It’s named because the succulent roots in the basement are longer than the yams. Using a vacuum packing machine, the air inside the bag containing the food is evacuated, and the food is stored in a sealed state in a “vacuum” state lower than the atmospheric pressure expectations. Vacuum-packed packaging means removing the air inside the bag and creating a vacuum inside the package.

With the remarkable growth of the agricultural sector, the increasing need to increase soil fertility and promote crop growth is one of the main factors driving market growth. Along with this, the widespread adoption of organic farming as a means of sustainable development to bridge the gap between supply and demand of food is also supporting the growth of the market. In addition, the development of advanced agricultural technology and the increased use of biofertilizers appear to be major factors driving market growth. In addition to this, the expansion of trade activities for crops and products, especially with developing countries, seems to have a positive impact on the market. As another factor, the implementation of favorable government policies to promote the use of nano-fertilizers to maintain flat green spaces and fields, coupled with growing global environmental awareness, is expected to further boost the market. From 2021 to 2026, the global fertilizer market will be calculated from the geometric mean of the compound average growth rate of about 4% (the rate of increase over multiple periods expressed by the rate of increase per unit period). It is predicted to grow at a compound annual growth rate). The global fertilizer market is categorized based on product type, product, product form and crop type. Chemical fertilizer, bio fertilizer, straight fertilizer, nitrogen fertilizer, urea, ammonium nitrate calcium nitrate, ammonium nitrate, ammonium sulfate, anhydrous ammonia, etc. Super phosphate (SSP), Tertiary super phosphate (TSP), other potash fertilizers, potash muriate (MoP), potash sulfate (SoP), by-nutrient fertilizers, calcium fertilizers, magnesium fertilizers, Sulfur fertilizer, micronutrient fertilizer, zinc, manganese, copper, iron, boron, molybdenum, etc. According to a market research report by Global Information, Inc. (Manpukuji, Aso Ward, Kawasaki City, Kanagawa Prefecture), the market size of nitrogen fertilizer will reach US $ 54.9 billion in 2020, with a CAGR of 5.2% from 2021 to 2028. It seems that it is expected to grow. This seems to be due to the growing popularity of commercial agriculture around the world. In the agricultural sector, the demand for nitrogen fertilizers is increasing in order to properly nourish edible crops and increase yields. Agricultural crops such as fruits, vegetables, grains and cotton are undoubtedly the main areas of use for nitrogen fertilizers. The production level of agricultural products is greatly affected by climate change, and the supply and demand of agricultural products changes from season to season. Fertilizer is an important ingredient used in agricultural work to promote the growth of crops, and most of the crops cultivated in the world use fertilizer. Namegata City, Ibaraki Prefecture, where more than 80 kinds of vegetables are harvested annually and supports everyone from the foundation of Japanese agriculture. The city of whereabouts is located in the southeastern part of Ibaraki Prefecture, surrounded by Nishiura and Kitaura in Kasumigaura. It is an area with soil. Hitachi Province (Ibaraki Prefecture) was established by the Taika Reform of 645CE, and there are only five Fudoki in Japan that describe the situation at that time: Hitachi Province, Harima Province, Bizen Province, Bungo Province, and Izumo Province. There is already a description of the whereabouts area in. The city is a region with a warm and mild climate due to the blessings of Kasumigaura and Mt. Tsukuba. In addition, mellow land was formed from many rivers flowing into Kasumigaura. The whereabouts area is a famous place where various agricultural products can be produced regardless of the crop. The sun, water, abundant soil, and areas that have benefited a lot from nature form an industrial system centered on the agriculture, livestock and fisheries industry. As a result, many agricultural, livestock and fishery products can be shipped throughout the year, and it is possible to stably supply foodstuffs to the metropolitan area (consumption area). More than 60 kinds of various products (rice, vegetables, meat (pork, beef, chicken), chicken eggs, river fish) are stably shipped to the Tokyo area throughout the year. In particular, the items with the highest yields are sweet potatoes, potatoes, mizuna greens, and auction, which maintain the highest yields in Japan. “Hitachi no Kuni Fudoki (description of the culture, climate, etc. of Hitachi province; approx. 