Abstract

A solution is given to the problem of heat conductivity in soil with heat conductivity and heat capacity varying in depth and heat conductivity coefficient varying periodically in time. Distributions of soil- and air temperature and moisture were found, as well as turbulent heat and moisture flows and heat flow into soil with boundary conditions of I and 2 kind stipulated at the interface of media, the original differential equations for heat and moisture conductivity containing internal sources of heat and moisture which simulate the presence and dynamics of growth of vegetation.
