Using seafood as fertilizer ... Guano's crisis

Using seafood as fertilizer ... Guano's crisis

Do you know the word "Guano"?



Seabird manure deposited on the coasts and islands of arid tropical regions, rich in nitrogen and phosphoric acid, and an effective fertilizer. In the 19th century, guano was used as a fertilizer in large quantities in Europe and was initially imported from the northwestern coast of the African continent, but the coast of Peru is home to a large number of fish. There are many seabirds that feed on it, and guano that reaches several tens of meters has accumulated on its coasts and islands, and it has become known to be of good quality and abundant, so it was mined in large quantities using dynamite from around 1840.Began to be exported to Europe. (Also called Guano) The benefits of Guano have brought about the prosperity of Peru, especially the once-declining capital Lima. Having noticed this resource, Spain occupied the Chincha Islands off Pisco in 1863. Peru, in cooperation with Chile, repelled Spain in 1865, but was liable for its war costs. Until around 1870, 9 million tons of guano were dug up in about 30 years, and now only a small amount remains.


Guano is also called "bird droppings", and its origin is the Quechua word "feces". Although it originates from feces, it is a fine mineral. Mining with dynamite must be lamented by Nobel.

Also, in terms of its use There are two types of guano, "nitrogen guano" and "phosphoric acid guano". The former is formed in arid areas with low rainfall and low humidity,  and contains nitrogen minerals. The latter is formed in areas with relatively high rainfall and humidity, such as tropical and subtropical areas, and nitrogen is discharged and phosphoric acid is concentrated due to long-term rainfall. Both are indispensable for the modern chemical industry (chemical fertilizer), and the former was mined in large quantities as Nitratine in Chile and exported to Europe. This enormous profit temporarily brought a boom to Chile,  but declined due to resource depletion and the establishment of a method for producing artificial nitrogen fertilizer by chemical nitrogen fixation in Germany in the early 20th century.

The latter was the most important phosphorus resource until the discovery of phosphate rock. Many of the former mining sites have already been dug up and depleted, as they are abundant on the islands of the South Sea and do not exist in large quantities as resources.

From wikipedia

With the war over Guano (Chile vs. Bolivia) and the intervention of the United States (Guano Island Law), you can see how important it is as a material.

Deposits that are important as phosphate ore resources are classified into three types according to their origin.

1) Fossil deposits It is a relatively large phosphate ore deposit that originated from ancient flora and fauna and microorganisms, and exists in the United States, Morocco, Jordan, etc. Most of the current phosphate ore is supplied from this deposit.

2) Guano (both bird coprolite and fecal phosphate rock) deposits See separate section. It existed in Nauru and other places.

3) Ignition deposit There is a large-scale phosphate deposit on the Kola Peninsula in Russia, which is the same inorganic phosphate ore deposit as the metal deposit caused by crustal movements.

Phosphate ore is distributed all over the world, but its price was extremely low, so it was necessary to reduce the production cost by large-scale development. For this reason, it often depends on the huge deposits of a particular country. In the past, Japan purchased large quantities mainly from mines in Florida, the United States, but in the latter half of the 1990s, imports decreased as the United States embargoed due to resource depletion.

As an alternative destination, it began to be purchased from a mine in Sichuan Province, People's Republic of China. However, from around 2005, when speculative funds flowed into the futures market in general, the international price of phosphate ore also rose.

As if to catch up, the production volume dropped sharply when the Sichuan earthquake struck in 2007. China's 100% tariffs on phosphate rock to control domestic fertilizer prices have caused international prices to skyrocket and disrupt the market. In the case of Japan, a price increase of 50% or more was seen around the summer of 2008 on a chemical fertilizer product basis. It should be noted that phosphorus collection itself can be technically collected from industrial waste such as activated sludge and steel slag without relying on ore, and it is debatable whether it can be positioned as a strategic material.

This is also from Wikipedia. ( Bullets by Morishita)

I heard that "phosphate ore" itself is almost depleted. Is only Guano depleted? A remarkable feature of this guano is that the seabirds (Umidori) that ate sea fish concentrated the beneficial minerals in the seawater and dropped them on land (Megumi:Giving). If you leave it alone, I think that Guano was the endless essence that birds have just acted as pumps to drop minerals that do not go to land from seawater. By their work, the material cycle between the sea and the land was carried out.

Phosphorus is a constituent element of ATP, which controls energy metabolism, and DNA, which is a gene, and phosphorus is one of the important pillars of life activities. If you go there, human beings have not produced phosphorus even if they consume phosphate ore. How about this? …Instead of the depleting phosphate rock, it is possible to fetch seaweed and fish from the sea and plow them into the fields. It will be a mineral-rich fertilizer.

In fact, there are people who live on the beach and bring seaweed to practice such things, and it is also because small fish in the sea (especially sesame sardine) were also called "tazukuri"(Making the paddy). Now, humans should be "mineral pumps". It's better if you eat seafood and then use the waste products that are discharged. Since modern times, human beings have been wasting too much Nitrogen(chisso) and phosphorus due to the spread of sewerage.

A word of the day: However, you have to take the risk of containing harmful minerals (such as cadmium and mercury) as well as useful minerals. However, if you have depleted the phosphorus resources that are essential to life, it seems that there is only this plow-in method. ...,

and the difficult problem of marine pollution caused by this Fukushima Daiichi nuclear power plant has also arisen. It may not be possible to plow in marine products containing radioactivity in contaminated areas. If the sea is also contaminated with radioactivity ... barren sea, barren land. ...

Furthermore, human waste (sewage or human waste: feces and urine) that was originally supposed to circulate on the ground is also radioactively contaminated with deformed sludge (activated sludge), leaving nowhere to go. I will. This means that the earth will be uninhabitable for humans. Oh, is sinful the weakness of humans who rely on nuclear power?

熱帯の乾燥地域の沿岸や島々に堆積した海鳥糞で、窒素・リン酸分に富み、有効な肥料である。19世紀に入って、グァノが肥料として、ヨーロッパで大量に用いられるようになり、はじめは、アフリカ大陸の北西岸から輸入されたが、ペルーの沿岸には、大量の魚が生息し、それを餌とする海鳥が多く、その沿岸や島々には、数十メートルに達するグァノが堆積し、良質で豊富であることが知られるようになったため、1840年ごろからダイナマイトを使って大量に採掘され、ヨーロッパに輸出されはじめた。 (グアノとも呼ぶ)


http://www.tabiken.com/history/doc/F/F112R100.HTM  より。なお、グァノは、「鳥糞石」とも言い、ケチュア語の「糞」が語源です。糞が起源とは言え、立派な鉱物です。ダイナマイトを使って採掘とは、ノーベルも嘆いていることでしょうね。
