 So welcome to this webinar, this training session on the implementation of the glosolone SOP for electric, sorry, electric conductivity. Before starting the session, let me explain a little bit how the session will be structured. So I'm Filippo Benedetti. I'm working at the Global Soil Partnership of FAO where I'm supporting the activities of glosolone, the Soil Laboratory, Global Soil Laboratory Network, together with my colleague Luca Zecaon. I will give a short introduction to this, to the network and to this webinar. Then I will leave the floor to the guest speakers of today. Then after the presentation, after the presentation, you will have the opportunity to raise questions to them directly. So you can also write your question in the chat. But at the end of the presentation, there will be a question and answer session where you can interact directly with the speakers. So let me share my presentation just a second. I hope you can see my screen. As mentioned, I'm Filippo Benedetti, and this online training session will be on SOP for Soil Electrical Conductivity. This webinar has been organized by Glosolone. Glosolone is the Global Soil Laboratory Network, a network that was established in 2017, so five years ago, to improve, to strengthen the analytical capacity of soil laboratories and to harmonize protocols and standards across laboratories, countries and religions. The network has three main areas of work. The first one is the quality assurance and quality control, because it is very important that the data produced by laboratories, soil data are reliable. So this means accurate and precise and interpret and compare and comparable among different laboratories. To do so, we have to be sure that laboratories implement both internal and external quality control procedures. And so we are supporting them, preparing reference samples and also organizing proficiency tests, also called ring test or interlaboratory comparison. So basically we support countries and labs in organizing PT and we also organize a PT and the new PT actually will be a global PT will be launched in upcoming weeks, organized by Glosolone. We also work on SOPs, so we are monetized under rubric procedures, taking into account all the inputs received from the network members, and we facilitate the implementation of these SOPs, also through these kinds of webinars of today. So we organize, for instance, we are monetized SOP on analytical conductivity last year, and today's webinars is to the aims to facilitate the implementation of these SOPs. And also we work on equipment by giving training some equipment purchasing, use and maintenance, and by establishing a donation and bartending system. We also working on soil spectroscopy so the application of this cutting edge technology to soil analysis. And for this reason we launch an initiative on soil spectroscopy last year in 2020. And we also focus on fertilized analysis as this was identified as a main need for the.
