A method of irrigating a field for maximum efficiency wherein the water is flowed onto the field from above and from mobile irrigation apparatus at a flow rate far exceeding the permeability factor of the soil. Slots are formed in the soil surface to receive the inherent water runoff to conduct the water into the subsurface soil regions. The water may be discharged directly into the slots by aligning hoses and the slots and the latter are preferably mulched to minimize evaporation. Elongated irrigation manifolds are moved through successive arcs swung about pivot points at alternate ends of the manifold to maximize length of crop rows and the efficiency of movement of the apparatus in the irrigation operation.
