Soils play a vital role in our global ecosystems. Soils affect the quality of our everyday life in
more ways than we understand, and we should put much more emphasis on it. We can gather
soil information from different geographic information systems, soil maps and handbooks.
Still, the best way to acquire knowledge is to go outside and collect the data yourself. The
fieldwork for this report was conducted during the GLOBE Regional Learning Expedition in
2022 at Käsmu, Estonia. To test the hypotheses of our work, we performed two soil
excavations following GLOBE soil protocols. As a result, we characterised different soil
types and confirmed our hypotheses. We found out that the soil and the vegetation on top of it
are strongly correlated because changes in the vegetation indicated a change in the soil type.
Finally, the grain size analysis confirmed that the grain sizes of the soil horizons differ from
the entire soil sample.
