Alachlor was broadcast onto plots as either an emulsifiable concentrate (EC) or a microencapsulated (ME) formulation. Terbufos was either banded over furrows or incorporated in-furrow as either a granular formulation (15G) or a controlled release formulation (20XL). Alachlor formulation did not affect dissolved alachlor losses, however, adsorbed and total ME alachlor losses were greater than adsorbed and total EC alachlor losses. Losses of dissolved, adsorbed, and total terbufos were greater from banded treatments than from in-furrow treatments. Adsorbed 20XL terbufos losses were frequently greater than adsorbed 15G losses, however, dissolved terbufos losses were not greatly influenced by terbufos formulation.","A computer model was developed to simulate the availability of pesticides in the soil matrix and uptake of these pesticides into overland flow. Pesticide Availability and Transfer Simulator, PATS, accounts for the distribution of chemical within soil, adsorption kinetics, and chemical release from soil to overland flow. PLIERS, Pesticide Losses In Erosion and Runoff Simulator, was used to simulate surface transport of pesticides. Hydrologic data required by PATS and PLIERS were generated by the distributed parameter hydrologic model ANSWERS.","PATS was incorporated into PLIERS creating PATS enhanced PLIERS. Performance of PATS enhanced PLIERS was evaluated by comparing model predictions to observed data. PATS enhanced PLIERS dissolved pesticide loss predictions were similar to predictions made with PLIERS without PATS enhancement and were in good agreement with observed data. PATS enhanced PLIERS adsorbed pesticide loss predictions were frequently lower than observed losses, but were generally closer to observed losses than were PLIERS adsorbed pesticide loss predictions.","Made available in DSpace on 2011-05-07T12:18:56Z (GMT).
