Reuse of urine - fertilised and not fertilised basil experiment part I

Reuse of urine collected at an office building in Eschborn, Germany with urine-separation toilets. The right plants are not fertilised, while the left plants are fertilised with urine. The fertilised plants are stronger, taller and have a stronger green color of the leaves. The bottle contains the collected and stored urine.

 

In order to see the effect of urine fertilization more clearly, we used very nutrient-poor soil: it is a 20/80 mixture of sand and of clay granules (to hold moisture).
