The root zone of the plant determines how big a soil reservoir there is for the plant from which to draw water. Early in the season the crops have shallow root zones that require light frequent irrigations. As the plant grows the roots go deeper into the soil with a corresponding increase in water requirements….
Design of the water delivery system will be based on water requirements of the field. Two factors must be known before design of the water delivery system can be done: system gallonage and system operating pressure.
The low energy precision application (LEPA) irrigation concept was developed primarily to allow irrigators in arid and semi-arid areas to maximize the use of their total water resource and significantly increase irrigation efficiencies.
