[Prior Art] Since the pH of soil suitable for growing crops varies depending on the type of crop, it is difficult to set the pH range of the soil, but in general, the pH of soil suitable for most crops is 5. It is estimated that it is between .5 and 6.5. If the pH of the soil is outside this range, even plants that prefer acidic soil will grow well if the soil pH is between 6.0 and 8.5, but will grow in acidic soil with a pH of 5 or less. does not grow.

sLumpy or granular quicklime fertilizer (Cab) obtained by smoking limestone at high temperature, and strong alkaline powder slaked lime fertilizer with a pl of about 12.5 obtained by reacting quicklime with water ( Ca(011)2)
These fertilizers are selected and used as appropriate depending on the acidity state of the target soil, but slaked lime fertilizer in particular is in powder form and has a high alkalinity, so it is widely used as a quick-acting acidity correction agent for strongly acidic soil. It is used.

However, since the particles of slaked lime fertilizer are extremely small and have a low specific gravity, they are often lost due to scattering during spraying, so it is necessary to replenish the lost amount before spraying in order to achieve the desired fertilizer effect. Not only is this an economic disadvantage, but it can also cause pollution because it is scattered in areas other than the desired location, and it can also adhere to the skin of workers and cause skin irritation, get into the eyes and mouth, etc. Users have long had a deep-rooted need to prevent slaked lime fertilizer from scattering because it can cause problems such as inflammation in mucous membranes.

When preparing slaked lime fertilizer using only the pulp powder, the amount of water added is 5 parts by weight per 100 parts by weight of pulp powder.
It is preferable to adjust the amount to 00 to 700 parts by weight. If the amount of water added is less than 500 parts by weight, the concentration of pulp powder will become high and it will be difficult to disperse, and if the amount of water added is less than 500 parts by weight,
If the amount exceeds fi parts, the concentration of pulp powder becomes low and the treatment effect decreases.

When preparing slaked lime fertilizer using a mixture of the pulp powder and the melamine resin aqueous solution, the mixing ratio of the pulp powder and the melamine resin aqueous solution varies depending on the melamine resin content in the melamine resin aqueous solution, so it cannot be generalized. Although it cannot be determined, usually 20 to 500 parts by weight of the melamine resin aqueous liquid per 100 parts by weight of pulp powder, and <20 to 500 parts by weight of the melamine resin aqueous liquid.
The amount is preferably 300 parts by weight. If the amount of the melamine resin aqueous liquid used is less than 20 parts by weight, the relative amount to the pulp powder will be small and it will not be possible to disperse and mix it well, and it will become a medium for adhering the pulp powder to the slaked lime powder particles or pulp powder. The effectiveness of this decreases. Moreover, if the amount exceeds 500 parts by weight, even if the dispersibility is satisfied, the effect of increasing the amount will not be recognized, and an excess of the melamine resin aqueous liquid will adhere to the walls of the container, resulting in an economic disadvantage.

The amount of water added to the mixture of pulp powder and aqueous melamine resin liquid is preferably adjusted to 500 to 700 parts by weight per 100 parts by weight of the aqueous melamine resin liquid. If the amount of water added is less than 500 parts by weight, the concentration of the melamine resin will be high, the viscosity of the liquid will be high, it will be difficult to penetrate into the slaked lime, and it will be economically expensive.

Moreover, if it exceeds 700 parts by weight, the amount of melamine resin relative to slaked lime becomes relatively small, and the treatment effect decreases.

Note that the water used is not particularly limited in the present invention, and for example, tap water, well water, etc. can be used. An example of a method for adding water is a method of spraying water onto the pulp powder alone or a mixture of the pulp powder and an aqueous melamine resin liquid while stirring the pulp powder.

As the slaked lime powder, a commonly used powder mainly composed of calcium hydroxide obtained by pouring water into quicklime and digesting it can be used as is.

Furthermore, the slaked lime fertilizer of the present invention can be changed by adding the water-added pulp powder alone or a mixture thereof and a melamine resin aqueous liquid to the slaked lime particles. The amount of the mixture with the resin aqueous liquid added is 0.1 to 5 parts by weight in terms of the amount of pulp powder before dilution or the mixture of it and the melamine resin aqueous liquid per 100 parts by weight of lime particles, where <0. 5~
Preferably it is 1.0 parts by weight. If the amount added is less than 0.1 parts by weight, the resulting slaked lime fertilizer will easily scatter, and if it exceeds 5 parts by weight, it will become expensive and the proportion of slaked lime powder, which is the main component of the slaked lime fertilizer, will decrease. It becomes smaller and less effective as a fertilizer.

The mixing of the water-added pulp powder alone or a mixture thereof with the melamine resin aqueous liquid and the slaked lime powder is carried out by, for example, a mixing means such as a roll, a Banbury mixer, or a kneader. A mixture with an aqueous liquid is applied to the slaked lime powder.

In carrying out the method of the present invention, pulp powder alone or a mixture of pulp powder and a melamine resin aqueous liquid is added to the slaked lime powder while stirring the slaked lime powder. At this time, the melamine resin aqueous liquid is, for example, sprayed. It is also a preferred embodiment to mix and stir the compound by adding pulp powder and making the compound on the spot.

Thus, the slaked lime fertilizer of the present invention, which is composed of slaked lime powder and pulp powder alone or a mixture of them and an aqueous melamine resin liquid,
The anti-scattering effect is achieved through the following process.

The particles of slaked lime powder are negatively charged, and when a positively charged aqueous melamine resin liquid is added to the slaked lime powder, the melamine resin aqueous liquid adheres to the surface of the slaked lime particles. If pulp powder is added at the same time, the pulp powder is negatively charged, and the slaked lime powder particles are mixed with other slaked lime powder particles and/or pulp powder using the melamine resin aqueous liquid attached to the surface as a medium. adhere to. Note that water is preferably added to the melamine resin aqueous liquid before adding it to the slaked lime powder. This treatment causes the melamine resin aqueous liquid to adhere to the particles of slaked lime powder.

As a result of the above, the weight of slaked lime powder particles to which pulp powder alone or a mixture of pulp powder and melamine resin aqueous liquid is attached is:
The weight of the particles is larger than that of the slaked lime powder alone, and the light aggregation caused by adhesion of the slaked lime powder to the entangled pulp powder suppresses scattering during spraying. In addition,
Even if the weight of individual particles of slaked lime fertilizer increases, the bulk specific gravity of slaked lime fertilizer becomes lighter due to the voids created by the entanglement of pulp powder.

According to the method for producing slaked lime fertilizer of the present invention, when pulp powder alone or a mixture of it and an aqueous melamine resin solution is added to slaked lime powder and mixed and stirred, pulp powder alone or a mixture of it and an aqueous melamine resin solution are added within a few minutes. The mixture of slaked lime and slaked lime powder adhere to each other, resulting in slight agglomeration.
