Yes, it is safe. There is no known chemical conflict between Sulfur and Urea, and neither makes the other less effective.
Which goes first, Sulfur or Urea?
Apply Sulfur first, then Urea. The general rule is thinnest to thickest texture, and lowest pH first.
Should I use Sulfur in the morning or at night?
