Transport of Atrazine Through Large Constructed Soil Columns With and Without Switchgrass Roots
In Tsegaye, Johnson, & Tsegaye’s study Transport of Atrazine Through Large Constructed Soil Columns With and Without Switchgrass Roots, listed in the conference proceeding abstracts, the effects of switchgrass (Panicum virgatum [used in the NYU NoPark garden]) roots on the transport of atrazine under continual porewater velocity are evaluated. Emporia and Cullen soil with no history of pesticide use were planted with 12 columns (6 Emporia, 6 Cullen) of warm season switchgrass and six other soil columns were left unplanted. Switchgrass roots had early breakthrough and long tails in the effulent curve for bromide and atrazine, suggesting the presence of nonequilibrium behavior and sorption. Switchgrass may increase groundwater pollution.
