Varemurru is located on the coastal area of Gulf of Livonia and soils have been affected by the closeness of the sea and the vegetation (plants). The aim of our study was to investigate soils around Varemurru, Pärnumaa and compare thes to the soil map of Estonian Land Board..
We asked three research questions:
● Is it possible to predict from places with different vegetation that soils will be different?
● How does flora affect the amount of soil?
● How does the soil affect vegetation?
We made 3 excavations and collected samples from them. We analyzed the samples, identified the MUC core for eacg site. Based on the results we made a conclusion that soil does affect vegetation. Soils differ a little from the soil map data.