720 CE)” : Hitachi is a good country with a large country, far mountains, fertile fields, and cultivated Rangeland. Blessed with the blessings of the sea and mountains, the people are at ease and the houses are full. There is no poor man who cultivates rice fields and spins threads. You can get salt in the mountains on the left and fish in the sea on the right. In addition, Kuwahara（Mulberry field）spreads in the rear field, and hemp is cultivated in the front field. It is a place rich in the fruits of Umikawa Yamano no（海川山野之）. However, since there are few high-quality paddy fields (many wetlands), seedlings may not grow if long rains continue. With just the right amount of sunshine, the grain is rich enough. On May 2; 甲子, 713; 和銅6年, Empress Genmei issued an official order to promote Fudoki to the whole country. At this time, the title “Fudoki” was not official, and it was only an order to submit the customs geography of each country together. After that, in the Heian period, Kiyotsura Miyoshi’s “Twelve Articles of Opinion Sealing”, Kinmochi Yatabe’s “Nihon Shoki Shiki”, and “Fudoki” in 925, etc. It is believed that in the Heian period, it came to be called by the generic name “Fudoki”. The official order of Fudoki is, “Write your favorite characters for the names of the counties of the seven provinces of Kinai. And record the story of the land, the reason for the name of Yamakawa Wilderness, and the old story of the old man’s biography.” To make this official order easier to understand, the name of the county town is written in a favorable character (two kanji characters), a list of minerals such as silver and copper, plants, animals, fish, and insects in the county, the fertile state of the land, the place name of the mountain river wilderness. It describes the origin and the old story that the old man tells. In each country, it is probable that the survey was conducted on a county-by-county basis and submitted by each gunji; district governor (Ritsuryo period: Various institutional designs for running the country are carried out within the legal framework of the Ritsuryo. For example, if it is a famous policy of the Nara period, the state will distribute the cultivated land “allotment of rice paddies for cultivation during the cultivator’s lifetime : The basis of the ancient land system” and “Taxes in kind or service system” to collect taxes from each individual. Province-district-neighbourhood administrative divisions: The whole country was divided into more than 60 countries, and the country was further divided into counties and counties into villages. In the village, 2 to 20 village is one county. The country sends a policy officer (under the ritsuryo system, any of a group of officials, esp. The director) from the capital, and the county assigns the local powerful family to the district governor. Carrots and villages select the influential people there, “chife of village”, and various basic systems up to the military and official positions.) to the Kokushi; provincial governor (under the ritsuryo system, any of a group of officials, esp. the director), who is in charge of compilation. After that, it is thought that the editing of the submitted reports of each county began based on the ideas and compilation intentions of each country, and the climate record for each country was born. Fudoki has been passed down beyond the time of 1300, and now only five countries have been told. You can see how difficult it is to pass on old records to posterity. The five traditions that have been handed down are “Hitachi”, “Harima”, “Izumo”, “Bungo”, and “Hizen” from the east. Of these five Fudoki, the only one that has been handed down in its entirety is “Izumo no Kuni Fudoki”, and the time of creation and the editor are clear. At the end of the book: 天平五年（735年）二月三十日 勘造 秋鹿郡人; アイカノコオリ 神宅臣金太理; かんやけのおみかなたり 国造帯宇郡大領外正六位上勲十二等 出雲臣広嶋とあり: It can be seen that it was created in 733 by the county priest Kanyake no Omikanatari under the supervision of Izumono Omihiroshima. There is also a theory that it is considered to be a reprint because it has been 20 years since the apology was issued. The other four Fudoki are incomplete, but are treated as valuable materials that tell the story of the time. Among them, “Hitachi no Kuni Fudoki” is