Abstract
The article presents some basic elements of soil frost and its occurrence. The data contains observations from different regions and soil types in Finland. Different forms of soil frost and factors affecting its formulation are discussed.
The article concludes with the factors effecting soil frost. There are three issues. By the single grain soils the water content determines whether the frost becomes massive or layered. The structure of soil determines the occurrence of hollow formed frost. Within the soils with crumb structure both layered and hollow formed frost may occur. Layered frost may occur in soils with homogeneous crumb structure in which two kinds of ice layers occur: irregular and solid. The hollow-formed frost may occur in locker soils.
