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.
