Web1 de set. de 2013 · The Water Drop Penetration Time test (WDPT) ( Letey, 1969) was used to determine water repellency. The test consists of placing 10 water drops on the sample surface and measuring the time taken to infiltrate completely. Five air-dried sub-samples from each site were analysed using this method.
WebAccording to mainly USA-based laboratory studies, repellency is eliminated at a maximum soil temperature ( T) of 280–400°C. Knowledge of T reached during a wildfire is important in evaluating post-fire soil physical properties, fertility and seedbed status.
