\u3000On the other hand, in Yamagata and Miyagi prefectures, there are various local varieties of taro. In both prefectures, taro stew parties are often held on riversides in autumn, and have become an autumn tradition. For example, in inland Yamagata Prefecture, beef is usually used in the soy sauce flavor, while pork is usually used in the miso flavor in Miyagi Prefecture. Although individual differences in taste and perception of flavor are likely to be significant, the influence of soil physical and chemical properties on flavor is not insignificant. In this paper, we conducted a soil survey of taro (a local native variety) production areas in Yamagata and Miyagi prefectures as a clue to considering the relationship between soil physical and chemical properties and flavor.<\/p>\n\n\n\n

\u3000First, a bird's-eye view of the main local taro species in Yamagata and Miyagi prefectures is presented. All of them are well adapted to the soil and climate of their respective regions, but their exact origin is not always clear. The taro is often characterized by its \"stickiness\" or \"stickiness. Some people also cite the taro's inherent sweetness and the rich earthy aroma that permeates the nose.<\/p>\n\n\n\n

\u3000Jingoemon taro: This is a local variety that has been passed down from generation to generation by the Sato family of Osawa, Mamurogawa-cho, northern Yamagata Prefecture, under the family name \"Jingoemon\". This taro is considered to belong to either the red-bud variety or the karaimo variety, and when cooked in taro stew, it is soft and sticky to the touch, but has a light texture on the palate. However, the yield is a little lower than that of economic varieties.<\/p>\n\n\n\n

\u3000Zao Town in southern Miyagi Prefecture is a major producer of taro in the prefecture, and various strains exist, with the Shimobetsutou area being particularly famous. Because of its topography, the Shimobetsudo area is less prone to frost damage, and the soil is typical volcanic ash soil. The potatoes have a sticky texture, and it is said that this stickiness cannot be obtained if the potatoes are grown in other areas.<\/p>\n\n\n\n

\u3000Ibano sweet potato is a local species that has been handed down in the Kami-Ibano district of Sanbongi-cho, Osaki City, Miyagi Prefecture. According to \"Comprehensive Guide to Local Vegetables by Prefecture\" (2002, No Bunbun Kyokai), it is called \"Dodaru\" type. It is soft and sticky, and is suitable for various dishes. However, its yield is slightly lower than that of economic varieties. It is characterized by its reddish pattern. It is important to note that once a field is planted, it should not be planted again for three years.<\/p>\n\n\n\n

\u3000As described above, although all of the taro varieties investigated in this study were renowned for their production area and reputation for excellent taste, no clear relationship was found between the soil properties of each taro production area and the taro varieties. This suggests that the effects of soil physical and chemical properties on the growth of taro and its flavor and taste may not necessarily be in sync with each other. Some producing regions have their own secrets in soil preparation, and some of the respondents said that it is a \"trade secret\" so to speak.<\/p>\n\n\n\n

\u3000It is highly likely that the physical and chemical properties of the soil affect the flavor and taste of taro, but since the sampling in this study was limited to a very small area in each production area, it was not possible to make a good relationship between the two. Further studies will clarify this aspect by increasing the number of samples, analyzing the components of the harvest, and carefully conducting sensory tests.<\/p>\n\n\n\n

\u3000The compound resulting from the decomposition of urea is thought to exist in the soil in the form of ammonium carbonate. Ammonium carbonate, which is inherently slightly alkaline, is easily autolysed into ammonia and carbon dioxide. If urea-derived ammonia is not nitrified quickly, it can easily cause ammonia-induced root burn symptoms and ammonia gas injury.<\/p>\n\n\n\n

\u3000This phenomenon does not occur with ammonium sulfate. Ammonium sulfate is a weakly acidic compound in which ammonium ions are combined with sulfate ions, so it does not form free ammonia. Urease is a unique enzyme that degrades urea in the pH range 6.5 to 7.5 and is active even in alkaline conditions. In this pH range, the activity of nitrifying bacteria decreases while that of urease does not, which is one of the reasons why the rates of urea degradation and nitrate formation are not synchronized.<\/p>\n\n\n\n

\u3000Photos of lettuce being grown on board a spacecraft and eaten by the crew can be found on the Internet.
\u3000Growing vegetables in space is probably intended to ensure self-sufficiency of fresh vegetables for a long stay in space, but the healing effect cannot be overlooked. It is thought that this is one of the methods to regulate the increase of carbon dioxide concentration in the spacecraft by fixing a part of carbon dioxide gas, which is estimated to be generated from the breath of an adult male at about 0.7 kg\/day\/person, with plants, and the generated carbon dioxide gas is absorbed and separated, and released outside the spacecraft.<\/p>\n\n\n\n
