The United Nations estimates that the world population will reach 10.9 billion by 2100, and the University of Washington estimates that it will peak in 2064 and reach 8.8 billion by 2100. In any case, the world population is expected to increase from the current level. Therefore, in order to control the contact opportunities mentioned above, it is necessary to increase food production per area (= efficient production of agricultural products), and we believe that we can make a contribution to this.<\/p>\n\n\n\n<p>\u3000Last year, Mr. Yoshiro Manabe was awarded the Nobel Prize for his \"global general circulation model\" developed in the 1960s.

In addition, emphasis has been placed on improving the quality and taste of rice by testing a small amount of primary fertilizer and an emphasis on ear fertilizer for Koshihikari rice, as well as a dedicated primary fertilizer and additional fertilizer for Koshihikari rice. In 1995, the Food Law was enacted and the liberalization of rice distribution began. Since 1999, in addition to variety and weather control tests, organic slow-release fertilizer tests have been conducted on Koshihikari rice, including a single-shot and partial application organic fertilizer system developed for Koshihikari, and a special rice cultivation test, with a stronger awareness of the consumer in terms of taste, safety, and security. In particular, in order to promote the branding of Hanasaki Fukui Agricultural Cooperative's rice, we worked on the development of an organic, one-shot, organic fertilizer and promoted it as part of the \"Urara Series.

In 2008, the amount of fertilizer applied to Koshihikari rice was 8 kg N\/10a for conventional fertilizer and 7 kg N\/10a for late-planting fertilizer, a decrease from the previous year.

In the Meiji and Taisho periods, the majority of varieties were local species such as Shirachinji and Oba. In the first half of the Showa period (1926-1989), Nohbayashi No. 1 and Fukui Ginbouzu became popular, followed by Nohbayashi No. 23, Hounenwase, Manryo, Nihonbare, and Koshihikari in the postwar period, and finally the current Hanaechizen, Koshihikari, Akisakari, and Ichihomare. During this period, the yield per 10a of paddy rice has remarkably improved.<\/p>\n\n\n\n<p>\u3000The testing issues have also shifted from fertilizer and variety testing to ensure yield, to the pursuit of good quality rice, good taste, and labor saving (one-shot fertilization method, direct seeding, etc.).<br>\u3000I am truly humbled by the efforts of our seniors who have devoted themselves to tireless research and hard work during this period, as well as the cooperation of related organizations.<\/p>\n\n\n\n<p>\u3000The current era is known as the \"Warring States Period\" of rice production, and all rice-producing regions have entered an era in which they are struggling to survive. Will the rice production in 2025 head toward an era of brand-name rice, low-cost commercial rice, and rice for export?<br>\u3000In addition, the world is facing a number of issues such as hunger caused by population growth, global warming, and reduction of carbon dioxide emissions, as well as diversifying market needs and development of low-cost materials.<\/p>\n\n\n\n<p>\u3000Currently, the government is working to promote the spread of smart farming technology and the Green Food System Strategy. Under these circumstances, I think it is more important than ever before for farms of farmers and farm management advisors to tackle issues that are more relevant to the field and contribute to raising farmers' income. I would like to back up Sakai Farm as a base for agricultural promotion that will be more useful to everyone than ever before.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-left\">reference data<\/h3>\n\n\n\n<p class=\"has-text-align-left\">\u25cf\u5742\u4e95\u8fb2\u5834\u306e80\u5e74\uff08JA\uff09<\/p>\n\n\n\n<p class=\"has-text-align-left\">\u25cf\u5742\u4e95\u8fb2\u5834100\u5e74\u53f2\uff08JA\uff09<\/p>\n\n\n\n<p class=\"has-text-align-left\">\u25cf\u798f\u4e95\u770c\u306b\u304a\u3051\u308b\u6c34\u7a32\u65b0\u54c1\u7a2e\u80b2\u6210\u4e8b\u696d\u306e\u7d4c\u904e\u3068\u305d\u306e\u6210\u679c\uff08\u798f\u4e95\u770c\uff09<\/p>\n\n\n\n<p class=\"has-text-align-left\">\u25cf\u8fb2\u696d\u8a66\u9a13\u5834100\u5e74\u53f2\uff08\u798f\u4e95\u770c\uff09<\/p>\n\n\n\n<p id=\"page3\">\u3000<\/p>\n\n\n\n<p>\u3000<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">No Soil - No. 8<br>\u3088\u3044\u571f\u306e\u6761\u4ef6\u3000\u5316\u5b66\u7684\u6027\u8cea\u2212\u305d\u306e\uff13<br>\u9069\u5ea6\u306b\u542b\u307e\u308c\u308b\u4f5c\u7269\u306e\u990a\u5206<\/h2>\n\n\n\n<p class=\"has-text-align-right\">Jcam Agri Co.<br>\u5317\u6d77\u9053\u652f\u5e97\u3000\u6280\u8853\u9867\u554f<br>\u677e\u4e2d\u3000\u7167\u592b<\/p>\n\n\n\n<p>\u3000Of the four conditions for good soil for crop production, we have discussed three so far.

