I use dolomitic limestone dust ( magnesium carbonate), but yes.

Reticulate Iris require the opposite of the conditions needed for
Hippeastrum. They like low humidity, cold, wet roots in winter,(not
waterlogged), and cold draughts. Sand, stone, clay, gravel or compost are
good for growing them in, so long as there is air and food in it, and it so
long as they do not dry out during their Winter growth. I suggest
temperatures of 4C (39F) to 12C (56F)  for their spring  Spring growth.
