In this study human urine was collected and stored in covered containers in the donors’ homes for two weeks in order to protect against pathogens. There is a wide range of opinions on how fresh the urine should be but allowing the urine to sit for a couple of weeks seems the safest of all of the approaches.

The final consideration – and it is an important one – is what volume of urine should be applied to the crops and how much should it be diluted? What is interesting about the Ugandan study is that they cited the urine application as direct and undiluted. Nearly every source out there will tell you that you need to dilute the urine with water at a 10:1 water to urine ratio. And that is what we have historically practiced in our own gardens and orchards.
