Repeated measurements
(2 weekly/ monthly):
- Soil moisture with permanent installed time domain reflectometers TDR (Campbell Scientific, type CS615) (10 cm and 40 cm depth) measured for each treatment every day.
- Soil temperature at 10 cm depth measured every one hour.
- Sediment loss every rainfall event.
- Surface water runoff every 5 minutes.
- Soil organic matter once for the whole period
- Soil strength of moist soil (shear vane, in kPa)
- Surface roughness (max difference microrelief in cm)
- Steady state infiltration rate, using an Eijkelkamp - soil air permeameter.
- Empty sediment tanks after each rainfall. Runoff is automatically recorded.
