Hydrological N export from tropical forests in the Congo Basin

by Alexander Sedov | Nov 21, 2021 | Posters for INI2021, Posters for INI2021 – 5b. Biogeochemical N Cycle

Hydrological N export from tropical forests in the Congo Basin Nitrogen (N) budgets in tropical African forests show higher N inputs than outputs, however forests paradoxically appear to tightly cycle soil N. We try to compare the magnitude and seasonality of aquatic...

by Vladislav Sedov | May 27, 2021 | Posters for INI2021, Posters for INI2021 – 5b. Biogeochemical N Cycle

National Nitrogen Budget for Germany Objectives – Key questions▪ National Nitrogen Budgets (NNB) aims to quantify sources and fate of reactive nitrogen (Nr).▪ How much Nr is introduced into the nitrogen cycle eachyear in Germany?▪ Where does this Nr come from and...

Nitrogen budget estimation in the East Europe: A case study for Dniester and Prut catchments

by Vladislav Sedov | May 27, 2021 | Posters for INI2021, Posters for INI2021 – 5b. Biogeochemical N Cycle

Nitrogen budget estimation in the East Europe: A case study for Dniester and Prut catchments Agriculture, industry and other human activities have been altering Nitrogen ( cycling leading to N imbalance at ecosystem and regional levels. This results at numerous...

Assessment of Nitrogen and Carbon compounds emission as aftermath of wildfires in Dniester Delta

by Alexander Sedov | May 20, 2021 | Posters for INI2021, Posters for INI2021 – 5b. Biogeochemical N Cycle

Assessment of Nitrogen and Carbon compounds emission as aftermath of wildfires in Dniester Delta Reed-beds and aquatic plants are among main nitrogen (N) and carbon (C) depots in the Dniester Delta capable to accumulate up to 10-15% of N from total annual riverine...

Temporal dynamics of reactive nitrogen fluxes over different ecosystems

by Alexander Sedov | May 20, 2021 | Posters for INI2021, Posters for INI2021 – 5b. Biogeochemical N Cycle

Temporal dynamics of reactive nitrogen fluxes over different ecosystems Field campaigns were carried out to test novel measurement techniques in eddycovariance setups for continuous determination of NH3 and total reactive nitrogen fluxes.   While high-frequency...

The potential of ryegrass as cover crop to reduce soil N2O emissions

by Alexander Sedov | May 20, 2021 | Posters for INI2021, Posters for INI2021 – 5b. Biogeochemical N Cycle

The potential of ryegrass as cover crop to reduce soil N2O emissions In terrestrial ecosystems, nitrogen (N) fertilization of agricultural soils is themajor source of nitrous oxide (N2O) emissions.   Most of previous incubationexperiments did not include plants...
