る。2. Description of the Related Art In recent years, the aging of farmers has progressed, and there is a demand for lighter soil for raising seedlings. Mountain soil is currently used as a soil for raising rice seedlings. However, environmental destruction is feared, and it is expected that it will be difficult to obtain mountain soil in the future. Therefore, there is a need to reduce the amount of soil used for raising seedlings or to reduce the weight of the cultivated soil without using it.

確保することが困難となっている。However, cultivation without using soil or cultivation with a small amount of mixed soil cannot obtain the cation exchange capacity (CEC) and pH buffering ability of the soil. And CEC is low.
For this reason, these soils make the crops more susceptible to the effects of fertilizer pH and salt concentration, and as the amount of fertilization increases, germination and rooting disorders occur, and the fertilization required for seedlings must be secured by fertilization at the time of sowing. Has become difficult.

It is complicated to perform the topdressing work, and there is a demand for a method of raising seedlings without topdressing.