The debate began in Germany in the 19th century, settling the debate about nutrients between Thea, who believed that nutrients were organic (carbon-containing substances), and Shupe, who believed that they were inorganic (also known as minerals. The debate between Theja, who claimed that nutrients are organic (substances containing carbon), and Sprenger and Liebig, who claimed that they are inorganic (substances that do not contain carbon).<\/p>\n\n\n\n<p>\u3000The theory that organic matter is a nutrient was strongly influenced by the \"vital energy theory\" that was prevalent throughout society at the time. According to the animate theory, organic matter was produced with the help of a unique life force that existed only in living plants and animals, and that organic matter could not be produced from inorganic matter that did not have life. This argument, however, lost its basis when Weller of Germany synthesized urea, an organic substance, from inorganic substances in 1828. Thus, the controversy was settled on the basis of Sprenger and Liebig's claim that inorganic substances are nutrients. However, the idea that organic substances are nutrients has not disappeared, but has been handed down in the spirit of organic agriculture to this day.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. moderate nutrient levels and soil diagnostic reference values<\/h3>\n\n\n\n<p>\u3000By the way, how much of these nutrients must be present in the soil in adequate amounts? Moreover, crop nutrients are not merely sufficient if they are present in the soil, but they serve as nutrients for crops only when they are present in a form that can be absorbed by the crop (this is called the availability form). Therefore, to determine whether nutrients are adequately present in the soil, it is necessary to know how much nutrients are available in the availability form. Unfortunately, this cannot be determined just by looking at the soil. It can only be determined by analysis. In other words, nothing can be known without soil diagnosis.<\/p>\n\n\n\n<p>\u3000Soil diagnosis here refers to a series of operations in which the soil is analyzed to determine the pH level and the amount of available nutrients in the soil, to determine whether the analysis results are adequate, and to provide specific measures based on the results. The standard to judge whether the condition of soluble nutrients is adequate or not based on the analysis results is the soil diagnostic standard value. In other words, the appropriate amount of nutrients as a condition for good soil is the amount of nutrients in the soil that falls within the range of the soil diagnostic standard value.<\/p>\n\n\n\n<p>\u3000The amount of nutrients required by crops varies greatly from crop to crop. They may also be affected by the climatic conditions of the region where the crop is grown. For this reason, there is no uniform standard value for soil diagnosis that is valid for all crops in the country. Please refer to the information published by the testing and research institutes in your area to find out the specific values of soil diagnosis standards.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. nutrient supplementation based on soil diagnosis results<\/h3>\n\n\n\n<p>\u3000If all nutrients are within the range of soil diagnostic standards, the soil is considered to have adequate nutrients. However, this does not mean that compost, chemical fertilizers, or other materials do not need to be applied to the soil.
