Hi, I’m relatively new to KNF but an experienced irrigation director with vineyard management experience. Typical application rate for FPJ is 1:1000 and I also plan to inject it this year. Simple math: if you set the dosatron to 1% and dilute your juice 1:10 you have a 1:1000 right there. Total application rate per acre I don’t know, I would like to know that myself. But assuming your full watering rate is 5 gal per plant per week, that’s 2500 gal water per acre for your 500 plants. So 2.5 gal FPJ diluted in 25 gal water ( probably in a 30 gal barrel right?) would dose your entire watering. Keep in mind that if the dosatron is mixing into a 2 inch main it’s actually being diluted more than the reading on the dosatron says. But sending 2.5 gal per acre may be your answer. Good luck! I plan to apply about the same to other crops: if my full rate is 3000 gal per acre I would apply 3 gal FPJ once per week. Anyone else care to weigh in on using FPJ at scale?
