Using isobutylidene diurea, which is a condensation product of urea and isobutyraldehyde, it is mixed with potassium fertilizer such as potassium chloride and other fertilizers as necessary, and granulated by moat with gypsum. This product is known as a compound fertilizer for top-dressing paddy fields, but when it is sprayed on paddy fields, as the water-soluble fertilizer components elute, some of the fertilizer components that are elutriated by the water are deposited near the water surface. The disadvantage is that it makes it easier to float.

It is a granular compound fertilizer made by mixing an aqueous nitrogen fertilizer, a potash fertilizer, and gypsum in water, which is a condensate, and granulating it, and then adding an alkali metal salt or an alkali metal salt of an alkylbenzenesulfonic acid to the granulate. .

加しながら転勤させて行うのがよい。As the gypsum, anhydrite, hemihydrate gypsum, and dihydrate gypsum can all be used. Industrially, it is advantageous to use gypsum produced as a by-product during phosphoric acid production (phosphoric acid-generated gypsum), or gypsum obtained as a product during flue gas desulfurization (flue gas desulfurization gypsum). The amount of gypsum to be used is preferably 2 to 15% by weight, preferably 5 to 1% by weight, based on the entire granular compound fertilizer. If the amount is too small, the hardness will not be sufficient and only granular compound fertilizer will be obtained that tends to float. On the other hand, if it is too large, the content of fertilizer components will be low, which is not preferable. Granulation is usually carried out by mixing the fertilizer components and gypsum as described above, using a drum-type or dish-type granulator, and transferring the mixture while adding water.

For use in paddy fields, it is generally on the 1.5 to 4.5 side.
In the present invention, the alkali metal salt or alkali metal salt of alkylbenzenesulfonic acid to be contained in the granular compound fertilizer includes benzenesulfonic acid having an alkyl group having 6 to 1 carbon atoms and preferably 10 to 14 carbon atoms, and sodium chloride. , salts with alkali metals such as potassium, or alkali metals such as calcium, magnesium, and barium, and a typical example is sodium dodecylbenzenesulfonate.

。In order to incorporate an alkali metal salt or an alkaline earth metal salt of alkylbenzenesulfonic acid into a granular composite fertilizer, it may be added at any stage from the production of the granular composite fertilizer to its use, for example, the fertilizer component before granulation. Alternatively, there are methods such as adding it to gypsum, adding it during granulation, or adding it to granules after granulation. It is preferable to add an aqueous solution of about 2 to 3% by weight of the metal salt or alkali metal salt during granulation or to the fertilizer component or gypsum before granulation.

％」は、それぞれ「重量部」および「重量％」を示す。If this amount is too small, the effect of preventing floating can no longer be expected. On the other hand, if there is too much, no special effect can be expected. In addition, when adding an alkali metal salt or alkali metal salt of alkylbenzenesulfonic acid during granulation or adding it to fertilizer components or gypsum before granulation, if the amount added is too large, granulation will occur. I don't like it to be difficult. The granular composite fertilizer of the present invention contains slow-release nitrogen fertilizer and potassium fertilizer and does not float in water, so it is particularly suitable as a fertilizer for top-dressing paddy fields. EXAMPLES Hereinafter, the present invention will be specifically explained with reference to examples, but the present invention is not limited to the following examples unless it exceeds the gist thereof. In addition, in the examples, "part" and "

32 parts of ammonium sulfate, 104 parts of urea, 242 parts of potassium chloride, and 8 parts of gypsum dihydrate (phosphate by-product) were mixed and charged into a dish-type granulator, and sodium dodecylbenzenesulfonate (manufactured by Lion Oil Co., Ltd.) was mixed. , Product name L-D
Transfer granulation was carried out at 55:00 for 6 minutes while spraying 15 parts of a 20% aqueous solution of #50) and 8 parts of water.

併記する。The results of measuring the hardness and floating rate in water of this granular composite fertilizer are shown in the table below. For comparison, the results obtained when sodium dodecylbenzenesulfonate was not added in the above example (Comparative Example 1) and when dihydrate gypsum was not used (Comparative Example 2) are also shown.

た。However, in the above table, the hardness indicates the average value of 2 hardness values measured using a Kiya type hardness meter for particles having a particle size of 2.4 to 2.8 ribs. In addition, the water surface flotation rate was determined by adding 25 μm of granular fertilizer to a 170×220×25-sided pad containing 600 μm of water and leaving it at room temperature for 1 hour and 6
After a period of time, those that floated to a depth of 5 skins below the water surface were collected, dried, and expressed as a percentage of the granular fertilizer provided.
