Paddy rice fertilizers are categorized by application into coated nitrogen fertilizers, chemical compound fertilizers, compound fertilizers, fertilizers dedicated for whole rice seedling box application, and soil fertility fertilizers.<\/p>\n\n\n\n
A coated fertilizer made by coating nitrogenous fertilizers such as urea with a film material. <\/p>\n\n\n\n Unlike chemical fertilizers, these fertilizers are formulated with granular fertilizer. <\/p>\n\n\n\n Compound fertilizers are made by mixing fertilizer materials and reacting them with heat to form granules, each of which contains fertilizer components such as chisso, phosphoric acid, and potassium. <\/p>\n\n\n\n Seedling Box Makase\" is a coated fertilizer that minimizes leaching of fertilizer components during seedling growth, and is the only fertilizer that can be applied in contact with paddy rice roots. <\/p>\n\n\n\n Phosphorus Star is a soil-building fertilizer that can improve soil chemistry.
Representative products include LP Coat, M Coat, and Meister, as well as the new environmentally friendly J Coat.
The number of days of 80% elution at 25\u00b0C is shown numerically.
There are two types of leaching patterns: linear (L) type, which leaches continuously after fertilizer application, and sigmoid (S) type, which suppresses leaching for a certain period of time after fertilizer application.<\/strong><\/p>\n\n\n\ncompound fertilizer<\/strong><\/h3>\n\n\n\n
We combine coated urea, which allows for control of the elution period of the thio component, with other chemical fertilizers and trace components to provide the necessary amount of each component required for the crop, mainly the major components of thio, phosphoric acid, and potassium, in the required amount and at the required time, making it a so-called \"one-shot fertilizer.
There are various brands according to the ratio of ingredients contained and the elution period of coated urea. These are labor-saving fertilizers that can reduce the number of fertilizer applications by controlling the amount of fertilizer ingredients and elution period according to the soil and crop variety.<\/strong><\/p>\n\n\n\nBase fertilizer(for) supplementary fertilizer<\/strong><\/h2>\n\n\n\n
chemical fertilizer<\/h3>\n\n\n\n
There are phosphorous sulfuric acid systems and nitric acid systems containing nitric acidic chisso, depending on the chisso raw material, and NK chemical synthesis is available depending on the component.
In addition, \"IB Kasei\" and \"CDU Kasei,\" which contain nitrate inhibitors and slow-release nitrogen as raw materials for chemical fertilizers, are chemical fertilizers with a long-lasting effect of nitrogen.<\/strong><\/p>\n\n\n\nDedicated to whole seedling box fertilizer application<\/strong><\/h2>\n\n\n\n
Fertilizer exclusively for whole rice seedling box application<\/h3>\n\n\n\n
The \"N400\" has only chisso as a fertilizer component, while the \"NK301\" contains coated potassium.<\/strong><\/p>\n\n\n\nkeeping soil in good conditionuse<\/strong><\/h2>\n\n\n\n
soil fertilizer<\/h3>\n\n\n\n
In addition to \"Linstar 30,\" which contains 30% soluble phosphoric acid and 8% bitter soil, there is \"BM Linstar,\" which contains manganese and boron.
Kaykalin\" is a new type of soil fertilizer that combines \"Phosphorus Star\" with potassium silicate.
