Calibration of pesticide leaching models

Dubus, Igor G. (2002-09)

Complex deterministic models are being used within the context of pesticide registration to assess the potential for crop protection products to impact on the environment. Although calibration is in many ways at the heart ...
Evaluation of probabilistic modelling approaches against data on leaching of isoproturon through undisturbed lysimeters

Beulke, Sabine; Brown, Colin D.; Dubus, Igor G.; Fryer, Christopher J.; Walker, Allan (Elsevier, 2004-11-15)

This study evaluated probabilistic modelling approaches against data on leaching of isoproturon through two contrasting soil types. Leaching through undisturbed lysimeters from a sandy loam (Wick series) and a moderately ...
Using a linked soil model emulator and unsaturated zone leaching model to account for preferential flow when assessing the spatially distributed risk of pesticide leaching to groundwater in England and Wales

Holman, Ian P.; Dubus, Igor G.; Hollis, J. M.; Brown, Colin D. (Elsevier Science B.V., Amsterdam., 2004-01-05)

Although macropore flow is recognized as an important process for the transport of pesticides through a wide range of soils, none of the existing spatially distributed methods for assessing the risk of pesticide leaching ...