the only description of the eastern country, and is used as a reference when considering the ancient eastern country. It is thought that Fudoki was created in more than 60 countries nationwide during the Nara period, but nowadays, “Izumo Kuni no Fudoki” (complete), “Hitachi no Kuni Fudoki”, “Harima no Kuni Fudoki”, “Hizen no Kuni Fudoki”, It seems that only the five Fudoki of “Bungo no Kuni Fudoki” (part) are reported. The description varies from country to country, but most of the “Hitachi no Kuni Fudoki” is written in splendid sentences with the 46 Pianwens used in Tang (China) and songs written in Manyogana. In addition, since it is the only remaining climate record in the eastern country, it seems to be an indispensable document when considering the situation in the eastern country at that time. It is also peculiar that many Japanese Takeru appear and that there are many descriptions of gods, especially the description of Kashima District, where the great god of Kashima is enshrined. This is related to the theory that the center of compilation was Fujiwara no Umakai-Ko. 昔, 難波の長柄の豊崎の大宮に天の下知ろし食しし天皇（孝徳天皇）の御世の白雉四年に, 茨城の国造 小乙下 壬生連麿みぶのむらじまろ、そして那珂の国造: 大建: 壬生直夫子; みぶのあたひをのこらが, 坂東惣領高向大夫; ばんどうたかむこのまえつきみ, 中臣幡織田（連）大夫; なかとみのはとりだのむらじ達に申し出て, 茨城と那珂の郡からそれぞれ八里と七里, 合計: 十五里（七百余戸）の土地を提供して, 郡家を置いて, 『行方郡』としたらしい. A long time ago, when the emperor of Takeru was patrolled under the heavens and turned north from Kasumigaura, when he passed this country and went to Izumi Kiyoizumi in Tsukino, he cleansed his hands with Shimizu and opened a well with a ball. It was a compliment. This is called Kiyoi of Tama, and it is still in the village of whereabouts. In addition, he traveled by car to the country and offered food to God on the hills of Arahara. At that time, the emperor wanted to see all sides and said to the chamberlain. “The scenery you see while walking out of the car is that the mountain ridges and the sea coves cross each other, undulating and winding. The clouds over the peaks and the fog that sets toward the valley. They are lined up in a stunning arrangement and have a delicate beauty. That’s why the name of this country is called a line-up ridge.” Hisashi Namekata later became known as Namekata. 諺に “立雨たちさめふり, 行方の国” といふ. In addition, this hill was named Arahara because it is a hill that can be seen very high from the surroundings. When I went down this hill, went out to the Omasu River, and climbed the river on a small boat, the paddle broke. Therefore, the river is called Mukajigawa River. It is a river that flows through the border between Ibaraki and Namegata. When I went up the Mukaji River to the county border, a duck was about to fly. As soon as the emperor shot the bow, the duck fell to the ground. That place is called Kamano. The soil is thin and there are no living vegetation. To the north of the field, there is a deep forest where Ichii, Kunugi, Kaede, and Japanese cypress grow densely. Masu Pond there was dug during the time of Tayu; Chief actor in a No play Takamukai. In the north, there is a shrine dedicated to the god of Katori, and the mountains beside it are fertile and densely populated with vegetation. There are sea pine trees and salt-burning algae in the sea where you can see from the ferry west of the county, but there are no rare fish and no whales. There is an old indigenous company in the east of the county, which is called the prefecture’s Gion. Shimizu in the forest is called Oi, and people living nearby come to fetch water and use it for drinks. A large tree stands at the south gate of the county house. The northern branch hangs down until it reaches the ground, and then rises into the sky again. This area used to be a swamp of water, so even now, when it rains for a long time, a puddle can form in the garden of the government building. Tachibana trees are also flourishing in the nearby villages. There is Tega no Sato in the northwest of the county. A long time ago, it was named in memory of Saiki, who lived in this area and was named Tega. To the north of the village is a shrine dedicated to the god of Kashima. The surrounding mountains and fields are fertile and rich in chestnuts, bamboo, and chives. To the north of the village of Oga, there is a village of Nun. It was named after Saiki, who lived in this area a long time ago. The station house Umaya is now located, and it is called the Soun Station. 