ABSTRACT

The aim of this paper is to develop the simple imitation-optimization mathematical models for substantiating the drainage-irrigation systems on the basis of predicting the optimal soil water-salt regimes considering the water-air and thermal conditions of growing plants. This estimation is made by forecasting the water balance components in the root layer. Their values are determined by mathematical modeling of the moisture and salt transfer in the layer of active water-salt exchange (aeration zone), that is caused by natural and irrigation water.
