This survey constitutes a continuation of corresponding surveys undertaken in Finnmark, Troms and Nordland Counties, as well as in North Trøndelag and on Fosen. During the main field work in 2018, and the complementary field work in 2019, organic soil samples (humus) and mineral soil samples were collected in a grid of 6x6 km in the remaining part of south Trøndelag. In total 454 locations where sampled. The <2 mm dried size fraction of these samples were analysed by ICPMS for 53 elements following Aqua Regia digestion. In addition, loss of ignition (LOI) is determined at 480\u00B0C. In this report quality of analytical results of organic soil are documented in tables, descriptive statistics and by single element maps on a backdrop of bedrock geology. A separate QC-report for the mineral soil samples has been published previously. 67165
