CHAPTER 6: Irrigation scheduling
CHAPTER 6: Irrigation schedulingIrrigation scheduling is one of the factors that influence the agronomicand economic viability of small farms. It is important for both watersavings and improved crop yields. The Irrigation water is applied to thecultivation according to predetermined schedules based upon themonitoring of: the soil water status; the crop water type of soil and climatic conditions have a significant effect onthe main practical aspects of Irrigation , which are the determination ofhow much water should be applied and when it should be applied to agiven addition to the basic factors relevant to the preparation of irrigationschedules examined below, other important elements should also beconsidered, such as crop tolerance and sensitivity to water deficit atvarious growth stages, and optimum water RELATIONSHIPT able presents a summary table of soil physical Irrigation TechniquesPressurized Irrigation of soil
Irrigation takes place when the permissible percentage (p) of available water (Sa) is depleted from the root depth, i.e. to replenish the depleted water. Therefore: Net depth of irrigation dose (d) (mm) = (Sa × p) D where Sa is the available water in millimetres per metre, p is the permissible depletion (fraction), and D is the root depth (m ...
