Greenhouse & Nursery Irrigation
Greenhouse Irrigation
• Woodburn Area nurseries use 4 basic types of greenhouse irrigation systems– Solid-set Sprinklers– Overhead Spray Emitters– Mist Systems– Boom Spray
Greenhouse Irrigation• Solid-set Sprinklers– Used for large volumes
of water– Suitable for established
plants that can tolerate overhead watering with large droplets
Greenhouse Irrigation• Solid-set Sprinklers– Primarily used for
containerized plants 4” and larger
– Plants with large leaves or canopies can block water
Greenhouse Irrigation• Microspray Emitters– Great for sensitive plants– Allows for precise
watering
Greenhouse Irrigation• Microspray Emitters– Efficient & accurate– Reduces waste – Minimizes weed
germination
Greenhouse Irrigation
• Mist Systems– Used mostly for cutting
& seed propagation– High humidity– Frequent, short
waterings
Greenhouse Irrigation
• Boom Spray Systems– Large
volumes of gentle spray
– Precise delivery
– Often used on cuttings and annual production

Greenhouse Irrigation
• Controllers– Allow growers to
schedule irrigation– New technology ties
controllers to computers and smartphones
Greenhouse & Nursery Irrigation
• Most groundwater needs amending before being used for irrigation– Sand filters take out salts
and other particulates– Fertilizer injectors allow
for even dosing with irrigation
Nursery Irrigation
• Most is done by overhead impact sprinklers
• Some microspray is used on sensitive plants or large-canopied trees
Nursery Irrigation
Nursery Irrigation
• Large holding ponds are created to reduce the demand on groundwater
Nursery & Greenhouse Irrigation
• Many similarities in equipment exist
• However, both are managed quite differently based on the needs of the plants & industry
