Conteúdo:

(1) Measurements were made of water infiltration, water retention and porosity of soils of burned and unburned plots of heathland.
(2) On the burned plot the rate of infiltration was decreased by up to 74% compared to the unburned plot.
(3) Moisture retention in the top soil of the burned plot was increased considerably compared to the unburned plot.
(4) Mercury intrusion porosimetry (MIP) was used to investigate the porosity of the surface layers of soil following burning of the vegetation. an explanation of the results, based on the incorporation of ash particles, accords with the observed effects upon water infilatration and retention.
