Effects of Environmental Conditions on Rice-straw Biochar Adsorption of Nitrate

“…The biochar production rate decreased from 33.85% to 24.67% with the rise of temperature because of the greater loss of volatile constituents at the higher pyrolysis temperature [11]. As a result of the loss, positive correlation between BET surface area and pyrolysis temperature was discovered in the study, consistent with previous research [12,13,14]. The analysis of element revealed that carbon and oxygen were the dominate elements in biochars, 46.9%-53.3% and 12.9%-21.0%, respectively.…”

Balanced mixture of biochar and synthetic fertilizer increases seedling quality of Acacia mangium

“…Organic residues produce biochar with basic pH through heating by pyrolysis, due to the removal of functional groups that can generate acidity and the increase in ashes that lead to increased salts content (e.g., Ahmad et al 2013;Cantrell and Martin, 2012;de Moraes Goncalves et al, 2004;Dionisio et al, 2019;ISTA, 2013;Kratz et al, 2012;Marschner et al, 2012;Li et al 2011). The nutrients contained in salts such as KOH, NaOH, MgCO 3 and CaCO 3 , can be separated from the biochar matrix, causing an increase in pH and increasing the availability of these elements to be adsorbed by plants (Cao and Harris, 2010).…”
