The hydroclimate of South America is characterized by the South American summer monsoon (SASM), a tropical atmospheric circulation that induces a summer precipitation regime, and the Southern Hemisphere Westerlies (SHW), an extratropical atmospheric

Abstract Oxygen isotope records of cushion‐plant peat cellulose from the southern central Andes capture evidence for significant environmental changes. We observe that the δ18Ocell peatland record from Cerro Tuzgle (24°S) is in high conformity wi

Improving nitrogen retention of cattle slurry with oxidized biochar: An incubation study with three different soils

Autor: Xinyue Cao, Rüdiger Reichel, Holger Wissel, Nicolas Brüggemann

Publikováno v: Journal of environmental quality 52(1), 1-12 (2023). doi:10.1002/jeq2.20424

The application of livestock slurry in soils can lead to nitrogen (N) losses through ammonia (NH3) emission or nitrate (NO3−) leaching. Oxidized biochar has great potential to mitigate N losses due to its strong adsorption capacity; however, the ef

The effect of different high carbon soil amendments on N retention capacity under winter conditions in silty clay soil with low organic carbon content: An incubation study

Autor: Kerui Zhao, Rüdiger Reichel, Holger Wissel, Nicolas Brüggemann

Average soil temperatures in winter in Germany are frequently between 0 and +10℃, usually at high soil moisture levels. Therefore, the decomposition of soil organic matter and soil nitrogen (N) cycling are still active and could be substantial unde
