Water movement in a structured soil in the south-east of Ireland : preliminary evidence for preferential flow

Auteur :
RYAN, M.

Description :
A study was carried out on a structured soil in the south-east of Ireland to investigate flow patterns of water in soil. The results provided preliminary evidence for preferential flow in the soil. Nitrate leaching data, from a grazing study, tended to confirm the results. The importance of preferential flow with regard to movement of manures and chemicals towards groundwater, which will depend on the timing of the application of those substances and the occurrence of significant rainfall events is discussed. Soils having physical characteristics conducive to preferential flow are illustrated.
