A new iron fertilizer for promotive plant growth

摘要

A mass production technology for FeO and technology to retard oxidation of the developed FeO in water and atmospheric environments were successfully developed based on Aichi Steel's special steel technology. In comparison with conventional FeO, which has the property of easily dissolving in water, the new FeO material developed by Aichi Steel (hereinafter referred to as developed FeO) resists oxidation in water for more than 1 year. Aichi Steel also successfully developed a technology for dissolving Fe~(2+) out of the developed FeO. The developed FeO consists of FeO as its main component, and also contains minerals such as Ca, Mg, Zn, etc. Based on these technologies, a new iron fertilizer using the developed FeO as its matrix was prepared and supplied to various plants. As a result, organ growth and increased contents of minerals, vitamins, polyphenols, and sugar were observed in many of the plants.
