In a vain attempt at producing gold, 17th century alchemist Hennig Brand accidentally discovered elemental Phosphorus while heating within a glass retort the residues from boiled down urine. In modern times, this ‘liquid gold’ is seen as a valuable source of increasingly limited phosphorus and useful soluble nitrogen fertilizer. It’s application in the garden is profound, but it should not be used without careful consideration.

Join us for a continuation of our Waste Not series, where biochar facility manager Dan Hettinger takes an in depth exploration into the chemistry and applications of everyday household waste materials. We’ll explore Nitrogen compounds and soluble salts in urine and determine its use and limits in agricultural applications. We’ll cover some exciting new technologies using urine as a chemical feed stock, along with obscure historical uses, including its use application in the natural indigo vat dyeing process.
