Abstract

An experimental computational method is proposed for determining the irrigation regime of agricultural crops and losses of irrigation water by infiltration beyond the root zone of the soil, based on information on soil moisture suction or soil wetness. It was established that under furrow irrigation the soil immediately below furrows is wetted approximately to maximum moisture capacity, while in the furrow spacing the moisture content of the soil usually does not exceed field capacity. A relationship is proposed approximating the curve of soil water intake. Results of calculations of the irrigation regime of cotton by the proposed method showed that the irrigation rate and the rate of infiltration of irrigation water decrease as the soils become finer in texture and the water table rises
