Soil Decompaction By Frost Action

The article reports individual research technique and frost action of soil samples results findings that have been got to determine the effect of frost action on soil decompaction. The optimum values of the factors influencing decompaction process efficiency of compacted soil have been established. A nomogram was made up to determine the soil productive capacity after decompaction by frost action. The nomogram allows forecasting the future yield according to the guttation rate of test crops, depending on the initial soil bulk density and moisture content in autumn-winter period.
