The details of embodiments of the present invention will be described below.
This invention provides powdered fertilizer and pulp shreds. Powdered fertilizer may be organic fertilizer or chemical fertilizer, but powdered fertilizer is prepared. Since a powdered fertilizer is a commercially available product, its size is generally about -2 m / m. On the other hand, since pulp sludge or papermaking sludge was used as the pulp strips, they generally contained 5% of water.
It contains about 5% by weight.

Next, it was extruded through a molding machine and molded into an appropriate form for post-treatment. Then, the molded product was subjected to a granulation step depending on the intended use to obtain pellets.

According to experiments conducted by the inventor, the size of the pellets is generally processed into granules or spheres having a size of about 1 to 30 mm, but it is not limited to granules or spheres. Alternatively, it may have a long and narrow columnar shape of about 10 mm, or may have a random shape of about 10 mm, and what is necessary is to function as a soil conditioner.

【0014】次いで、ドライヤーによりそのペレットを

Since the present invention has the above-mentioned structure, it has the following advantages. (1) Since the pulp particles contained in the soil conditioner have a high water retention capacity, even if the fertilizer is melted by rainfall, the molten component is retained in the pulp particles. Therefore, since the components of the fertilizer that have conventionally flown out in a short period due to rainfall are retained for a long period of time, a soil improving agent having high fertilizing properties can be obtained. (2) As a result of processing by supplying an alkaline component during the papermaking process, although it is a relatively small amount in the alkaline component contained in the pulp strip, since it is contained in calcium, it plays a role of a binder. Therefore, the powdered fertilizer and the pulp pieces are surely organically combined and do not separate, depending on the viscosity of the pulp pieces. (3) As a result of the pulp pieces being combined with the powdered fertilizer, the conventional powdered fertilizer has a high viscosity, and when it is stored in the popper and discharged from the lower opening, there is a problem that a so-called bridge does not occur and does not fall. However, as a result of combining the pulp pieces, the viscosity is reduced due to the granular or spherical shape, and the bridge does not occur.
