Effect of the Colloidal and Chemical Nature of Humus on the Intensity of Ice Separation in Soil
The quicksand state of the Northern soils in thawed form, and the high ice content of certain levels of them in frozen condition is associated to a significant extent with the hydrophilic nature of the humus of these soils. In a survey of the seasonal freezing of the soils by zones, one can in no ev...

Summary: | The quicksand state of the Northern soils in thawed form, and the high ice content of certain levels of them in frozen condition is associated to a significant extent with the hydrophilic nature of the humus of these soils. In a survey of the seasonal freezing of the soils by zones, one can in no event overlook also the zonality of their ice state, depending to a known extent on the colloidal chemical nature of the humus of the given soils.
