The monthly monitoring period may be a bit too rigid, what about things that happen in between the monthly visit, eg a big storm, that might saturate the topsoil and reduce the moisture deficit? Should monitoring be more targetted? Perhaps to try to ‘capture’ an event, for instance the differential drying of sandy topsoils after a (presumably) heavy dew so that the (presumably) deeper colder soil retains its moisture and shows as a darker brown stripe in contrast to a paler brown stripe on shallower soil. I have been driving past this field for 7 years, at least 12 times a year and have only once seen the stripe pattern. I have had a similar experience with recording what must be medieaval ridge and furrow on the South Downs, I have seen the phenomenon only once in more than 20 visits over 20 years.
Hi Bob,
This issue has been troubling me, and some of the others, too. We are imposing a wholly artificial temporal framework that will not correspond directly to either environmental or land-management processes. The catch 22 is that we do not know what these processes are so we can not adequately pre-programme resources. The in-situ probes will be constantly logging temperature, soil moisture and soil density profiles so we will have some of these things covered. I would like to think that we will be able to respond by sending a team out to the sites for specific events (and in some instances will have to: crop marks, harrowing for example). I’m not sure how this might work for the ARSF hyperspectral surveys.
Thanks
Ant
