Title: Fertlizer
Post by: johnm007 on May 29, 2021, 04:15:13 PM
Hello every one
Is it possible to mix the below given chemicals

1.MnSo4
2.MgSo4
3.KCL
4.K2So4
5.ZnSo4
6.Niso4
7.H3BO3
8.Na2MoO4
9.DTPA Fe 11%
10.CuSo4
In distled water to make liquid fertlizer
Without reacting with each other

Thank you in advance

No, because Na2MoO4 will cause precipitation of Mn, Zn, Ni, Fe and Cu molybdate salts.

Is there a where to mix them so they dont form precipitate ??
Like lowering ph etc ?

Na2MoO4 is mild oxidizer. At lower pH it will not react with Mn2+ (H2MoO4 + Mn2+ ---> 2 H+ + MoO2 + MnO2), also - will not oxidize water to O2 (H2MoO4 ----> MoO2 + 1/2 O2 + H2O), but this will not prevent formation of the precipitate.

What is needed is the reduction of Na2MoO4 to some soluble Mo3+ or Mo2+ salt (K4Mo2Cl8 is soluble but [Mo2Cl8]2- may still form precipitates with iron, copper etc.).

That would not help other forum members on this forum who are following this thread.
