The Effect of Synthetic Cow Urine on Microorganisms and Their Potential Phosphorus Mining Activity in Rhizosphere and Bulk Soil

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background and aims Soil microbes adapt to varying nutrient inputs by modifying their utilization strategies, with root exudates and animal urine serving as key carbon (C) and nutrient sources in grasslands. Nonetheless, the specific mechanisms by which cow urine and root exudates influence microbial community and resource utilization remain ...

Screening and nitrogen removal characteristics of a denitrifying bacteria suitable for partial denitrification

open access: yesGongye shui chuli
A strain D5 with excellent partial denitrification performance was screened from paddy soil. The bacteria were identified as Klebsiella pneumoniae by morphological observation and 16S r DNA sequence analysis.

Comparative genomic analysis of Thermus provides insights into the evolutionary history of an incomplete denitrification pathway

open access: yesmLife, 2022
Biological denitrification is a crucial process in the nitrogen biogeochemical cycle, and Thermus has been reported to be a significant heterotrophic denitrifier in terrestrial geothermal environments.

Combined nitrification-denitrification processes [PDF]

open access: yesFEMS Microbiology Reviews, 1994
Nitrification and denitrification have traditionally been regarded as essentially separate phenomena, carried out by different bacteria in segregated areas of soil, sediments, water or reactors. However, research in the 1980s and 1990s has established that nitrifiers and denitrifiers are not as metabolically fastidious as previously thought, and strict

Effects of aquatic vegetation type on denitrification [PDF]

open access: yes
In a microcosm 15N enrichment experiment we tested the effect of floating vegetation (Lemna sp.) and submerged vegetation (Elodea nuttallii) on denitrification rates, and compared it to systems without macrophytes.

Nutrients, Metals, and Carbon in Soils Irrigated With Treated Versus Untreated Wastewater

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
Transitioning from untreated to treated wastewater irrigation reduced soluble N and P but enhanced Cr, Fe and Ni mobilization in long‐term wastewater‐irrigated Mezquital Valley soils, highlighting soil‐type‐dependent effects. ABSTRACT Background Reuse of wastewater for irrigation can mitigate pressure on water resources and support closing nutrient ...

Coupled anoxic nitrification/manganese reduction in marine sediments [PDF]

open access: yes, 1999
Pore water and solid phase distributions of oxygen, manganese, and nitrogen from hemipelagic and shelf sediments sometimes indicate a close coupling between the manganese and nitrogen redox cycles.

Looking back to look ahead: a vision for soil denitrification research.

open access: yesEcology, 2019
Denitrification plays a critical role in regulating ecosystem nutrient availability and anthropogenic reactive nitrogen (N) production. Its importance has inspired an increasing number of studies, yet it remains the most poorly constrained term in ...

Revisiting the Effectiveness of Nitrification Inhibitors Under Different Soil Moisture Conditions and Mineral Nitrogen Extraction Methods: Further Experimental Work Considering the Pasda et al. (2023) Opinion Paper

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background In a recent opinion article, Pasda et al. indicated that the findings from our previous study (Guo et al.) were misleading due to the inappropriateness of the experimental work. The mentioned study focused on the effectiveness of four nitrification inhibitors (NIs) in reducing nitrous oxide (N2O) emissions as affected by temperature

Denitrification potential of riparian sediments amended with

open access: yesJournal of Ecology and Environment, 2014
Denitrification permanently removes nitrate from aquatic ecosystems, so construction of denitrification walls to enhance denitrification activity is often suggested to reduce the nitrate levels from tributary ecosystems.
