(4661) Furrow irrigation
A method of surface irrigation commonly used in row crops. The furrows are channels formed between crop rows, typically a fraction of a meter wide and deep. The crop rows are ideally parallel to the direction of maximum field slope. During an irrigation, furrows are supplied with individual streams of water from a field ditch or gated pipe at the upslope end of the field. Infiltration occurs during the water’s advance, soaking, and recession phases. The water supply may be ‘cut-back’ after advance, to reduce runoff from the field.
