す。2. Description of the Related Art Various nutrient elements are necessary for a plant to grow, but these elements are not always sufficiently present in soil. For this reason, it is known that the deficiency of some elements may hinder the growth of plants. For example, nitrogen (N) is a component element of protein, and phosphorus (P) plays an important role not only in constituent elements of nucleic acids and phospholipids but also in energy metabolism and synthesis / decomposition of substances as fertilizers. In addition, potassium (K) has a physiological action of mass metabolism and mass transfer. Lack of these key components generally leads to poor plant growth. In addition, calcium is an important component of the plant and cells,
It also plays an important role in maintaining the balance of the metabolic system, but it has calcium deficiency symptoms and physiological disorders such as tomato butt rot, cabbage and cabbage core rot, apple bitter pit, strawberry Cause chip burn etc.

いのが現状である。[0003] For nitrogen, phosphorus and potassium deficiencies, fertilizers are applied to the soil. Also, in order to prevent physiological disorders due to calcium deficiency, many attempts have been made to apply inorganic calcium and the like to the soil and supply them from the roots. As a result, they flow down into the basement or react with fertilized fertilizer and become immobilized. Under the conditions described above, the fertilizer balance between the chemical fertilizer and the calcium component is deteriorated, and the fertilizer is often not sufficiently supplied to the plant. And even if absorbed from the roots of the plant,
Calcium is an element that is very difficult to transfer in plants, and often does not reach the site where physiological disorders actually occur. At present, it takes a considerable amount of time to arrive, and there is no immediate effect at present.

Also, spraying excessive fertilizer components such as N, P, K and calcium salts to increase the amount of absorption results in stress on plants, which results in phytotoxicity.
