Hi

I am no expert on this but can think of a few safe measures which one can think of deploying:

1. Urine collected and diverted for irrigation should be diluted as much as possible ,with irrigation waters.

2.If not very expensive, try best to reduce the acidity of Urine collected to near neutral by adding Lime in small doses.

3. Let urine mixed irrigation water be utilised by crops/ trees where yield / fruit is not in direct contact with irrigation water (No creepers or Vegetables like cabbage/ Cauliflower/reddish/onion, potatoes, or lettuce, etc.

4. May pass collected Urine thru Charcoal filter if smell has to be reduced !
