What is irrigation scheduling and why is it important ?
Irrigation scheduling is a generic term for a number of techniques that aide the irrigator in determining when and how much to irrigate. When to irrigate is usually an agronomic question. That is, do you want to irrigate to avoid stress or, as is the common situation with a crop like wine grapes, irrigate to induce a certain amount of stress. How much to irrigate generally depends on the type of irrigation system. If it is a low-frequency flood-type system, furrows or border checks, “how much” to irrigate is generally the soil moisture deficit in the root zone plus any leaching fractions needed to maintain a salt balance. With high-frequency, micro-irrigation systems the “how much” is a calculation of required hours of operation based on the estimated crop water use.
