WebBiochar with a high cation-exchange capacity has a lower tendency to leach out the crucial plant nutrients from soils. The pyrolysis temperature has an inverse effect on the cation-exchange capacity. Cordgrass biochar produced at 200°C has a cation-exchange capacity of 44.5 cmolc/kg and then further reduced to 32.4 cmolc/kg at 550°C pyrolysis ...

WebDec 3, 2014 · Biochar refers to a carbon (C)-rich and porous substance, which is produced by thermal decomposition of biomass under oxygen-limited conditions and at relatively low temperatures (<700°C) [1]. It has a high specific surface area, a high density of negative surface charges, and characteristic pores and surface functional groups [2]. WebJul 13, 2024 · Especially, biochar enriched with carboxyl and phenolic C groups has a higher cation exchange capacity (CEC), thus presenting a higher capacity to adsorb nutrients . The properties of biochar are significantly dependent on the feedstock types and the pyrolysis conditions, as well as on pre- and post-pyrolysis treatments [ 9 , 18 ]. tax rate india
