Guano is a proven plant fertilizer – based on the excrement of sea birds. Can’t urine then also be used for the beds at home?
Dr. Markus Phlippen (52), biologist and gardening expert, explains: “You can definitely use urine as a fertilizer. Above all, plants need nitrogen, phosphorus and potassium to grow and thrive. Urine contains all three substances, above all lots of nitrogen. “
But he warns to be careful, because urine is very concentrated: “You should never use it pure, but dilute it with sufficient water – otherwise the plant will be damaged.
For example, if dogs pee on a lawn, you immediately see a kind of chemical burn. “
