The soil nutrient alterations do not appear to affect tree growth in the short-term, as biochar had aneutral main effect on poplar growth. These results suggest that biochar produced frombioenergy production could be returned to forest soils to replenish soil nutrient stocks andenhance C storage,...
little is known regarding gas fluxes from forest soils in response to biochar additions. These fluxes are of interest as they help to determine the climatic effect of C management in forested ecosystems, where biochar
Biochar also promotes the production of ethylene (C2H4), which is the only hydrocarbon and an important plant hormone with a pronounced effect on plants (Spokas et al., 2010). The study further indicated that a greater ethylene production was obtained from non-sterile soil than sterile soil (...
Production of biochar (the carbon (C)-rich solid formed by pyrolysis of biomass) and its storage in soils have been suggested as a means of abating climate change by sequestering carbon, while simultaneously providing energy and increasing crop yields. S
We investigated the effect of maize residues and rice husk biochar on biomass production, fertiliser nitrogen recovery (FNR) and nitrous oxide (N2O) emissions for three different subtropical cropping soils. Maize residues at two rates (0 and 10 t ha−1) combined with three rates (0, 15 and...
15i–k). However, upon reaching x = 8, there was no noticeable alteration in the porosity and structure of HPC-UP-8 compared to HPC-UP-6, indicating that the activation effect of KHCO3 ceased to have a significant impact once x reached a value of 6. The microstructure of HPC-UP...

A long-term field experiment was established in 2009 so as to determine the effect of biochar on crop yield and soil properties in a calcareous soil. Five treatments were: 1) straw incorporation; 2) straw incorporation with inorganic fertilizer; 3), 4) and 5) straw incorporation with ...
Therefore, the CH4 production and consumption processes were influenced by different soil moisture levels and microbial communities of different soils. 展开 关键词: Biochar Methane emission Soil moisture Methane oxidation activity Priming effect DOI: 10.1007/s00374-012-0703-4 被引量: 119 ...
