To establish the optimal balance in «income-costs» during irrigation of agricultural crops, an algorithm has been developed for determining a techno-economically substantiated irrigation rate that ensures maximum profit, taking into account the cost of irrigation and the cost of crop increases from irrigation. A techno-economically sound irrigation regime allows planning and conducting irrigation at a rate that gives the maximum economic effect.
