    • Biochar is provided that is treated to have certain chemical and physical properties found to have the highest impact on plant growth and/or soil health. In particular, the following physical and/or chemical properties, among others, of a biochar have been identified as critical properties to control for in the selection of biomass feedstock, pyrolysis conditions, and/or enhancing treatment to increase biochar performance: (i) bulk density (ii) impregnation capacity; (iii) particle size distribution; (iv) solid particle density; (v) surface area; (vi) porosity; (vii) total porosity; (viii) ratio of macroporosity to total porosity (ix) content of residual organic compounds; (x) content of volatile organic compounds; (xii) ash content; (xiii) water holding capacity; (xiv) water retention capabilities; (xv) levels of dioxins and other potentially hazardous byproducts of pyrolysis; and (xvi) pH. Treatment can modify and preferably increase hydrophilicity/decrease hydrophobicity, remove dioxins from the raw biochar, modify electrical conductivity and/or surface charge, modify cation exchange capacity and modify anion exchange capacity, among other things.
    • Biochar被提供被发现具有一定的化学和物理性质被发现对植物生长和/或土壤健康有最高的影响。 特别地,生物炭的以下物理和/或化学性质已经被确定为控制生物质原料选择,热解条件和/或增强处理以提高生物炭性能的关键性质:(i) 堆积密度(ii)浸渍能力; (iii)粒度分布; (iv)固体颗粒密度; (v)表面积; (vi)孔隙度; (vii)总孔隙率; (viii)大孔隙率与残余有机化合物总孔隙率(ix)的比值; (x)挥发性有机化合物含量; (xii)灰分含量; (十三)持水量; (xiv)保水能力; (xv)二恶英和其他潜在危险的热解副产物的水平; 和(xvi)pH。 处理可以改变并优选增加亲水性/降低疏水性,从原始生物炭中除去二恶英,改善导电性和/或表面电荷,改善阳离子交换能力和改变阴离子交换能力等。
