Estimating Soil Compaction Risk at Regional Scales Using Meteorological Data and Soil Spectroscopy

Land Degradation &Development, EarlyView.
ABSTRACT Soil compaction is a significant form of soil degradation in Europe, reducing agricultural productivity, limiting carbon sequestration and increasing greenhouse gases emissions. In response, the forthcoming European Union Soil Monitoring and Resilience Law requires spatial assessment of topsoil and subsoil compaction risk at district, that is,

The nitrogen removal characterization and ecological risk assessment of Bacillus sp. isolated from mariculture systems in China with spatiotemporal difference.

PLoS ONE
The accumulation of nitrogen compounds may worsen the aquatic environment and cause serious economic losses in the aquaculture industry. In this study, the denitrification performance and ecological safety of 120 Bacillus sp.

Impact of Nitrogen Deposition on Carbon and Nitrogen Cycling in Peatlands Under Land‐Use Change

Land Degradation &Development, EarlyView.
ABSTRACT Increasing nitrogen (N) deposition significantly alters carbon and N dynamics in peatlands by affecting microbial processes, enhancing greenhouse gas emissions and nutrient leaching into adjacent waters. However, how peatland conversion for agriculture and forestry influences the fate of added N under elevated atmospheric deposition remains ...

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

Gongye 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.

Intermittent flooding of organic‐rich soil promotes the formation of denitrification hot moments and hot spots

Ecosphere, 2019
Anthropogenic activities have altered the nitrogen cycle, necessitating management on the landscape level. Isolated time periods and areas, termed hot moments and hot spots, respectively, frequently account for a large percentage of nitrate removal in ...

Combined nitrification-denitrification processes [PDF]

FEMS 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

Using a social‐ecological macrosystems framework to understand how human activities alter ecological synchrony

People and Nature, EarlyView.
Abstract Different aspects of ecological systems, biotic or abiotic, often fluctuate in coordinated patterns over space and time. Such high concordance between ecological processes is often referred to as ecological synchrony. Human activities, including and beyond climate change, have the potential to alter ecological synchrony by disrupting or ...

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

mLife, 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.

Recovering nutrients from urine – A golden opportunity for sustainable fertiliser production

PLANTS, PEOPLE, PLANET, EarlyView.
Agricultural industrialisation has led to levels of nutrients in the environment that are well above safe operating limits, yet fertiliser use is necessary to feed a growing population. The recovery of nutrients from human urine in large, developed cities may offset some of the ecological and economic impacts associated with fertiliser production, as ...

Implementing potential climate‐smart practices through diverse partnerships

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change is one of the greatest threats to society, negatively impacting agriculture and crop yields. Globally, agriculture is also one of the largest greenhouse gas (GHG) emitting sectors. Climate‐smart practices that are developed through diverse partnerships with scientists and practitioners are needed to decrease GHG emissions. We implemented
