WebApr 11, 2013 · For three other soils (acidic and neutral clay loams and silty clay with variable cation exchange capacity, CEC), no significant effects on maize yields were observed (p > 0.2). In laboratory trials, 5% of the two biochars were added to the soil samples in order to study the effect of the biochar on physical and chemical soil characteristics. WebNov 15, 2024 · Biochar, produced through pyrolysis of organic matter, is negatively charged, thus contributing to electrostatic adsorption of cations. However, due to … WebThe most important measures of biochar quality include adsorption, cation exchange capacity, mobile matter (tars, resins, and other short-lived compounds) and type of organic matter feedstock used. Over time, adsorption ca-pacity of biochar decreases, whereas its cation exchange capacity increases (Cheng et al. 2008, McLaughlin et al. 2009). highlight cell range based on value
