I bought 1kg of FeSO4-based fertilizer. the label says "FeSO4x7H2O 90%" and it looks like green fine powder with
brownish-ochra globules, I suppose the remaining 10% fertilizing compounds. How can I separate the two? If I make it crystallize, will the fertilizing
stuff be excluded from the crystals? Is there another way?

Sieve it, if the FeSO4 is finer than the globules, that should make it very easy. You should stop recrystallize afterwards if you want a pure product.
