On-farm effects of urease and nitrification inhibitors on resource use, soil C and climate impactNARA Subscribed
Efficient nitrogen (N) use in crops is vital for promoting sustainable and profitable agriculture and has significant implications for greenhouse gas (GHG) mitigation. While urease (UI) and nitrification inhibitors (NI) are known to influence N transformations, soil N availability, and N utilization efficiency (NUE) in ammonium sulfate urea (AS-HS), their impacts on the carbon (C) and water cycles are less well understood. To...
CO2 and N2O Emissions after Digestate Application Responded Differently to Topsoil Dilution and Soil Erosion StateNARA Subscribed
The application of digestates supports soil fertility by restoring soil organic matter (SOM) and supplying nitrogen (N). However, their application can increase greenhouse gas (GHG) emissions from agriculture. Targeted digestate application to soils where erosion has mixed subsoil into topsoil may reduce emissions, as the lower SOM saturation in this diluted topsoil could enhance stabilization of organic inputs. This study inv...
Drainage and agricultural use transform natural peatlands from a net carbon (C) sink to a net C source. Rewetting of peatlands, despite of high methane (CH 4 ) emissions, holds the potential to mitigate climate change by greatly reducing CO 2 emissions. However, the time span for this transition is unknown because most studies are limited to a few years. Especially, nonpermanent open water areas often created after rewetting,...
There are few data on mortality after discharge with community-acquired pneumonia (CAP). Therefore, we evaluated risk factors for 30-day post-discharge mortality after CAP. We included all patients of the prospective multi-national CAPNETZ study between 2002 and 2018 with (1) hospitalized CAP, (2) survival until discharge, and (3) complete follow-up data. The study endpoint was death within 30 days after discharge. We evaluate...
Drainage has turned peatlands from a carbon sink into one of the world's largest greenhouse gas ( GHG ) sources from cultivated soils. We analyzed a unique data set (12 peatlands, 48 sites and 122 annual budgets) of mainly unpublished GHG emissions from grasslands on bog and fen peat as well as other soils rich in soil organic carbon ( SOC ) in Germany. Emissions and environmental variables were measured with identical methods...
