In this paper, the authors treat the impact of peat amendment on sorption and leaching of fungicides penconazole and flusilazole
in two Algerian topsoil samples (Misserghine and Es-Senia). 1e batch equilibration technique was applied for adsorption
experiments, and leaching was tested through soil column simulated experiments under laboratory conditions. Adsorption data
fitted well to the Freundlich and linear models, showing the higher adsorption capacity of the Es-Senia soil for both fungicides, the
order of sorption being flusilazole > penconazole. Organic amendments increased the adsorption of both fungicides especially for
the soil with the lower organic matter (OM) content, obtaining a good correlation of this parameter with Kf, thus implying that
OM is the principal soil parameter governing fungicides adsorption. Results of soil column experiments indicated that peat
amendment decreased leaching of both pesticides in the soils studied. So, the use of organic addition migh...
