Requesting Help With Fertilizer Calculation


Junior Poster
Feb 12, 2017
Hi, I recently bought a dry fertilizer with following composition:

Fe 4.250%
Mn 3.200%
Zn 4.250%
Mg 1.280%
Cu 0.604%
Mo 0.059%
B 1.620%

Is it possible to use this for E.I dosing? I couldn't calculate how much I should use to make, let’s say 250 cc of liquid micro fertilizer. The problem is that Zn and Cu are almost 10 and 6 times more than CSM+B .

Second question important question is, what happens if I overdose of Zn and Cu ?

I appreciate any help with this problem.
