Interesting questions, which I think are relevant for all soil solution experts. I could share my personal experience in Flanders (sandy - sandy loam soils), but I am not sure whether there is a general rule of thumb.
With regard to…"
in Flanders soil solution sampling was not affected by the corona measures so far. There was a slight delay in the analysis of samples during the second half of March, but as far as I know samples are analysed as planned since then.…"
Finally I can answer that I will attend the Joint EP Meeting. It sounds perfect to start a discussion on dry deposition, and creating a working group sounds even better.
I'll be glad to present our research on an empirical approximation to deposition velocities, as well as other techniques. I wish our colleagues join us in a discussion about the current and the possible methodologies in the Manual for dry deposition.
