A Reminder about Fertilizer Injector Maintenance

Spring is here, and we know you’re busy!  Here’s a quick but very important refresher on fertilizer injector maintenance.  Ensure they’re working properly on a regular basis to avoid extra headaches.

How do I know if my injector is working properly?

Hopefully damage to foliage wasn’t your first sign things were a little off! Some things to remember:

  • The dilution ratio needed for each application should be known and adjusted as needed.
  • Remember that tracing dye in water-soluble fertilizers should never be used as an indicator of the actual strength of a fertilizer mixture.
  • If you are using multiple products or chemistries ensure they are compatible for tank mixing before running them through the injector.
  • If deviations greater than 5% from the expected setting occur, contact an irrigation specialist for assistance or repair. (But first, double check that math!)

Fertilizer injectors come in all shapes and sizes in the greenhouse.

There are two common methods to check if your injector is working as expected. Regular calibration is needed to ensure that an injector is operating properly. You should complete both methods listed here to ensure accuracy. Continue reading

Don’t have a facility-wide Pest Management Program in place?  This guide can provide the framework. (Why start from scratch?).  Already have a strategy to mitigate risks from pests at your farm?  Compare YOUR plan with the Floriculture Guide to see if you’ve overlooked anything.
