Biochars are increasingly used as soil amendment and for C sequestration in soils. The influence of feedstock differences pyrolysis temperature on biochar characteristics has been widely studied. However, there is a lack knowledge about the formation potentially toxic compounds that remain biochars after pyrolysis. We investigated from three feedstocks (wheat straw, poplar wood, spruce wood) were slowly pyrolyzed at 400, 460, 525°C 5 h (straw) 10 (woodchips), respectively. characterized...
Abstract Biochar (BC) application as a soil amendment has aroused much interest and was found to considerably improve nutrient status crop yields on poor, tropical soils. However, information the effect of BC temperate soils is still insufficient, with effects expected differ from We investigated dynamics, yield, quality in greenhouse pot experiment. compared three agricultural (Planosol, Cambisol, Chernozem), BCs different feedstocks (wheat straw [WS], mixed woodchips [WC], vineyard pruning...
Abstract Mountain regions are known to be especially vulnerable climatic changes; however, information on the climate sensitivity of alpine ecosystems is still scarce date. In this study, we investigate impacts and vegetation composition soil organic‐matter (SOM) stocks characteristics along an elevation gradient (900 1900 m asl) in Austrian Limestone Alps. The soils classified as Leptic Histosols, i.e. , organic directly overlying calcareous bedrock. Soil organic‐carbon (SOC; mean ±...
Phosphorus (P) fertilization is commonly based on soil testing, for which a variety of different P extraction methods are in use. The aim this study was to compare 14 terms their yield and relation properties. Fifty contrasting agricultural topsoils were sampled from Austria Germany. soils extracted with the following methods/extractants: H2O, CaCl2, LiCl, Olsen, Bray Kurtz II (Bray II), Mehlich 3, calcium-acetate-lactate (CAL), iron oxide impregnated filter papers (Fe-oxide Pi), cation...
Summary This study investigates (i) the effect of biochar amendments on soil microbial communities in temperate agricultural soils, (ii) involvement microorganisms ( MOs ) degradation and (iii) techniques to quantify short‐term experiments. The involved an incubation experiment a pot with two arable soils (a sandy acidic P lanosol calcareous loamy C hernozem) amended 13 ‐depleted from wheat husk willow plants. Phospholipid fatty acids PLFAs ), C‐PLFA , CO 2 C‐CO organic carbon org C‐C were...
Abstract. Geological sequestration of atmospheric carbon dioxide (CO2) can be achieved by the erosion organic (OC) from terrestrial biosphere and its burial in long-lived marine sediments. Rivers on mountain islands Oceania western Pacific have very high rates OC export to ocean, yet preservation offshore remains poorly constrained. Here we use content (Corg, %), radiocarbon (Δ 14Corg) stable isotope (δ13Corg) composition sediments Taiwan assess fate OC, using surface, sub-surface Holocene...
The benefits of biochar (BC) application to fertile, non-acidic soils in temperate climate regions might not always be as evident for highly weathered tropical soils. aim our study was investigate the effects BC on soil characteristics, nutrient uptake and crop yield field experiments two (Cambisol Chernozem) Austria. Maize wheat (Cambisol), barley sunflower (Chernozem) were grown successive vegetation periods following different rates (0, 24 72 t ha-1 at start experiment), supplemented with...
Biochar produced by pyrolysis of organic residues is increasingly used for soil amendment and many other applications. However, analytical methods its physical chemical characterization are yet far from being specifically adapted, optimized, standardized. Therefore, COST Action TD1107 conducted an interlaboratory comparison in which 22 laboratories 12 countries analyzed three different types biochar 38 physical–chemical parameters (macro- microelements, heavy metals, polycyclic aromatic...
The importance of wetlands in the global C budget has been recognized recent years, and high biomass productivity riverine floodplains is widely acknowledged. However, soil dynamics these ecosystems are still poorly understood rarely quantified. In this study, we quantify organic accretion examine changes matter pools across an age gradient floodplain soils under different land uses a warm temperate climate. We find rapid accumulation during initial 100 years formation, with rates exceeding...
Abstract Copper (Cu)-based fungicides have been used in viticulture to prevent downy mildew since the end of 19th century, and are still today reduce fungal diseases. Consequently, Cu has built up many vineyard soils, it is unclear how this affects soil functioning. The present study aimed assess short medium-term effects contamination on community. Two contrasting agricultural an acidic sandy loam alkaline silt loam, were for eco-toxicological greenhouse pot experiment. soils spiked with a...
Litter decomposition is an important process for cycling of nutrients in terrestrial ecosystems. The objective this study was to evaluate direct and indirect effects climate on litter along altitudinal gradient a temperate Alpine region. Foliar European beech (Fagus sylvatica) Black pine (Pinus nigra) incubated litterbags during two years the Hochschwab massif Northern Limestone Alps Austria. Eight incubation sites were selected following altitudinal/climatic transect from 1900 900 m asl....
Biochar application is a promising strategy for sequestering carbon in agricultural soils and improving degraded soils. Nonetheless, contradictory unsettled issues remain. This study investigates whether biochar influences the soil microbial biomass community structure using phospholipid fatty acid (PLFA) analysis. We monitored effects of four different types on communities three temperate Austria over several months. A greenhouse experiment two field experiments were conducted. The did not...
Fluvial sediment export from small mountainous rivers in Oceania has global biogeochemical significance affecting the turnover rate and of terrestrial carbon, which might be speeding up at recognized conditions increased rainfall intensity. In this study, historical runoff 16 major Taiwan are investigated separated into an early stage (1970–1989) a recent (1990–2010) to illustrate changes both export. The mean daily Island significantly by >80% with subtle increase runoff, indicating more...
