摘要: Biochar, the solid residual remaining after thermochemical transformation of biomass for carbon sequestration, has been proposed to be used as a soil amendment, because its agronomic benefits. The effect amending with six biochars made from different feedstocks on sorption and leaching fluometuron 4-chloro-2-methylphenoxyacetic acid (MCPA) was compared other sorbents: an activated carbon, Ca-rich Arizona montmorillonite modified hexadecyltrimethylammonium organic cation (SA-HDTMA), agricultural residue olive oil production (OOW). Soil amended at 2% (w/w), studies were performed following batch equilibration procedure. Sorption both herbicides increased in all soils, but decreased biochar produced macadamia nut shells fast pyrolysis. Lower observed soils higher surface areas BC5 BC6 organoclay (OCl)....
