Sensitivity to erosion is hard to measure as absolute values can not be obtained. It is, however, possible to obtain a reasonable indication by means of a relative measurement. For such a measurement a rainfall simulator can be applied.
With the rainfall simulator, the runoff and soil loss generated by a standardised rain shower is measured on a plot with standard surface area. The duration, intensity and kinetic energy of the shower are such that a high sensitivity of the test results for differences in soil properties is obtained.
The extent to which the soil is sensitive to erosion is determined largely by the composition of the soil. Knowledge of the sensitivity to erosion is important for the development of a certain plot.
