Many wonder whether the use ofurine come fertilizer is just a myth or a valid method. In this article, we will look at the effectiveness of this unusual approach to fertilization, based on scientific evidence e in-depth studies.
In an era where theself-sufficiency and the sustainability are increasingly valued, many farmers e gardeners they are looking innovative solutions to improve the soil fertility without resorting to chemical fertilizers.
One of the oldest and, at the same time, least known methods is the use ofhuman urine as a fertilizer. But is this approach really effective or is it just a myth?
Nutritional values of urine
L’urine contains a series of fundamental nutrients for them plantcome of nitrogen, of phosphorus e potassiumwhich are also the main components of commercial fertilizers.
Humans have been using urine as fertilizer well before the invention of modern chemical fertilizers. Urine can be considered a sort of “liquid gold” natural and free.
Production and use of urine
According to Stockholm Environment Institutea person can produce enough urine in a year to fertilize 300-400 square meters of crops.
In a domestic setting, the urine produced by a household may be more than enough to maintain a vegetable garden. On a larger scale, the use of human urine could address problems of healthcare e food safety all over the world.
Composition of urine
L’urine is composed of approximately 95% and water and the remaining 5% from a mixture of sali e organic compounds. These include urea, sodium, potassium e uric acid. L’ureain particular, is rich in of nitrogenan essential nutrient for plant leaf growth.
In addition, urine contains of phosphorus dissolved that is immediately available to plants, making it a fast-acting fertilizer.
Social and environmental benefits
L’environmental impact of the production and use of chemical fertilizers it is well documented. For example, the of phosphorus, a key ingredient in commercial fertilizers, is typically extracted from limited resources. Excessive use of fertilizers can cause algali fioriture e dead zones in aquatic systems.
Use urine as natural fertilizer can help reduce these problems and create a closed loop system which turns waste into resources.
Is it safe to use urine as fertilizer?
Despite theurine is not sterile, the health risk associated with its use as fertilizer it is very low. Unlike the I didurine typically does not contain pathogens.
However, it is important to monitor the health of the person producing the urine and avoid use if you are taking it drugs or treatments hormonal. Also, if urine is used in arid areas, care should be taken as to the possible soil salinization.
How to use urine in the garden
To use urine as fertilizersome precautions must be followed:
- Store or handle urine in a closed container.
- Apply urine directly to the soil and not to plants.
- Dilute urine with water in a ratio that can vary from 1:1 a 1:15with the report 1:3 as most common.
Finally, theurine It can also be used to speed up the process composting. Adding urine to the compost can help heat the pile quickly due to its high content of nitrogen.
There are scientific evidence in support of the use ofurine come natural fertilizer. However, it is essential to apply it in moderation to avoid damage to plant.
With the right precautions, urine can become a valuable resource and sustainable per i gardeners they farmers of all the world.
