Scientific basis for soil water and plant nutrients management is developed. New index and method for estimating the soil-crop water status as a whole for the growing season is used. Equations to calculate the N, P and K fertilizing rates, corresponding to specific soil-crop water status created, are offered. The application of the basis leads to improved water-fertilizers use efficiency, multi-variant management and provides new opportunities for both the investigators and the farmers.
