ABSTRACT
Finnish soil temperature regimes have been pergelic, cryic, and frigid, where pergelic is coldest and unsuitable for agricultural use. The study monitored soil temperatures at a soil depth of 50 cm in 2010, 2013, 2016 and 2019 to look at how the soil temperature regimes have changed. Probably, as a result of climate warming the soil temperature regimes in Southern Finland in the Helsinki region at a latitude of 60–61°N have raised from cryic and pergelic to warmer mesic over a period of ten years.
Key words: soil temperature regimes, climate warming, temperature zones, Baltic countries.
