Irrigation efficiency involves the ability to minimize water losses. Such factors as loss of water from wind drift and evaporation from the soil surface and plant affect the level of efficiency.
Irrigation technology
Chemicals through sprinklers
The concept of applying fertilizers, herbicides, fungicides and other chemicals via center Pivot irrigation systems is fast becoming a major cost reducing method.
Irrigation scheduling
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….
