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.
