A team of researchers from several institutions in Niger, Germany and the United Kingdom have conducted hands-on tests on the use of human urine as a natural fertilizer for crops.In their paper published in the journal Agriculture for Sustainable Development, This group describes experiments conducted on female farmers in the Republic of Niger and the use of human urine.

For thousands of years, humans have known that their urine is an excellent fertilizer for crops.including Rin, nitrogen When potassium— Many of the same ingredients as commercial fertilizers. However, its use is limited due to the squeaks associated with growing crops using urine. Still, many gardeners know its benefits and are used around the world to help people grow healthy foods for their families. In this new initiative, researchers wondered if human urine could be used on a larger scale, such as on farms growing crops for sale. They sought the support of a group of women living in isolated areas of the Republic of Niger.The farmers there have been struggling to fertilize them for years Pearl millet It is hampered by the cost of grain crops, commodities and the lack of animal manure.

The first step in the experiment was to rename the urine because its common name was considered unpleasant. They settled down in Oga. Then they divided the farmers into two groups. One ran the farm in the traditional way and the other used Oga to fertilize the wheat. Over two growth periods Yield Measured in both groups. A second group of 27 farmers, Oga, was provided by the farmers themselves who were taught how to pasteurize, store and dilute urine for use as fertilizer. They also added a small amount of animal manure.

Data collected from farms showed that those fertilized with Oga produced an average of 30% more grain than traditional farms. Researchers say the difference was so great that other women in the area began to emulate them in experiments. Two years after the experiment, they found that more than 1000 female farmers were using Oga to fertilize their crops.
