Urine: A Viable Agricultural Fertilizer?

And this is exactly what several progressive organizations have started to do. In Amsterdam, a company called Waternet held a demonstration in which men used public urinals to gather urine that later fertilized a rooftop garden. Also, Sustainable Organic Integrated Livelihoods, or SOIL, is a group that has installed numerous toilets in Haiti, a country that is severely lacking in sanitation. These toilets separate human waste in order to collect it, compost it, and later apply it for use in fertilizers.
Here in the U.S., the Rich Earth Institute employs similar, but more basic methods. The institute has received funding and grants from the USDA and EPA for their work in finding alternate solutions for farmers who cannot afford commercial fertilizers. In 2013, they received over 3,000 gallons of urine donations, and they expect that number to nearly double this year.
