[Industrial Application Field] The present invention is applicable to plant nutrition, or
This relates to chemical fertilizers used to support the cultivation of plants. [Prior art and its problems] Fertilizer is an indispensable basic material for agriculture. Fertilizer ingredients, represented by nitrogen, phosphoric acid, and potassium, are made from salt powder and are used to produce several types of ingredients. Therefore, the amount to be blended is determined and mixed to produce the product. Powdered fertilizers suffer from problems such as segregation of ingredients during distribution after manufacture, caking due to moisture absorption, and scattering during fertilizer application. is used under the name. However, although chemical fertilizers solve the problems of component segregation and scattering during fertilizer application, they still have problems with caking. Consolidation of chemical fertilizers occurs when new salt crystals are formed between the grains during distribution and storage using water as a medium, and this, together with the stacking pressure, connects the grains. Fertilizer becomes in a state similar to the rock formations found in sweets, making it impossible to apply fertilizer. The moisture that causes caking is the humidity of the outside air that the grains are in contact with, and the moisture that is said to be around 1% contained in the chemical fertilizer itself.The outside air is the moisture that exists in the air inside the packaged chemical fertilizer. It is an atmosphere that makes you feel comfortable. To prevent caking, use fine powder with a large specific surface area such as silica flour or diatomaceous earth after granulation and drying.
Most of the problems have been solved by attaching about 0.1 to 1.0% to the surface of the chemical fertilizer, like rice cake flour. However, among the many chemical fertilizer formulations that exist, some, such as urea, dissolve on the surface even in the presence of a small amount of moisture, forming crystals that lead to caking, and the above-mentioned caking prevention method The current situation is that the method is ineffective and problems still remain. [Means for solving the problem] As mentioned above, the causes of caking are the humidity of the outside air and the moisture held by the chemical fertilizer itself, but as a result of intensive research, the inventors have found that the humidity of the outside air is They found that the absolute amount of water is so small that it can be ignored, and that the water held in the fertilizer itself is the biggest cause. That is, the granulated fertilizer is dried to a moisture content of around 1% and packed into bags, but naturally the surface is highly dry and has a low moisture content, and the inside is less dry and has a high moisture content. Afterwards, during distribution and storage, moisture begins to move from the center of high concentration to the surface of low concentration, and what comes to the surface evaporates during the day when the temperature is high, leaving the empty space inside the bag.
exists as humidity. At night, when the temperature drops, dew condenses and becomes water, which re-attaches to the surface of the fertilizer and begins to dissolve. By repeating this process, crystals precipitate and grains solidify. Anti-caking agents such as silica flower and diatomaceous earth sprinkled on the surface can prevent water evaporation and re-adhesion of condensed water to the fertilizer surface to some extent, but their water retention is poor, so if there is a large amount of water to be transferred. Alternatively, in the case of fertilizer components that have a high reaction rate with water, they may not be able to react sufficiently and crystals may form, causing problems with caking. The inventors investigated the cause of caking, and as a result of intensive research on countermeasures, they found that by dotting the inside of the grains of chemical fertilizer with holmite mineral powder, which is porous and has excellent water retention. It has been found that caking can be almost completely prevented. The chemical fertilizer of the present invention is made by mixing 1.0 to 15.0% of formite mineral powder with raw material powder and granulating it while adding water. It would be even better if you sprinkled with an anti-caking agent, and conventional chemical fertilizers,
Caking prevention is achieved by externally adding an anti-caking agent, and the present invention is characterized in that it is an internal addition and a combination of internal and external additions. That is, the present invention significantly improves the caking resistance by adding 1.0 to 15.0% by weight of formite-based mineral powder to the chemical fertilizer, and the second invention includes the first invention containing 8.0% binder. Contain the following,
The aim is to improve the granulation yield in the granulation process. In the third invention, 0.1 to 1.0% of an anti-caking agent such as silica flower or diatomaceous earth is externally added to the chemical fertilizers of the first invention and the second invention, and the mixture is allowed to adhere to the surface of the chemical fertilizer. The caking resistance of the chemical fertilizer of the invention is further improved. Note that if the holmite mineral is less than 1.0%, the effect of preventing caking is small, so the lower limit is preferably set to 1.0%. In addition, if the content exceeds 15.0%, the viscosity will increase and the fluidity during the granulation process will be inhibited.
Since the granulation yield decreases, it is preferable to set the upper limit to 15.0%. In addition, if the binder content exceeds 8.0%, the viscosity will increase, inhibiting the fluidity during the granulation process and significantly reducing the yield, so the upper limit should be avoided.
A good value is 8.0%. Furthermore, silica flour and diatomaceous earth are used as externally added anti-caking agents.
If it is less than 0.1%, the effect of preventing caking will be small, and if it exceeds 1.0%, the effect will be saturated, so it is preferable to set the upper limit to 1.0%. [Function] The present invention uses powder with a very large specific surface area, that is, sepiolite, which is collectively called holmite mineral,
By uniformly dotting attapulgiaite powder inside the chemical fertilizer, water is adsorbed and captured as it moves from the center, where the water concentration is high, to the surface, where the water concentration is low, and prevents water from coming out to the surface. . As a result, we succeeded in obtaining a chemical fertilizer in which less water evaporates into the air inside the bag, and therefore less water condenses and redeposit on the fertilizer surface, and the possibility of caking is extremely low. The holmite mineral used has a fibrous crystal structure, with countless pores of 10 Å to 300 Å distributed within the crystal, and its specific surface area is 300 to 350 m 2 /g.
It is said to have the largest specific surface area among natural mineral products. In addition, because it has many hydroxyl groups on the surface of the pores, it has excellent ability to capture moisture, and has a
It remains in chemical fertilizers because it has a water retention capacity of 1%.
It has sufficient water retention ability to fix around 30% of water. Example 1 The formulation of the chemical fertilizer used is shown in Table 1. As the holmite mineral, sepiolite from Nevada, USA was used.

It can be clearly seen that in both Examples 1 and 2, those containing sepiolite or attapulgite were better in preventing caking than conventional products. In particular, it has been shown that when an anti-caking agent such as silica flour is added externally to a product that has internally added sepiolite or attapulgite, caking is less likely to occur even under severe conditions, an effect that cannot be obtained with conventional technology. demonstrate.
