| Zusammenfassung |
| Soil water repellency (SWR) alters the way water interacts with soil by impacting
hydrological and biogeochemical cycling to an extent which is not yet fully understood. Most
studies have focused on SWR in specific environments and habitats, mostly in Mediterranean
climates, but SWR has been increasingly observed in a range of habitats from the tropics to
the northern latitudes. To better assess the distribution of this phenomenon, we propose using
citizen science to create a means of crowd-sourcing SWR data from around the globe using
the mySoil app.
The water drop penetration time (WDPT) test, in which the length of time a drop of water
remains on the soil surface is measured and a corresponding qualitative water repellency
class is assigned to the soil, provides useful data and is easy to use. We propose
adding a simple, standardised WDPT protocol to the mySoil app and web portal so
both academics and non-scientists can contribute to the collection of SWR data
from around the world. The protocol would include guidelines on drop size and
the number of drops to apply, and would encourage inclusion of details such as
vegetation cover, soil moisture conditions, last rainfall, and broad habitat. By initially
engaging with researchers to create a back bone of respondents, we believe we can
develop a global assessment that will reveal the distribution of the SWR phenomenon. |
