February 27 | Injector Adjustment | Speaker: Jonathan Ebba

Fertilizer injectors are widespread in the greenhouse industry, but how many of us are using them for greatest profitability (and sustainability)?  Improper injection can result in wasted fertilizer, poor crop quality, inaccurate timing, root/ foliar disease and even increased pest pressure.  This presentation will show us how to simply monitor and calibrate our injectors as well as adjust them “on the fly” during the growing season.  We will also look at a free phone app from UNH Extension that does the math for us!

If you have questions or would like assistance registering for or accessing the webinars, including language access, please contact Jonathan at or (603) 749-2529.
