Description/Abstract

A considerable proportion of the water from low and high intensity applications (2 and 108 mm dayt-1 falling on an unsaturated saline and sodic clay subsoil moved rapidly down through the soil profile via the macropores, and was capable of efficiently leaching salts from the unsaturated clay mass. The high efficiency of leaching indicates that saline sodic clay soils in temperate climates, such as those in the Hoo Marshes, might be more safely and more cost effectively drained by means of surface drainage systems rather than buried pipe drainage systems.
