The response of soil organic matter (OM) decomposition to increasing temperature is a critical aspect ecosystem responses global change. impacts climate warming on dynamics have not been resolved due apparently contradictory results from field and lab experiments, most which has focused labile carbon with short turnover times. But the majority total stocks are comprised times decades centuries. Understanding these pools change essential for forecasting longer-term changes in storage. Herein,...
Land-use change (LUC) is a major driving factor for the balance of soil organic carbon (SOC) stocks and global cycle. The temporal dynamic SOC after LUC especially important in temperate systems with long reaction time. On basis 95 compiled studies covering 322 sites zone, response functions (CRFs) were derived to model five different types (mean depth 30±6 cm). Grassland establishment caused lasting sink relative stock 128±23% afforestation on former cropland 116±54%, 100 years (mean±95%...
Abstract Soil carbon sequestration and avoidable emissions through peatland restoration are both strategies to tackle climate change. Here we compare their potential environmental costs regarding nitrogen land demand. In the event that no further areas exploited, drained peatlands will cumulatively release 80.8 Gt 2.3 nitrogen. This corresponds a contemporary annual greenhouse gas emission of 1.91 (0.31–3.38) CO 2 -eq. could be saved with restoration. on all agricultural has comparable...
Summary Understanding the response of soil organic carbon (SOC) to environmental and management factors is necessary for estimating potential soils sequester atmospheric carbon. Changes over time in amount distribution SOC fractions with different turnover rates can be estimated by means models such as RothC, which typically consider two five pools. Ideally, these pools should correspond measurable fractions. The aim this study was test relationship between used RothC separated through a...
Abstract. Soil dust is a major driver of ice nucleation in clouds leading to precipitation. It consists largely mineral particles with small fraction organic matter constituted mainly remains micro-organisms that participated degrading plant debris before their own decay. Some have been shown be much better nuclei than the most efficient soil mineral. Yet, current aerosol schemes global climate models do not consider difference between and terms activity. Here, we show from clay silt size...
Biochar is increasingly promoted as a beneficial soil conditioner. However, it may contain residues of polycyclic aromatic hydrocarbons (PAHs) result its production by pyrolysis. To date, analytical methods to analyze PAHs in biochar quantitatively are hardly available. This study presents an optimized and validated procedure quantify the 16 U.S. EPA biochar. were best extracted with Soxhlet for 36 h using 100% toluene. Average absolute recoveries isotope labeled internal standards used each...
Abstract Peatlands cover only about 3% the global land area, but store twice as much carbon forest biomass. If intact peatlands are drained for agriculture or other human uses, peat oxidation can result in considerable CO 2 emissions and greenhouse gases (GHG) decades even centuries. Despite their importance, from degraded have so far not been included explicitly mitigation pathways compatible with Paris Agreement. Such include land-demanding options like bioenergy afforestation substantial...
