   Im I good to mix 15.5-0-0 Calcinit with Ferrous sulfate? Looking to folier feed my burmuda for some color. Thinking of 2 bags (100lbs) Calcinit and 1 bag (50 lbs) Ferrous sulfate over 20 acres of fairways.
   
   Thanks,
   Dave

   Do a jar test first. I've heard stories where the calcium from the Cal nitrate reacts with the sulfate in the ferrous sulfate to form calcium sulfate (gypsum) in the spray tank. Could be a mess cleaning out your tank.

   That's a normal mix for us for greens in winter in Vegas. Never had any issues as long as kept agitated. 50 lbs CaNo3, 25 lbs FeSo4 for 2.7 ACs.
