eight infiltration models were investigated for their capability to describe water infiltration into soils. the models were; philip's, modified philip's, kostiakov's, talsma and parlange's, horton's, and lewis and milne's. field measurements of water infiltration were made using single ring infiltrometers on field plots established on a norwood soil (typic udifluvents) with four long-term (27 yr) winter cover crop treatments followed by cotton (gossypium hirsutum l. ) each year. based on r**2 values, horton, kostiakov and philip equations provided best predictions over all other models. soil bulk density and saturated hydraulic conductivity for two soil depths were not affected by the winter cover treatments.
