Sorption of s-triazine herbicides in organic matter Amended soils: fresh and incubated systems

摘要

Fresh amendment of soil with sewage sludge and composted sewage sludge resulted in increased sorption of three s-triazine herbicides: atrazine. Ametryn and terbuthylazine. The extent of increased sorption (as evaluated by sorptio coefficients K_d or K_f) was a function of soil type, such that sorption in amended organic carbon-poor soil (0.4 /100 OC) was more enhanced that in amended organic carbon-rich soil (1.55 /100 OC).