昔, いはれ（石村）の玉穂の宮に大八洲知ろし食しし天皇 : In the reign of Emperor Keitai, there was a man named Mr. Yahazu, who cleared the valley west of the county house and the reclaimed rice field, and healed the newly reclaimed rice field. At that time, the gods of Yatsu appeared in a flock and stood on the left and right, so they could not cultivate the rice fields. (Popularly, a snake is called the god of the night sword. The shape of the body is a snake, but it has a horn on its head. , The house is destroyed and the descendants are gone. Usually, they live in groups in the field beside the county house.) Unable to see it, Mr. Matachi wore armor, took a halberd, and confronted him. Then he set up a wand to mark the moat at the entrance of the mountain, and said, “From today, I will be a priest, in order to make the mountain above here a dwelling place for gods and the village below to be a rice field where people can make. , I will honor God and celebrate the festival until the generations of my descendants, so please do not worship or resent me.” Since then, the descendants of Matachi have continued to take over this festival for generations to this day, the number of newly reclaimed rice field has increased, and more than ten towns have been reclaimed. 後に, 難波の長柄の豊崎の大宮に天の下知ろし食しし天皇 : In the reign of Emperor Kotoku, Mibu no Murajimaro ruled this valley and built a pond bank. At that time, the god of the Yatsu climbed up to the vertebrate tree by the pond and did not leave easily. Maro said in a loud voice, “The purpose of building the embankment is to save the people. I don’t know if it’s a god of heaven or a god of nation, but please listen to the apology.” The snake ran away when he tried to say, “Knock out visible animals and fish insects without fear.” The pond is now called Shiii no Ike（Next to the old man Ikoi’s house in Tamatsukuri Town Izumi）. There is a vertebrate tree on the edge of the pond, and there is also a well where fresh water comes out, which was taken as the name of the pond. This is the overland station road to Kashima. Odaka no Village is located seven Village south of the county. It was named after Saiki, who used to live in this area and was named Odaka. A pond was built during the time of the Hitachi National Guard, Tagima（当麻）chief actor in a No play, and it is still east of the road. In the mountains west of the pond, there are many vegetation and many indigo plants and monkeys. Whale oka, south of the pond, is a place where whales have come all the way to this point and lie down and die. To the north of the pond, there is a shrine dedicated to the god of Katori. It became the name of the pond because there was a large chestnut tree called Kuriya no Ike. In the village of Aso, hemp used to grow at the water’s edge. The hemp was as thick as bamboo, and was more than one length long. Castanopsis, Chestnuts, Zelkova serrata, and Taxus cuspidata flourish, and ino and monkeys live there. Horses that live in the field are for horseback riding. In the reign of the emperor (Emperor Tenmu), who ate at the Omiya of Kiyomihara in Asuka, the life of the county’s university student, Ohofu no Sato, presented the horse in this field to the imperial court. Since then, it has been called the “Missing Horse”. The horse of Ibaraki no Village is called “Ibaraki no Vintage no Horse”. Kasumi no Sato is located 20 ri south of Gunya. In the old biography, Emperor Keiko, the courtier of Shimousa, when he climbed the hill of Torimi, walked slowly and looked at the country, turned to the east and said, “The blue waves in the sea. You can see this country as soon as it springs up from the red haze that flutters on the land,” said the samurai. From this time on, people came to call it “Human Township”. The shrine in the eastern mountain of the village is full of enoki, camellia, camellia, vertebrate, bamboo, salmon, and arrowheads. The island in the sea west of the village is called Niihari’s island. It was named because if you stand on the island and look far north, you can see the mountains of Tsukuba in Small Tsukuba, the country of Niihari. There is a village where you want to come to Ita, located south of Kasuminosato. A station house is placed at a nearby seaside ferry, and it is called Itarai station house. To the west is a forest of celtis sinensis. This is the place where Omi, the king of Omi King, lived in the reign of Asuka Kiyomihara’s emperor (Emperor Tenmu). Many salt-burning algae, sea pine, surf clams, spicy clams, and clams live in the sea. A long time ago, Takekashima Mikoto was sent to the reign of the Emperor Sujin (Emperor Sujin), who ate at the Mizugaki Palace in Shiki, in order to speak to the raging thieves of the eastern country. When Mikoto set up an inn on the island