性の面で問題がある。2. Description of the Related Art A method for granulating a powdery or slurry-like substance is described in detail in a manual for granulation (Ohm). Granulation is generally carried out by mixing a substance to be granulated with a binder, kneading, and granulating by rolling, compressing, pressing or the like, and is usually performed by a granulator. However, for the purpose of effectively utilizing waste soil in the field of agriculture and horticulture, granulation using a granulator increases costs and has a problem in practicality.

る。On the other hand, a granulation method for gel encapsulation using sodium alginate as a binder is already known. The principle of this granulation method is to form a polyvalent metal salt of alginic acid by dispersing a powdery or slurry-like substance in an aqueous solution of sodium alginate and then dropping it into an aqueous solution containing polyvalent metal ions such as calcium ions. This is to form a spherical capsule having a solid film. However, this granulation method is also expensive and has a limited throughput.

利用されている。[0004] The soil used for granulation includes, for example, organic soil. The organic soil is a thick pile of dead moist plant remains, and is classified into low-grade peat soil mainly composed of reeds and sedges, medium-grade peat soil mainly composed of Numagayaya and Watasuge, and high-grade peat soil mainly composed of sphagnum. Is done. In high-grade peat soils in cold regions such as Siberia and Canada, decomposition of plant remains hardly progresses and plant tissues remain clearly, and dried peat soil is used in agricultural and horticultural fields as `` Peat Moss '' .

することはできない。[0005] On the other hand, organic soils in Japan are often decomposed in plant tissues, and are rich in fertilizer components. Therefore, effective use in the agricultural and horticultural fields is desired, but generally the water content is high. Due to poor drainage, it cannot be used without improving water permeability.
【０００６】従って、国内にある有機質土をピートモス
