THE INFLUENCE OF FREEZING SOIL PROCESS ON ITS THINNING AND PRODUCTIVE ABILITY
The method of the laboratory-field research to determine the size of the soil thinning by freezing and express method which is based on the soil productive ability change are given in the article. The results of the research are given and it is established that for the effective process of decompression of the compressed soil by freezing it is necessary to use the optimal volume of dampness - not less than 28%. The nomogramm is done for the soil productive ability determination after thinning by freezing, which allows to forecast the future harvest by the intensity of guttation of the test-plant depending on the starting density and dampness of soil in autumn-winter period.
