Soil solution distillation by temperature and the possibility of vapour use by plants

Abstract

Thermogradient water transfer in soils is a global phenomenon and is associated with the rhythm of solar heat reaching the Earth. The article describes the mechanism of vapour-liquid thermogradient of water transfer. The effect of straight vapour movement in the pore space in the direction of heat flow is revealed. This phenomenon results in condensation of soil solution distillate on  plant roots. The dependence of soil water thermogradient transfer on temperature and the pore space size as well as on soil humidity and salinity was found. The great importance of the thermogradient vapour transfer in water supply for plants is noted.
