（発明が解決しようとする問題点）
しかし、上述の貝化石を原料とする肥料は貝化
石が固形状若しくは砂状である。従つて粉末化し
ても植物への吸収が低いなどの欠点があり、貝化
石中に含まれるカルシウム分が完全に肥料と成り
得ないなどの難点がある。(Problems to be Solved by the Invention) However, in the above-mentioned fertilizer made from shellfish fossils, the shellfish fossils are solid or sand-like. Therefore, even if it is powdered, it has drawbacks such as low absorption into plants, and the calcium content contained in shellfish fossils cannot be completely used as fertilizer.
そこで、この発明は貝化石を原料としてポーラ
