacterial community in vegetable soils between organic and ...

EFFECTS OF SELECTED DIAZOTROPHS ON MAIZE GROWTH

Frontiers in Plant Science, 2016
Laboratory, greenhouse, and field experiments were conducted at the University of KwaZulu-Natal, Pietermaritzburg, South Africa in the 2010 2011 and 2011 2012 seasons to study the effects of eight strains of diazotrophic bacteria on the growth and yield ...

Depth-dependent influence of biochar application on the abundance and community structure of diazotrophic under sugarcane growth.

PLoS ONE, 2021
Despite progress in understanding diazotrophic distribution in surface soils, few studies have investigated the distribution of diazotrophic bacteria in deeper soil layers.

Temporal variability of diazotroph community composition in the upwelling region off NW Iberia. [PDF]

, 2019
Knowledge of the ecology of N2-fixing (diazotrophic) plankton is mainly limited to oligotrophic (sub)tropical oceans. However, diazotrophs are widely distributed and active throughout the global ocean.

Diazotrophic Bacterial Community of Degraded Pastures

Applied and Environmental Soil Science, 2017
Pasture degradation can cause changes in diazotrophic bacterial communities. Thus, this study aimed to evaluate the culturable and total diazotrophic bacterial community, associated with regions of the rhizosphere and roots of Brachiaria decumbens Stapf.

Phosphate solubilizing bacteria stimulate wheat rhizosphere and endosphere biological nitrogen fixation by improving phosphorus content [PDF]

PeerJ, 2020
Phosphate (P) availability often limits biological nitrogen fixation (BNF) by diazotrophic bacteria. In soil, only 0.1% of the total P is available for plant uptake.

Deep-Sea Archaea Fix and Share Nitrogen in Methane-Consuming Microbial Consortia [PDF]

, 2009
Nitrogen-fixing (diazotrophic) microorganisms regulate productivity in diverse ecosystems; however, the identities of diazotrophs are unknown in many oceanic environments. Using single-cell–resolution nanometer secondary ion mass spectrometry images of ^(
