The use of nitrogen compounds from organic waste

by Alexander Sedov | May 24, 2021 | Abstracts for INI2021, Abstracts for INI2021 – 5b. Biogeochemical N Cycle

The use of nitrogen compounds from organic waste Organic waste (e.g., food waste) contains nitrogen compounds, which were initially considered for human consumption. In recent years, microbial processes have been presented, which considered the use of organic nitrogen...

Terrestrial denitrification and nitrous oxide emissions: global estimates and uncertainties

by Alexander Sedov | May 24, 2021 | Abstracts for INI2021, Abstracts for INI2021 – 5b. Biogeochemical N Cycle

Terrestrial denitrification and nitrous oxide emissions: global estimates and uncertainties Synthetic N fertilizer use has grown exponentially causing severe environmental consequences. Most reactive nitrogen (Nr) is ultimately removed by denitrification, however...

by Alexander Sedov | May 24, 2021 | Abstracts for INI2021, Abstracts for INI2021 – 5b. Biogeochemical N Cycle

Managing reactive nitrogen in agricultural systems under future conditions in Austria The recently funded NitroClim.AT project will provide a cost estimate of agricultural management strategies for Austrian agricultural systems that minimize Nr losses to surface water...

Integrated control and modeling of denitrification in Agricultural Soils at various scales

by Alexander Sedov | May 24, 2021 | Abstracts for INI2021, Abstracts for INI2021 – 5b. Biogeochemical N Cycle

Integrated control and modeling of denitrification in Agricultural Soils at various scales Denitrification, the process of nitrate reduction allowing microbes to sustain respiration under anaerobic conditions, is the key process returning reactive nitrogen as N2 to...

The dynamics of ammonia bi-directional exchange above agricultural crops

by Alexander Sedov | May 24, 2021 | Abstracts for INI2021, Abstracts for INI2021 – 5b. Biogeochemical N Cycle

The dynamics of ammonia bi-directional exchange above agricultural crops Significant uncertainties exist in ammonia (NH3) emissions from crop fields, which is relevant for the environmental impact of fertilizers. To better understand NH3 bi-directional exchange in...

Satellite monitoring of ammonia: from point sources to long-term trends

by Alexander Sedov | May 24, 2021 | Abstracts for INI2021, Abstracts for INI2021 – 5b. Biogeochemical N Cycle

Satellite monitoring of ammonia: from point sources to long-term trends IASI satellite NH3 measurements are used to identify, categorise and quantify world’s NH3 emission hotspots. In particular, using spatial oversampling and supersampling techniques, we are...
