Abstract Various studies have established that feedstock choice, pyrolysis temperature, and type influence final biochar physicochemical characteristics. However, overarching analyses of pre-biochar creation choices correlations to characteristics are severely lacking. Thus, the objective this work was help researchers, biochar-stakeholders, practitioners make more well-informed in terms how these three major parameters product. Utilizing approximately 5400 peer-reviewed journal articles...
Amending soil with biochar (pyrolized biomass) is suggested as a globally applicable approach to address climate change and degradation by carbon sequestration, reducing soil-borne greenhouse-gas emissions increasing nutrient retention. Biochar was shown promote plant growth, especially when combined nutrient-rich organic matter, e.g., co-composted biochar. Plant growth promotion explained slow release of nutrients, although mechanistic understanding storage in missing. Here we identify...
Abstract Soil amendment with pyrogenic carbon (biochar) is discussed as strategy to improve soil fertility enable economic plus environmental benefits. In temperate soils, however, the use of pure biochar mostly has moderately-negative -positive yield effects. Here we demonstrate that co-composting considerably promoted biochars’ positive effects, largely by nitrate (nutrient) capture and delivery. a full-factorial growth study Chenopodium quinoa , biomass increased up 305% in sandy-poor...
With a growing world population and global warming, we are challenged to increase food production while reducing greenhouse gas (GHG) emissions. We studied the effects of biochar (BC) hydrochar (HC) produced via pyrolysis or hydrothermal carbonization, respectively, on GHG fluxes in three laboratory incubation studies. In first experiment, ryegrass was grown sandy loam mixed with equal amounts nitrogen-rich peanut hull BC, compost, BC+compost, double no addition (control); wetting-drying...
Land-management options for greenhouse gas removal (GGR) include afforestation or reforestation (AR), wetland restoration, soil carbon sequestration (SCS), biochar, terrestrial enhanced weathering (TEW), and bioenergy with capture storage (BECCS). We assess the opportunities risks associated these through lens of their potential impacts on ecosystem services (Nature's Contributions to People; NCPs) United Nations Sustainable Development Goals (SDGs). find that all land-based GGR contribute...
Agriculture and land use change has significantly increased atmospheric emissions of the non-CO2 green-house gases (GHG) nitrous oxide (N2O) methane (CH4). Since human nutritional bioenergy needs continue to increase, at a shrinking global area for production, novel management strategies are required that reduce GHG footprint per unit yield. Here we review potential biochar N2O CH4 from agricultural practices including mechanisms behind observed effects. Furthermore, investigate alternative...
Biochar, that is, carbonized biomass similar to charcoal, has been used in acute medical treatment of animals for many centuries. Since 2010, livestock farmers increasingly use biochar as a regular feed supplement improve animal health, increase nutrient intake efficiency and thus productivity. As gets enriched with nitrogen-rich organic compounds during the digestion process, excreted biochar-manure becomes more valuable fertilizer causing lower losses greenhouse gas emissions storage soil...
A widely abundant and invasive forest shrub, Eupatorium adenophorum, was pyrolyzed in a cost-efficient flame curtain kiln to produce biochar. The resulting biochar fulfilled all the requirements for premium quality, according European Biochar Certificate. either applied alone or mixed with fresh cow urine (1:1 volume) test its capacity serve as slow release fertilizer pumpkin field trial Nepal. Treatments included cow-manure compost combined (i) urine-only; (ii) biochar-only (iii)...
Slow release of nitrate by charred organic matter used as a soil amendment (i.e. biochar) was recently suggested potential mechanism nutrient delivery to plants which may explain some agronomic benefits biochar. So far, isolated soil-aged and composted biochar particles were shown considerable amounts only in extended (>1 h) extractions ("slow release"). In this study, we quantified ammonium biochar-amended compost during up 167 h repeated six consecutive steps determine the effect on...
Biochar derived from pyrolysis has received much attention recently as a soil additive to sequester carbon and increase fertility. Hydrochar, brown, coal-like substance produced via hydrothermal carbonization, also been suggested beneficial additive. However, before application, both types of char need be tested for potential toxic effects. The aim this study was develop simple, inexpensive, easy-to-apply test procedures identify negative effects chars but not provide false-negative results....
