Reliable, high quality water is critical to fruit and vegetable production. The CFVGA Water Committee is therefore dually charged with (1) providing water resource information that can assist CFVGA members to continue and advance their farming operations and (2) connecting members, water policy makers and regulatory agencies to promote understanding of the potential impacts both positive and negative, of water related policies on our members.

General Water Resources
- Optimal irrigation efficiency yields best crop performance
- WISE is a web tool to help growers make irrigation scheduling decisions (when to irrigate? how many inches?)
- FC = field capacity, the maximum amount of water a soil can hold before gravity drains water down through the soil
- AWC = available water capacity, amount of water plant roots can get from the soil, less than FC
- PWP = permanent wilting point, the plant is dead!
- MAD = management allowable depletion, the amount of water that can be lost from the soil before plant yield is reduced, varies by crop and soil texture, DO NOT EXCEED MAD
- Drip irrigation is designed to apply relatively low volumes of water more efficiently than other irrigation systems.
- When not properly managed, any increase in irrigation efficiency provided by a drip system can be lost.
- Crops extract about 70% of plant available water from the upper half of their root system.
- Application efficiency of drip irrigation is approximately 90%.
- Learn simple calculations to determine how many minutes to irrigate with drip tape
