Description of the Related Art As is well known, essential elements necessary for the growth of plants are classified into a large amount of 9 elements and a small amount of 7 elements according to the required amount. The above-mentioned large elements include nitrogen (N), phosphorus (P), potassium (K), carbon (C), oxygen (O), hydrogen (H), calcium (Ca), magnesium (Mg), and sulfur (S). And the trace elements are manganese (Mn), iron (Fe), copper (Cu), zinc (Zn),
Boron (B), molybdenum (Mo), and chlorine (Cl). Although these require different amounts, they are still essential elements. In other words, as is known from the minimum nutrient rate of Dobenik, even if it is a trace element, even if one of them is insufficient, it is said that the growth and yield of plants will not increase even if the other elements are supplied sufficiently or in excess. I have. These essential elements are supplied to the plant from various fertilizers, but in recent years, especially due to the fact that coarse organic materials such as compost have not been introduced, breeding disorders especially due to lack of trace elements frequently occur. There is a tendency.

And, assuming element deficiency in advance, if soluble fertilizer components or soluble fertilizer components are introduced prophylactically, these fertilizer components are slow-acting, and the effect is sustained. Also has the advantage that it is not necessary to apply fertilizer frequently because it is not easily washed away. However, if the plant suddenly develops a deficiency, it is necessary to apply a water-soluble fertilizer component. That is, the water-soluble fertilizer component is fast-acting and is most suitable for urgent applications as described above.

For example, a mixed solution having the composition shown in Table 1 generates a considerable amount of residue and cannot be sprayed as a water-soluble fertilizer.

Form stable soluble salts with acid, alkali, heat and pressure with each element as a trace element.

Itself and this E. coli. D. T. A. Since the produced soluble complex salt is expensive, it is economically problematic as a fertilizer to be applied to agricultural products. Therefore, there has been a demand for a production method capable of easily and inexpensively producing a liquid fertilizer in which a trace element is dissolved in water.
