The use of human feces as fertilizer is not common in the world. In many countries / ethnics, dropping manure into fields that produce human food has been avoided. For example, it is said that Ainu people did not get used to agriculture quite easily in the Meiji period, The biggest problem is said to be the use of manure as fertilizer. In the Muromachi era, the Korean communication envoy It says that the output of crops is very high. " In the Edo period, the value differs depending on the class that produces the human waste, Human feces taken from a well-fed hierarchy (the top layer is Edo Castle), It was taken at a higher price than the one below it (the bottom one is a sinner). The human waste from Edo Castle is Shaanxi village had monopoly. The common toilet attached to the Nagaya is It is installed to collect these fertilizer raw materials efficiently. The farmland around the castle town is greatly fertilized with fertilizer obtained from here, We continued to provide food to the townspeople. In Edo Rakugo there is a depiction of a dumping line saying, "I will not excrete again in a long-time house!" It is because there is such a background.

We will also introduce how to use in the kitchen garden. Long ago, It is well known that human urine was always used for farming, but So why not use it now? In one study, Where human urine was used as fertilizer to grow vegetables It seems that larger vegetables are made than vegetables using chemical fertilizers. There was no difference in the nutrition and taste of the vegetables themselves, so After all, urine had an effect as a fertilizer. Many of the currently used chemical fertilizers Contains nitrogen and phosphorus and potassium. Is this really harmless? Because we continued to use a lot of such chemical fertilizers, In some cases, high concentrations of nitrogen were detected in drinking water. Chemical fertilizers are harmful to humans and animals. So why hasn't human urine been used today? First of all, there is a toilet situation. Now all stools and urine are flushed together into the sewage system. It is not possible to collect only urine. Also, because urine is excreted, If it is not mixed with the flight, You can use it for home gardening with confidence. When you try to use it yourself, Remember to dilute it 10 times with water before using it. Also, if you are making compost yourself, If urine is mixed there, it seems that nutrition will increase.
