Estimate gross vineyard irrigation volume from vine count, daily vine demand, planning days, effective rainfall, and system efficiency. Results distinguish water used by the crop from water that must be delivered and show the average daily volume and delivered water per vine for pump-capacity and allocation planning.
The main result is gross water that the irrigation system needs to deliver during the selected period.
Use local evapotranspiration, crop coefficient, soil moisture, rooting depth, phenological stage, and regulated-deficit strategy to set the daily vine demand.
For 3,000 vines at 2.5 gal/day over 21 days, with 10% effective-rainfall offset and 90% efficiency, net demand is 141,750 gal and gross delivery is 157,500 gal.
No. Reflect the chosen deficit strategy in the daily water need entered.
Use the number of productive vines actually receiving and using irrigation.
The system must deliver extra water to cover application losses.
Yes. Enter liters per vine per day and read all volume outputs as liters.
No. It is the fraction of crop demand actually met by stored, usable rainfall.
