Thunen’s Agricultural Location Theory: As a farmer, Thunen came up with this theory while thinking about what kind of farmland should be cultivated in order to maximize profits. J.H. von Thunen (1826) The Isolated State on Agriculture and the National Economy. He considers the selling price, the wages, and the transportation costs as raw materials, of which the transportation costs, which are determined by the distance from the market, are the factors attributable to the land itself. For urban consumers, the value of each type of agricultural product is the same everywhere. Value of land = Reflected in land rent, difference from land rent in the furthest edge of the market area = positional difference in land rent, transportation costs, land rent, management method. Only low-cost (= extensive). If you don’t manage it, the market price will be in the red. Farmers who are closest to the market can produce high-priced crops through intensive management that takes “time and effort” as much as they can save on transportation costs. For example, rice cultivation, which is representative of extensive low-cost agriculture in Japan, is most advantageous if it is grown and sold in the immediate vicinity of the market as it does not incur transportation costs. However, no matter how intensively it is grown, rice cannot be sold at a high price due to the high distribution volume. In the immediate market, there is no choice but to switch to agricultural management (horticultural crops) where higher prices can be expected. Agricultural management system: The rate of decrease in rent bearing capacity is steeper for intensive farming and gentler for extensive farming.
The JA Osuzu Mini Tomato Subcommittee received the 34th Japan Agricultural Award in recognition of its creation of a production area through environmental recycling-oriented cultivation that unites the region. The Miyazaki Eco Cherry Tomatoes produced by this group boasts such a strong flavor and consistent quality that it is as if they were born from the tropical sun, and are so popular that they sometimes cannot be shipped in time. Practicing reduced pesticide cultivation that is significantly stricter than the prefectural standards. At that time, all 38 members of the department were farmers who were certified as eco-farmers. Good soil is essential for good agricultural products. In collaboration with the “Green Gaia Experimental Plant” constructed by Tsuno Town, Koyu District, etc., the fungal fertilizer made from household garbage produced here will enrich the soil in a way that makes it unrecognizable, and the local community will grow. Environmental recycling type cultivation that returns garbage to the soil is also realized. Green Gaia, which Tsuno Town has been experimenting with since 2000, is a processing plant that utilizes fermented raw garbage to create soil. Approximately 400 kg of raw garbage per day, which is transported from specific businesses such as supermarkets, is fermented for half a day. It is used in two ways: applying it directly to farmland as a soil improver, and mixing it with livestock manure to make fully matured compost. When they return to the soil, the field is covered with pure white mycelium in about 6 days. It’s called fermentation with the soil, and it seems that the use of pesticides and chemical fertilizers will inevitably decrease because the roots of the crops grow a lot. JA’s tomatoes and cucumbers, as well as the grapes that make Tsuno wine, are also grown using this method. Good-tasting crops will become the town’s brand, and combustible waste will be reduced. In the future, it is expected that awareness of resource recycling will increase, such as promoting the use of this technology by farmers.
We strive to reduce pesticide use through thorough cultivation management, such as the use of insect nets, insect repellent sheets, and the use of natural pesticides. In addition, the food development laboratory of Keizairen conducts regular inspections of residual pesticides to check whether pest control is appropriate. Participate in the ODD movement (appropriate application of organic matter, deep cultivation, soil diagnosis). Do not apply excessive fertilizers, and apply appropriate fertilizers necessary for the growth and harvesting of crops.
The terrain consists of mostly flat plains and mountainous areas facing Mt. Osuzu. In addition, the temperature is warm throughout the year with an average annual temperature of 17.8°C, and many agricultural products are produced in the jurisdiction due to the natural conditions suitable for agriculture.