of Aba, while leading the army to the thieves, he saw smoke as he looked far into the eastern ura of the sea. The soldiers suspected that this was a thief army. Mikoto looked up at the heavens and swore, “If it’s the smoke of a heavenly man, come and cover me. If it’s the smoke of a raging thief, go away and go to the sea.” The smoke flowed far towards the sea. Knowing that he was a thief, he ordered all the soldiers to finish breakfast early, and the army crossed the sea. Meanwhile, Kuzu, Yasakashi, Yatsukushiha, and the chief of the thieves, dug a hole, built a small castle, and lived there. When Mikoto fired his troops and expelled them, he fled to the small castle all at once, closing the gate tightly and standing up. Immediately make a plan, select brave soldiers to hide in the depressions of the mountain, build weapons and arrange them in the beach, line up boats, knit rafts, flip the caps of clothing with clouds, and rainbow the flags. Ama no Torikoto and Ama no Torifue sang and danced the first song on Kishima Island for the first time in seven days and seven nights, and enjoyed playing with the sound of the waves. Hearing this fun song and dance, the thieves came out with their families and men and women, and flocked to the beach and laughed happily. Mikoto had his cavalry block the castle, attacking thieves from behind, capturing them, and setting them on fire to destroy them. The place where I said painfully was the town of Taku (Itarai) now, the place where I said that I would slash normally was the village of Futsuna, and the place where I said that I would slash cheaply was the village of Yasukiri, and I often slash. That is Esaki’s eup. In the sea south of Itarai, there is a shore of about 34 villages; about 132 km. In the spring, men and women come from Kashima and whereabouts to pick up clams, surf clams and various other shellfish. Tohoku no native place is located 15 villages to the northeast of the county. A long time ago, when I visited this town during the procession of the Emperor Takeru, Torihi Torihiko, whose name was Saeki, rebelled against his life and defeated him. He then headed for Yagatano’s Book Palace, but the road was narrow, rugged (rough), and rough, hence the name Toma. The soil in the field is thin, but purple grows. There are also two companies, Katori and Kashima. In the surrounding mountains, there are forests of wild boars, hahaso, chestnuts, and shiba, and many wild boars, monkeys, and wolves live there. To the south of Toma, there is the art capital, Kitsunosato. A long time ago, there were two Kuzu, Kitsuhiko and Kitsuhime. In front of the emperor’s pilgrimage, the princess turned against Mikoto, disobeyed herself, and behaved in a very rude manner, so she was killed with a sword. The princess was terrified and fell down on the side of the road with a white flag, and welcomed the emperor. The emperor mercifully gave her grace and forgave her house. As she goes further on her ride and goes to Onukino’s palace, she takes her sister with her, and she does her true heart on rainy and windy days. I finished it in the morning and evening. The emperor was delighted with his lonely appearance, and his love became a stain, so he called this field Uruhashi Ono no. There is a rice field village to the south of the art capital village. In the reign of Empress Jingu, a person named Kotsuhikoto was sent to Korea three times. It became the name because it was given a rice field for its achievements. The field of Hazumuno no was named after Yuhazu was built in the temporary palace of the emperor of Takeru. There is a branch of the god of Kashima on the seaside north of the field. The soil is thin, and elms, elms, elms, bamboo, etc. are sparsely grown. There are Auka and Oho villages to the south of the rice field village. A long time ago, when the emperor of Takeru stayed at Kazakinomiya in front of the hill of Auka, he built Ohido no on the urabe and connected small boats to go to Gozaisho as a bridge. He named Ohohikara, Oho. Also, Ohotachibana no Mikoto, who was after the emperor of Takeru, came down from Yamato and met the emperor here, so it is called Afuka’s eup. Tanakiyonoi : According to the whereabouts of “Hitachi no kuni Fudoki”, “Hunting under the heavens of Emperor Yamato Takeru and conquering the north of the sea. Fortunately, he faced the water, washed his hands, and prospered the well with balls. He is still in the village of whereabouts and is called Tamakiyoi.” Even though it is a well, it is now like a pond in a garden. According to the monument of “Tamakiyoi” by Mr. Tsutomu KURITA, which stands nearby, it is said that it was dug by the villagers during the famine of Tenmei. 