Abstract

Abstract

The purpose of this study was to investigate bromide and water distributions in soils as the result of macropore structure and sprinkling rate. Water was found to have moved laterally from the macropores into the soil matrix. It also has moved deeper into the soil with higher macroporosity and when applied at higher rates, as was indicated by bromide tracer profiles. Evidence is presented that the soil volume measured with a double tube gamma-ray probe was too small to follow the wetting process completely when macropores contributed to flow. A parameter, derived from the bromide profiles, can be used to characterize the hydraulic importance of macroporosity, based upon a simple approach to water flow along macropores.
