A composition of ferrous compounds is provided to produce a ferrous aqueous solution for repressing precipitation although a composition is diluted and stored at higher temperature than normal temperature, and profitable for both animals and plants by adding nicotinic acid. A composition of ferrous compounds for effectively preventing iron from being settled in an aqueous solution containing iron sulfate is produced by making a solution by dissolving the iron sulfate in the water and adding L-ascorbic acid, and then adding nicotinic acid and stirring the solution and nicotinic acid at normal temperature. The L-ascorbic acid and nicotinic acid are added to an iron sulfate aqueous solution as an anti-precipitating agent. In particular, the nicotinic acid of 10~200wt.% is added for L-ascorbic acid. |
