While money is being spent on quality fertilizers for plant growing today, things did not work this way many years ago. Humans were known to use their own urine as a fertilizer target in plant cultivation. Well, what kind of results does the method of using urine as fertilizer, which is generally negatively received today, give results in the current rules?
In pursuit of this, scientists from the National Institute of Agricultural Research in Niger followed this procedure, which is used in some Asian regions. Within the scope of the research, a group of Nigerien women were willing to have their urine used as fertilizer in the fields. The women were divided into two clusters and one cluster used urine as a fertilizer, while another group continued to use the traditional fertilization methods in the region.
Urine provided 30% higher efficiency than conventional systems:
Urine containing phosphorus, potassium and nitrogen was of course not given to the plants as it is. In order to destroy the pathogens found in the urine, the urine was kept in boxes at a temperature of 22 – 24 degrees Celsius for two to three months. The women started using urine with organic fertilizers in the first few years of the study. When success was achieved here, it was passed to the next stage, that is, using only urine.
In a total of 681 observations made between 2014 and mid-2016, it was discovered that urine increased efficiency by 30% compared to the classical method. In fact, Niger farmers, who saw the difference, started to move away from classical methods and use only urine. Although the results of the research on the subject of kalam were published in July 2021, it shocked the scientific world. Moreover, a study published in February 2022 showed that the USA, Australia and Sweden are also starting to try this method to increase sustainability.
