The objective of this work was to measure the fluxes of N2O‑N and NH3‑N throughout the growing season of irrigated common‑bean (Phaseolus vulgaris), as affected by mulching and mineral fertilization. Fluxes of N2O‑N and NH3‑N were evaluated in areas with or without Congo signal grass mulching (Urochloa ruziziensis) or mineral fertilization. Fluxes of N were also measured in a native Cerrado area, which served as reference. Total N2O‑N and NH3‑N emissions were positively related to the increasing concentrations of moisture, ammonium, and nitrate in the crop system, within 0.5 m soil depth. Carbon content in the substrate and microbial biomass within 0.1 m soil depth were favoured by Congo signal grass and related to higher emissions of N2O‑N, regardless of N fertilization. Emission factors (N losses from the applied mineral nitrogen) for N2O‑N (0.01?0.02%) and NH3‑N (0.3?0.6%) were lower than the default value recognized by the Intergovernmental Panel on Climate Change. Mulch of Congo signal grass benefits N2O‑N emission regardless of N fertilization. |

Because of the environmental problems from global warming, the search for microorganisms that promote plant growth under drought and salt conditions is becoming inevitable. A Gram negative bacterium, resistant to 1M salt, gluconic acid and betaine producer and plant growth promoter was isolated from the Brazilian coast mangroves. By the phylogenetic analysis of the 16S rRNA, the strain was included in the taxonomic group of Pseudomonas. Hybridization with type strains and biochemical tests indicate that Pseudomonas strain is a new species. Thus, the name Pseudomonas aestus nov. sp. was proposed and the strain deposited in Embrapa Environment culture collection with the access code CMAA1215. |
