<p>Dear Experts on Soil Solution,</p>
<p>I have a question regarding the life span of the tension lysimeters. In Switzerland, our lysimeters still run well; however, I wonder what the “normal” life span of those lysimeters is. For how long do you use your lysimeters and do you see signs of ageing?</p>

<p>Further, I wonder in case of renewal how long it takes for installation effects to flatten out. In Switzerland, the data analysed by Elisabeth showed that it is a good idea to remove the first year. Do you have any other experience?</p>
<p>Thanks for sharing your thoughts!</p>

<p>Dear Experts,</p>
<p>hoping you all are in good health and having enough patience while living trough these challenging times.</p>
<p>I am also wondering about the status of our soil solution survey. What kind of impacts the corona pandemic might have on collection and analysis of soil solution.</p>
<p>I would be pleased to get information on how Level II surveys, especially soil solution collection and analysis, are currently running in different countries.</p>

<p>Dear Experts on Soil Solution,</p>
<p>As the 19th EP meeting in Göttingen is approaching, I think it would be a good time to start to gather thoughts on subjects concerning soil solution collection and analysis. The EP meeting is a great opportunity to meet and discuss to all the experts, who are able to arrive to Göttingen. However, I think it would be extremely useful to change opinions and ideas even before the meeting. Especially since many of us will not be able to attend the meeting.</p>
<p>One important topic on the agenda is the feasibility of the current version (2011) of the soil solution manual. During the meeting we have scheduled one hour on Thursday morning, 23th April, to discuss how to proceed with update of the manual. Therefore, I am asking for your opinions concerning the need and urgency of soil solution manual updating.</p>
<p>There are two points which I would like to take under discussion. First, pooling of samples, it is an issue not recommended by the manual, but due to drastically decreased funding Finland was forced to start pooling samples of individual lysimeters since 2013 to get only one bulked sample for each depth at a plot. The numbering of these bulked samples was not straightforward. According to the manual new numbers have to be given to new samplers, but we did not do any changes to samplers. We only bulked the samples within one depth in the field by the time of sampling. In our opinion, the most reasonable way to proceed was to give new sampler ID:s to our groups of “old” samplers. I am eager to hear opinions on this. And should the manual give guidance to this kind of changes in the collection system? Other countries may have had or may face similar changes in the future.</p>
<p>As a second point, I would ask about the <span style="color: black; line-height: 115%; font-family: 'Verdana','sans-serif'; font-size: 10pt; mso-ansi-language: EN-US; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-US; mso-bidi-font-family: 'Times New Roman'; mso-bidi-language: AR-SA;" lang="EN-US" xml:lang="EN-US">acceptability of zero-tension lysimetry.</span> Spanish colleagues contacted me recently and asked about the “legality” of the use zero-tension lysimeters. According to the manual tension lysimeters are the standard method for ICP Forests soil solution collection. However, some countries (Finland included) have zero-tension lysimeters in use. I would like to take this issue under discussion as well. Are zero-tension lysimeters acceptable? As a sole method? Or only together with tension lysimeters?</p>
<p>What about other points? Have you noticed major or minor inconsistencies or something else which would need to be updated? Please, report your findings, even tiny mistakes need to corrected.</p>
<p>I am looking forward to an active discussion!</p>
<p> </p>
