With the goal to have a more sustainable and ecological centre hydroponic agriculture with urine as fertilizer is carried out. The principle is simple: a layer of sand (10 cm) is laid on a plastic sheet and a slope allows the liquid fertilizer to flow slowly from the top to the bottom of this layer.This technique has many advantages such as- very little labour force needed, little water wasted with good yield. To get rid of the issue of chemical fertilizer, urine is used. It is free, reasonably safe to handle and contains the elements required for the plants to grow. We call them fertilizer and the three most important are Nitrogen, Phosphorus and Potassium (NPK).
