Furrow irrigation. View across an early-growth cotton (Gossypium sp.) field watered by furrow irrigation. Furrow irrigation, using parallel water-filled channels (corrugations), is used when the crops can be planted in rows. The water level in the corrugations is maintained by siphons leading from the ditch at lower right. Photographed in Tulare, California, USA.
