1. Greenhouse & Nursery Irrigation

2. Greenhouse Irrigation Woodburn Area nurseries use 4 basic types of greenhouse irrigation systems – Solid-set Sprinklers – Overhead Spray Emitters – Mist Systems – Boom Spray

3. Greenhouse Irrigation Solid-set Sprinklers – Used for large volumes of water – Suitable for established plants that can tolerate overhead watering with large droplets

4. Greenhouse Irrigation Solid-set Sprinklers – Primarily used for containerized plants 4” and larger – Plants with large leaves or canopies can block water

5. Greenhouse Irrigation Microspray Emitters – Great for sensitive plants – Allows for precise watering

6. Greenhouse Irrigation Microspray Emitters – Efficient & accurate – Reduces waste – Minimizes weed germination

7. Greenhouse Irrigation Mist Systems – Used mostly for cutting & seed propagation – High humidity – Frequent, short waterings

8. Greenhouse Irrigation Boom Spray Systems – Large volumes of gentle spray – Precise delivery – Often used on cuttings and annual production

9. Greenhouse Irrigation Boom Spray Sprinklers

10. Greenhouse Irrigation Controllers – Allow growers to schedule irrigation – New technology ties controllers to computers and smartphones

11. 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

12. Nursery Irrigation Most is done by overhead impact sprinklers Some microspray is used on sensitive plants or large-canopied trees

13. Nursery Irrigation

14. Large holding ponds are created to reduce the demand on groundwater

15. Nursery & Greenhouse Irrigation Many similarities in equipment exist However, both are managed quite differently based on the needs of the plants & industry
