Käsmu is located in Northern Estonia on the coast of the Gulf of Finland. The sea has
affected the vegetation and soil. The purpose of our research was to investigate different soils
around Käsmu village and control soil maps.
We posed 3 research questions:
● How do Käsmu's two soil types correspond to the map provided by the Estonian Land
Board.
● How do these two soil types correspond to landforms?
● How do these two soil types correspond to vegetation?
In addition, we established 3 hypotheses based on the previous ones:
● Soil types in nature correspond to the soil map.
● Soil types correspond to landforms.
● Soil types correspond to vegetation.
We did the fieldwork in one day on August 3, 2022.
The course of work was checking the study area from the soil map. To do this, we identified
two soil types on the map, searched for them according to surface pattern and vegetation
cover, collected the necessary data, dug two holes, described the soil horizons and collected
samples, analyzed the results and drew conclusions.
Based on the results, we concluded that the hypotheses are true.
