What does human urine contain?
Urine is a biological fluid which is secreted by the kidneys after being filtered by the kidneys. It contains waste that must be removed by the body. She is composed 95% water and 5% urea, minerals and other components.
Urea breaks down into ammonia under the effect of an enzyme, then in the soil and thanks to bacteria, it is transformed into nitrogen that the plants will be able to assimilate.
It is especially magnesium, sodium, trace elements, calcium and even more potassium and phosphorus which are of interest to plants. These are also components that are generally found in fertilizer. They make urine nitrogen fertilizer, perfect for your plants.
If you tend to eat salty, it should be diluted. If you are taking medical treatment, use healthy urine when you wake up or store it for four weeks before using it in the garden.
Plants need three nutrients : phosphorus, nitrogen and potassium. Nitrogen helps leaf growth, phosphorus is good for flowers and fruits, and potassium helps keep your plants healthy. One liter of urine contains 6 grams of nitrogen, 2 grams of potassium and 1 gram of phosphorus. This makes it an effective, free and natural fertilizer.

You then use it during cultivation, during the period of plant growth. It is necessary to water the plants with 2 to 3 times, spacing the watering by two weeks. It is particularly recommended on vegetables which are fond of nitrogen such as spinach, leeks, salads, tomatoes or eggplants. Never exceed 2 to 3 liters of urine per square meter.
