となっている。2. Description of the Related Art Rice husk is produced as a by-product in the production of crops together with rice straw, etc., but the rice husk itself has poor fermentability, and also has poor digestibility when consumed by livestock and the like. For this reason, it was difficult to use as fertilizer and feed as rice straw. Therefore, some of them have been used as they are or burned (carbonized) and used as a base material for culture soil for raising seedlings or cultivating plants, or carbonized and recycled as a snow melting agent. Many have been disposed of or incinerated. In recent years, as an effective use of rice husks and the like, it has been proposed to dry distill rice husks and the like and use them as a vinegar solution as a plant growth promoter or an aid for promoting the growth of agricultural crops (JP-A-7-216362, JP-A-7-216362). 5-2394
No. 67). However, it is necessary to convert rice husks to vinegar liquefaction in order to utilize them, and the treatment for this purpose is not simple, so that the effective utilization of these by-products as resources cannot be effectively promoted. On the other hand, in recent years, the demand for soil for nursery boxes and plant cultivation in rice cultivation has been increasing. Soil supply is a problem. Therefore, as a substitute for natural soil used for these seedling and plant cultivation,
Providing an alternative soil with effective physical properties and functions,
This is an important issue for raising seedlings and plants in future agriculture.
