Dimy grass fertilizer - ammonium phosphate?

Put (A45)+(A47) = (A58), 300 g, in a 400 mL beaker with foam jacket,
in an ice bath. Started crystallizing between 25 and 21 C.

Washed (A53) (maybe deliquescing) with ethanol 92% (50 mL).  Dissolved completely.
Filtered with 28 µm paper:

* Liquid (A54) 38 g, clear.

* Solid (A55) practically nothing, discarded.

Tried to decant (A58) at 20 C. Failed: too many small ccrystals,
liquid would not come out. Reheated to 28 C.

Using 38 g (A54) to dissove/wash (A50) (72 g with beaker). Not evident if dissolved anything.
