Testing the ability to reduce the leaching of pesticides in soil amended with agro-industrial and composted waste

The retention potential of composted sewage sludge, orujillo (a solid residue from olive oil production), sawdust and sunflower seed shell to prevent soil leaching of atrazine, chlorfenvinphos, and chlorpyrifos was studied in open systems using fixed-bed adsorption columns. The columns were construc...
