Urine as a Fertiliser

Posted Dec 28 2009 5:33pm

The sanitation department in Lusaka, Zambia, is turning urine into a fertiliser.

Urine contains nitrogen, phosphorus and potassium – as well as all eight micronutrients plants need for growth.
Fresh urine  is virtually sterile, and mixed with water in a 1:3 ratio, is an effective and odor-free nutrient.

It is applied using a watering can (without a shower/shower head) to the roots of the plants not the leaves which will be eaten.

One person’s average urine output is enough to fertilise a garden of 280 square metres.