常陸国風土記の記載内容-行方郡-A long time ago, when the emperor of Takeru was patrolled under the heavens and turned north from Kasumigaura, when he passed this country and went out to Shimizu in Tsukino, he cleansed his hands with Shimizu and opened a well with a ball. It was a compliment. This is called Kiyoi of Tama, and it is still in the village of Namegata. “Chinese yam; Nagaimo”, The history is very old and seems to date back to BC. There are records that it was used as a condiment in Yunnan Province, China. It is said to have been introduced to Japan via the Korean Peninsula, and is a traditional nourishing vegetable that has been cultivated since ancient times. There are various names for dioscorea, and it is easy to confuse the types, but botanically it is classified into the yam family, the genus Dioscorea. Of these, “Nagaimo” is edible in Japan, “Natural yam” that grows naturally in the mountains, and “Large Yam” that is cultivated in small quantities in Kyushu and other areas. There are two types of “long yam”, “Ginkgoimo”, and “Tsukuneimo”. The long potatoes are straight and long, and have a lot of water. The latter two types are different in shape from the long potatoes and have strong stickiness. In Honshu, Aomori prefecture, “Ibaraki prefecture”, Tottori prefecture, etc. are the main production areas, and Hokkaido is also a famous production area. The cultivation period of long potatoes is about half a year. It is a rhizome plant that grows up to about 1 m in deep ground. Therefore, it takes a lot of time and effort for both planting and harvesting. At the time of planting, a large machine called a trencher (grooving machine) digs about 140 cm and mixes the red soil on the surface with the black soil in the heart soil to make the soil fine and well-drained. After that, a basket full of seed potatoes is placed on a seedling planting trolley with an engine, and one plant is planted sideways between 23 cm plants suitable for cultivation. At the earliest, planting of one field is completed in one day. Then, mulch for heat retention is put on the embankment, and 3 m columns are buried in the ground at regular intervals to complete. At the time of harvesting, after removing the pipes, mulch, and vines on the ground, the sides of the ridges are dug at least 1 m with Yumbo, and the potatoes in the soil are harvested one by one by hand. After that, the harvested dioscorea opposita is covered with a sheet to prevent the soil from drying, and it is washed, cut, and vacuum packed for 2 days. At the beginning of digging, potatoes（tuber）with a length of nearly 1 m are cut into pieces of about 20 cm each, considering the time and effort of cooking at home. “Each one is perfect in thickness and length, but if you can get 3 to 4 packs, it will be good.” Japanese Yam has an appropriate thickness and length, and there is a high demand for those with smooth and beautiful skin. In soil preparation, a crop rotation system that grows multiple crops in one field is recommended as a countermeasure against continuous cropping obstacles, and it is said that sorghum, a green manure crop, will be used to restore soil fertility when the fields are vacant. In addition, it seems that the direction of the ridges will be remade vertically, horizontally and diagonally each time it is planted. I heard that as a result of intentionally leaving the hard soil and guiding the roots toward the soft soil, straight Japanese yam with beautiful skin grow. Low-acid foods packed in containers and packages are foods that are sealed at room temperature and have a pH of over 4.6 and a water activity of over 0.94, and have been sterilized at 120 ° C for less than 4 minutes. Botulinum food poisoning appears to be caused by ingesting foods containing toxins produced by Clostridium botulinum. It seems to be a serious illness that makes things look double, makes it difficult to apply force to the limbs, and if left untreated, causes dyspnea and is fatal in a short time. Clostridium botulinum is widely present in soil and water. It is very resistant to heat and cannot be sterilized even if it is heated for a long time at about 100 ° C. It grows in a sealed state with very little oxygen, like a vacuum pack, and produces toxins. For this reason, it is necessary to take measures such as heating the sealed food at 120 ° C for 4 minutes or the same method, or refrigerating it. This product is pre-cooled and compatible.
