Dissipation and loss of atrazine and metolachlor in surface and subsurface drain water : a case study / H.Y.F. Ng, J.D. Gaynor, C.S. Tan and C.F. Drury. : En13-5/94-64E-PDF

"This work evaluates the dissipation rates and losses of atrazine and metolachlor under controlled drainage/subirrigation and natural conditions. The evaluations are based on data measured in two field plots and an agricultural watershed with two different soil types, a poorly drained Brookston clay loam with low organic carbon fraction and a well drained Guelph loam with high organic carbon fraction. The dissipation rates and losses of atrazine and metolachlor are affected by organic carbon fractions of the soil types, but not by the magnitude of the spatial area. The field data presented in this report are useful for validation of pesticide transport models. The controlled drainage/subirrigation technology is a viable tool for minimizing the migration of agricultural pollutants into groundwater"--Management perspective.
