So we have a batch of fertilizer (liquid) that has been sitting around.  There have formed a lot of crystals, most likely potassium.  Any ideas on how to reverse this within the batch?  Will shaking help?  Could it be due to a chemical reaction?

List of ingredients: 

5% N
10% K2O
1.8% MgO
5.2% S
1% Fe
1.5% Mn
1% Zn

Thank you

Try shaking and gentle heating. These are not crystals of potassium. Potassium salt - perhaps.

[Goonie]

meaning that potassium fell out of the solution? 

[Borek]

That's what happens when you put potassium in water:

so what you have can't be pure potassium. It can be some potassium compound. Most likely some salt. But no guarantee solid you see contains potassium - it can be salt of any other metal present (or even of NH₄⁺).

Well the mixture is thick with medium viscocity.

We have a gyromixer that does a pretty good job of mixing but to no avail on being able to dissolve the crystals.


Would you recommend a sonic bath?  Or any other method?
