Human urine can help grow bumper tomato crops that can be eaten safely, says a new study.
Surendra Pradhan, an environmental biology researcher at the University of Kuopio, Finland, and colleagues gave potted tomato plants one of three treatments: mineral fertilizer, urine and wood ash, or urine only.
Yields for plants fertilized with urine, rich in nitrogen, phosphorus and potassium, quadrupled and matched those of mineral-fertilized plants. The urine-fertilized tomatoes also contained more protein and were safe for human consumption.
"This is a very simple technology. Urine can be collected in a urine-diverting toilet or it can be collected in a separate jerry can [from] an ordinary, pre-existing toilet," said Pradhan.
"If wood ash is available, this can be use as a supplement of phosphorus, potassium and other nutrients," Pradhan added.

At Artangardens in North Bay, Mr. Artan pees everywhere on the property. Nutrients in pee, especially the vast amount of vitamins in North American urine need to be used!

Be sure to dilute your pee (& ashes, if using them) first...

Now that's really interesting, and seems to be safer than reclaimed water, at least you know whats in it.
