Hello,

Does anyone have an info on a bioavailability of urea to aquatic plants? I tried dosing 1 ppm of it twice - and didn't notice any NH3 concentration changes, so the hydrolysis should be very slow. Then I read on the Research Gate that it wouldn't decompose to release ammonia at an appreciable rate unless urease is introduced. Is there any evidence of aquatic plants having this enzyme?
