Biochar properties vary, and characterization of biochars is necessary for assessing their potential to sequester carbon improve soil functions. This study aimed at key surface agronomic relevance products from slow pyrolysis 250-800 °C, hydrothermal carbonization (HTC), flash carbonization. The further relating current indicators. results suggest that biochar chemical composition can be inferred volatile matter (VM) consistent corncob miscanthus feedstocks the three tested production...
Biochar is a carbon-rich solid product obtained by pyrolysis of biomass. Here, we investigated multiple biochars produced under slow (235–800 °C), flash carbonization, and hydrothermal carbonization (HTC), using Scanning Electron Microscope—Energy Dispersive X-ray Spectroscopy (SEM-EDX) in order to determine whether SEM-EDX can be used as proxy characterize effectively. Morphological analysis showed that feedstock has an integrated structure compared biochar; more pores were generated, the...
Biochar and its properties can be significantly altered according to how it is produced, this has ramifications towards biochar behaves once added soil. We produced biochars from corncob miscanthus straw via different methods (slow pyrolysis, hydrothermal flash carbonization) temperatures assess carbon cycling soil microbial communities were affected. Mineralization of biochar, parent feedstock, native organic matter monitored using 13C natural abundance during a 1-year lab incubation....
Abstract Biochar is a carbon (C)‐rich material produced from biomass by anoxic or oxygen‐limited thermal treatment known as pyrolysis. Despite substantial gaseous losses of C during pyrolysis, incorporating biochar in soil has been suggested an effective long‐term option to sequester CO 2 for climate change mitigation, due the intrinsic stability C. However, no universally applicable approach that combines quality and pyrolysis yield into overall metric sequestration efficiency yet. To...
Key priorities in biochar research for future guidance of sustainable policy development have been identified by expert assessment within the COST Action TD1107. The current level scientific understanding (LOSU) regarding consequences application to soil were explored. Five broad thematic areas addressed: biodiversity and ecotoxicology, organic matter greenhouse gas (GHG) emissions, physical properties, nutrient cycles crop production, remediation. highest biochar’s effects soils were:...
Biochar has been shown to reduce nitrous oxide (N2O) emissions from soils, but the effect is highly variable across studies and mechanisms are under debate. To improve our mechanistic understanding of biochar effects on N2O emission, we monitored kinetics NO, N2 accumulation in anoxic slurries a peat mineral soil, spiked with nitrate amended feedstock dried at 105 °C produced 372, 416, 562 796 five different doses. Both soils accumulated consistently less NO presence high-temperature chars...
Biochar, which is the product of biomass pyrolysis, has been suggested as a feed supplement to improve performance in livestock systems and reduce greenhouse gas (GHG) emissions. The aim current study was investigate vitro vivo potential biochar favourably modify rumen fermentation (e.g., an increase total Short Chained Fatty Acid (SCFA) concentration change SCFA profile), methane emission sheep growth performance. Four concentrates were produced with inclusion 0, 10, 23 46 g/kg DM....
ABSTRACT The potential for soil carbon (C) sequestration strongly depends on the availability of plant biomass inputs, making its efficient use critical designing net zero strategies. Here, we compared different processing pathways and quantified long‐term effect resulting exogenous organic materials (EOMs) to that direct residue input (SOC) storage. We estimated C losses during feed digestion material, storage manure, composting anaerobic material pyrolysis using values reported in...

Decomposition and stabilization of organic C in soils different cultivation systemsSoil carbon (SOC) is an important component the global stock, supports functions related to soil health. It therefore great importance that we invest new methodologies research on increasing SOC stocks globally. On a farm-level, conservation agriculture aims manage content by, for example, using cover crops, crop rotations or minimal tillage.  The aim our study investigate sequestration...
Evaluating biochars for their persistence in soil under field conditions is an important step towards implementation carbon sequestration. Current evaluations might be biased because the vast majority of studies are short-term laboratory incubations produced laboratory-scale pyrolyzers. Here our objective was to investigate stability a biochar with medium-scale pyrolyzer, first through characterization and tests then experiment. We also aimed at relating properties this that laboratory-made...
Biogas digestate is a nitrogen (N) rich waste product that has potential for application to soil as fertilizer. Composting of recognized an effective step reduce potentially negative consequences soils. However, the structure and high N content can hinder composting. Biochar, which be produced through pyrolysis biomass, shown improve compost increase retention in We studied how high-temperature wood biochar affects composting process, including greenhouse gas emissions, fertilizer value...
Abstract Carbon content is a key property of soils with importance for all ecosystem functions. Measures to increase soil carbon storage are suggested the aim compensate agricultural emissions. In Norway, where have relatively high because cold climate, adapting management practices that prevent loss atmosphere in response climate change also important. This work presents an overview potential sequestration Norway from wide range and provides recommendations based on certainty reported...
Iron is an essential nutrient. Its deficiency hinders the synthesis of ATP and DNA. We report that galactose metabolism defective when iron availability restricted. Our data support this connection because 1) galactose-mediated induction GAL promoter-dependent gene expression was diminished by limitation, 2) iron-deficient mutants grew slowly on galactose-containing medium. These two defects were immediately corrected replacement. Inherited in human are characteristic disease called...
A well-defined methodology for constructing appropriate atomistic representations of biochar will aid in visualizing the structural features and elucidating behavior with molecular dynamics (MD) simulations. Such knowledge facilitate engineering biochars tailored to specific applications. To achieve this goal, we adapted modeling strategies applied coal science by employing multi-cross-polarization 13C nuclear magnetic resonance, ultimate analysis, Fourier-transform infrared spectroscopy,...
