Sulfos brings sulphur and phosphorus together with urea at 8%. The combination is deliberate — rumen microbes need nitrogen and sulphur in a workable ratio, so adding urea without sulphur on sulphur-short country leaves the benefit on the table.
Urea safety — read before feeding
Urea is toxic if eaten too fast. Introduce urea blocks to stock that are full rather than hungry, never place them where an empty mob arrives first, keep water available at all times, and do not feed urea products to horses. Stock returning after a break from a urea block need re-introducing as though it were new.
Feeding & Use
