| Abstract/Contents: | "When convection-dispersion models are used to predict the transport of pesticides applied to turf, the presence of thatch is usually considered by averaging the organic carbon content of the thatch into the uppermost soil layer. An assumption made when using this approach is that thatch and soil have similar sorptive properties. A series of sorption and column transport studies were conducted to examine this assumption and to determine the impact of thatch on predicting pesticide leaching losses from turf. Sorption studies revealed that thatch organic carbon is a less effective sorbent for some pesticides than is soil organic carbon. This indicates that soil pesticide absorption values obtained by averaging the organic carbon of thatch and soil will usually overestimate pesticide retention in upper most soil layer when the values are derived using soil based normalized sorption coefficients. Column studies demonstrated that model predictions of pesticide transport in soils containing thatch are comparable to predictions of pesticide transport in soils devoid of thatch when model retardation factors are based on separately measured thatch and soil sorption coefficients." |
