Lo principal que debes saber es que la orina debe mezclarse con materiales ricos en carbono para que pueda actuar y el nitrógeno quede disponible para tu planta. Si tienes un sustrato preparado debería ser suficiente. En caso de que no lo tengas, mejor utilizar la solución de humus de lombriz.
He recopilado varias fuentes de jardinería y agricultura sobre el uso de la orina y lo he probado en mis cultivos en casos de no poder comprar fertilizante. Las fuentes dicen que la orina de las personas sanas está libre de patógenos, que los únicos casos a evitar es si la persona carga con una enfermedad o está tomando medicamentos.
En el resto de los casos la orina es prácticamente similar entre una persona y otra. Sobre todo en sus altos niveles de nitrógeno y su composición ( N-P-K 11-1-2.5 aproximadamente ), que también es similar a los fertilizantes que puedes comprar normalmente.
How to use diluted Urine
- Pee in a plastic bottle 😛
- Dilute it with water, 1 part urine every 10-15 parts water. For example, if you put 1 liter of urine, you dilute in 15 liters of water. In 100 milliliters in 1.5 liters.
- Remove a small layer of soil taking care not to damage the roots
Water with diluted urine as you would normally water.
- Refill the soil layer.
- Water again with plain water.
Removing the earth allows you to avoid bad odors and make better use of nitrogen, by achieving less ammonia generation.
Remember that irrigation water should always be left to stand for at least 24 hours to clean it of chlorine and other elements.

The Other Look
My friend Vicky, a Trimix manager and experienced grower, saw this guide and quickly said, “I don’t recommend it.”
“The use of urine as a fertilizer is very common, but it hides some key points to keep in mind that they can make things go wrong. Urine, basically, is filtered waste. What does not work in our body, the kidneys expel it.
The urine can contain pathogens, hormones, remnants of medicines and a lot of things that can be negative for our culture, especially if we apply it to any type of plant that will later be consumed.
In case of using urine as a means of fertilizer for our cultivation, it is of utmost importance to ensure that, not only do you have healthy physical conditions, but you must also make a healthy and light diet (practically, vegan).
Another way to reduce pathogenic risks is by storing urine for at least one month. The problem is that sometimes the deficiency in the plant cannot wait.
It is a valid method, but it is important to use extreme conditions to avoid risks.
A humus bag is very inexpensive and can solve the problem in the same way. Personally, it is my favorite method ”
I highlight your opinion for two things. There are many people who think this way, and whenever you go to do something to your plants you will want to be as informed as possible.
I do share with Vicky that the worm cast solution is a very good one, and comes with other benefits for the soil. In case you are particularly interested in paying with urine, look at the references you leave above and investigate on your own.
What do you think? Would you fertilize with urine? I have done it and my plants appreciated it.
