impact of the phosphate fertilizer imports is significant because the country relies entirely on imports, and the need for efficient use of phosphate fertilizer was strongly recognized when the price of phosphate ore rose sharply. As a result, the possibility of fertilizer reduction based on soil diagnosis was studied on a nationwide scale. At the same time, studies were conducted on the variation of soluble phosphoric acid in soil. Here, we introduce a study by the authors (Nishida et al., 2018) on the relationship between temperature and changes in soluble phosphate in paddy soils under waterlogged conditions. This study was conducted at the Daisen Research Station, Tohoku Agricultural Research Center, National Agricultural Research Institute, Japan.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2.
