SOME RESULTS OF FIELD OBSERVATIONS ON THE FROST PHENOMENON ON PEAT SOIL

FIELD OBSERVATIONS ON GROUND FROST CARRIED OUT DURING THE WINTER PERIOD 1953-1954 ON PEAT SOIL REVEALED THAT THE RELATIVE TOTAL WATER QUANTITY IN THE FROZEN ZONE FORMED DURING A PERIOD OF SLOW COOLING (IN PERCENT BY VOLUME) IS HIGHER THAN THAT RESULTING WHEN FREEZING TAKES PLACE AT A FAST RATE. WITH INCREASING FROST DEPTH, THE SOIL IMMEDIATELY UNDER THE FROZEN ZONE DRIED OUT TO SUCH AN EXTENT THAT THE MINIMUM VALUES OF ITS MOISTURE CONTENT WERE LOWER IN THE WINTER THAN IN THE SUMMER. THE TOTAL QUANTITY OF WATER STORED IN THE FROZEN ZONE EITHER IN FROZEN OR IN LIQUID CONDITION (IN PERCENT BY VOLUME) INCREASED CONTINUOUSLY IN THE COURSE OF THE WINTER WITH FURTHER INCREASE IN FROST DEPTH. AFTER THE INCREASE OF FROST DEPTH HAD CEASED, THE MOISTURE CONTENT OF THE SOIL LAYERS UNDER THE FROZEN ZONE ONCE MORE BEGAN TO INCREASE BEFORE THE START OF THE THAWING PERIOD. THE OBSERVATIONS SHOW THAT THE FROST PHENOMENON BOTH DEVELOPED AND ACTED ON THE MOISTURE CONDITIONS IN THE PEAT SOIL INVESTIGATED IN A MANNER LARGELY SIMILAR TO THAT WHICH IT IS KNOWN TO FOLLOW ON MINERAL SOILS. /AUTHOR/
