Vineyard Irrigation Scheduling Worksheet (Interactive) This worksheet provides the means to calculate the amount of water to apply in a winegrape vineyard based on the deficit irrigation strategy fully detailed in the publication "Deficit Irrigation of Quality Winegrapes Using Micro-Irrigation Techn...
When to start irrigating Vine leaf water potential (LWP) is an indirect measure of vine water status that is usually monitored weekly prior to the onset of irrigation. LWP is most accurately measured with a pressure chamber device. Units of LWP are negative bars or megapascals (MPa).
Emitter Sampling for Distribution Uniformity DeterminationDrip emitters rarely discharge water at the exact specified rate or uniformly across the irrigation system. For example, a 0.5 gallon per hour (gph) dripper may not actually be discharging at 0.5 gph. Manufacturing differences, clogging, and…
How to Calculate Distribution Uniformity and Adjust Irrigation Requirements Emission uniformity is expressed as a percentage, and is a relative index of the variability between emitters in an irrigation block.
