Modeling of water and salt transfer in the initial period of plant development

Abstract

Water - as moisture, has an essential role in all biochemical processes of plants; all vital processes occurring in a vegetative organism can proceed normally only under the condition of sufficient saturation of cages by moisture. Results of theoretical researches on dynamics of ground humidity have shown: (1) similarity of physical processes of change of humidity of soil on different irrigated areas (2) hysteresis of the nature of humidity at irrigation and drainage. (3) sharp recession of humidity of soil in the root zone.
