How fast does urea hydrolize in solution with excess Ca(OH)2?

I have fertilizer that contains K, NH4, PO4 and urea.

Now as I already know the method, potassium nitrate can be made from any potassium salt and NH4NO3 during cooling as the solubility is greatly different.

But now I would like to cool the solution after addition of excess Ca(OH)2, but I don't want urea to interfere. How fast does urea hydrolize in alkaline Ca(OH)2 conditions? Calcium phosphate should also precipitate.
