Open AccessFates of slurry-nitrogen applied to mountain grasslands: the importance of dinitrogen emissions versus plant N uptake
Intensive fertilization of grasslands with cattle slurry can cause high environmental nitrogen (N) losses in form of ammonia (NH3), nitrous oxide (N2O), and nitrate (NO3−) leaching. Still, knowledge on short-term...

Open AccessDivergent drivers of the spatial variation in greenhouse gas concentrations and fluxes along the Rhine River and the Mittelland Canal in Germany
Lotic ecosystems are sources of greenhouse gases (GHGs) to the atmosphere, but their emissions are uncertain due to longitudinal GHG heterogeneities associated with point source pollution from anthropogenic ac...

Open AccessA redistribution of nitrogen fertiliser across global croplands can help achieve food security within environmental boundaries
A major societal challenge is to produce sufficient food for a growing global population while simultaneously reducing agricultural nitrogen pollution to within safe environmental boundaries. Here we use spati...

Context-specific assessments of carbon footprints of the rice value chain: from product labeling to potential mitigation impacts
This study presents three contrasting applications using calculation tools for greenhouse gas (GHG) emissions and carbon footprints (C-footprint) that were specifically developed for rice production. This incl...

Integrated biochar solutions can achieve carbon-neutral staple crop production
Agricultural food production is a main driver of global greenhouse gas emissions, with unclear pathways towards carbon neutrality. Here, through a comprehensive life-cycle assessment using data from China, we ...

Open AccessImpacts of slurry acidification and injection on fertilizer nitrogen fates in grassland
Low nitrogen (N) use efficiency of broadcast slurry application leads to nutrient losses, air and water pollution, greenhouse gas emissions and—in particular in a warming climate—to soil N mining. Here we test...

Species richness is more important for ecosystem functioning than species turnover along an elevational gradient
Many experiments have shown that biodiversity enhances ecosystem functioning. However, we have little understanding of how environmental heterogeneity shapes the effect of diversity on ecosystem functioning an...

Open AccessBiotic and abiotic controls on carbon storage in aggregates in calcareous alpine and prealpine grassland soils
Alpine and prealpine grasslands provide various ecosystem services and are hotspots for the storage of soil organic C (SOC) in Central Europe. Yet, information about aggregate-related SOC storage and its contr...

Open AccessIntensive slurry management and climate change promote nitrogen mining from organic matter-rich montane grassland soils
Consequences of climate change and land use intensification on the nitrogen (N) cycle of organic-matter rich grassland soils in the alpine region remain poorly understood. We aimed to identify fates of fertili...

Open AccessDinitrogen (N2) pulse emissions during freeze-thaw cycles from montane grassland soil
Short-lived pulses of soil nitrous oxide (N2O) emissions during freeze-thaw periods can dominate annual cumulative N2O fluxes from temperate managed and natural soils. However, the effects of freeze thaw cycles (...

Open AccessLivestock enclosures in drylands of Sub-Saharan Africa are overlooked hotspots of N2O emissions
Sub-Saharan Africa (SSA) is home to approximately ¼ of the global livestock population, which in the last 60 years has increased by factors of 2.5–4 times for cattle, goats and sheep. An important resource for...

Seasonal dynamics and profiles of soil NO concentrations in a temperate forest
Soils are known to be significant sources of atmospheric nitric oxide (NO), a key compound in atmospheric chemistry. NO is a key regulating substance for inter- and intra-species signalling and competition and...

Dissolved organic carbon leaching from montane grasslands under contrasting climate, soil and management conditions
Grasslands are thought to be more vulnerable than many other ecosystems to climate change since their soils are characterized by high organic carbon contents and warming in montane regions is twice the global ...

Open AccessDinitrogen emissions: an overlooked key component of the N balance of montane grasslands
While emissions of nitric oxide (NO), ammonia (NH3) and nitrous oxide (N2O) from grassland soils have been increasingly well constrained, soil dinitrogen (N2) emissions are poorly understood. However, N2 losses m...
