Abstract Biochar is the porous, carbonaceous material produced by thermochemical treatment of organic materials in an oxygen‐limited environment. In general, most biochar can be considered resistant to chemical and biological decomposition, therefore suitable for carbon (C) sequestration. However, assess C sequestration potential different types biochar, a reliable determination their stability needed. Several techniques assessing have been proposed, e.g. proximate analysis, oxygen (O):...
Fractions of soil organic matter (SOM) were obtained from three soils using alternative physical fractionation procedures, and evaluated against the requirements model pools. We compared two‐stage density (isolating free intra‐aggregate fractions, before after dispersion, respectively) with particle‐size separation dispersed soil. For full comparison, organomineral fraction residual was also size separated. In standardizing density‐based method, we found recovery highly sensitive to as free....
Biochar—a material related to charcoal—has the potential benefit farming as well mitigate climate change.
Summary Roots are the first point of contact between biochar particles and growing plants, yet detailed studies biochar–root interactions few. Biochar may affect root growth, therefore plant performance, through two mechanisms: (i) as a direct nutrient source (ii) impacts on availability. To test hypothesis that occur determined by supply soil nutrients, spring barley ( Hordeum vulgare L .) was grown with without addition in rhizobox mesocosms. from unaltered artificially weathered...
The effect of rice-husk char (potentially biochar) application on the growth transplanted lettuce (Lactuca sativa) and Chinese cabbage (Brassica chinensis) was assessed in a pot experiment over three crop (lettuce-cabbage-lettuce) cycle Cambodia. biochar by-product gasification unit consisted 28.7% carbon (C) by mass. Biochar rates to potting medium 25, 50 150 g kg−1 were used with without locally available fertilizers (a mixture compost, liquid compost lake sediment). slightly alkaline (pH...
Abstract Biochar application to soil is currently widely advocated for a variety of reasons related sustainability. Typically, amelioration with biochar presented as multiple‐‘win’ strategy, although it also associated potential risks such environmental contamination. The most often claimed benefits (i.e. the ‘wins’) include (i) carbon sequestration; (ii) fertility enhancement; (iii) biofuel/bioenergy production; (iv) pollutant immobilization; and (v) waste disposal. However, vast majority...
Abstract Biochar is being actively explored as a tool for long‐term soil carbon sequestration. However, in order this to be effective the environmental stability of biochar must assured. Here, we define and test an accelerated ageing method that seeks reflect oxidative nature degradation soil. The was applied systematic set samples produced from sugarcane bagasse, four different biomass sources. these found range between 41.6% 76.1%, loosely correlating with O : C ratio ( r = 0.73)....
Abstract To assess the value of biochar to direct supply crop nutrients we considered release phosphorus, magnesium and potassium from a hardwood in sequential leaching experiment with deionized water. Cumulative P was proportionally large despite being quantitatively small, sixth extraction yielded 44–73% first, indicating that provision soil might be sustained for several seasons. Conversely, K but declined rapidly first last (6–18% extraction). Only 6–27% total Mg recovered. These results...
