We have focused our attention on the behavior of certain ions, especially iron ion in water or interactions of water molecules with them. Since 1984, Akatsuka Garden Company has continued research on various solutions to not only accelerate plant growth, but also activate physiological functions of plants. Based on this research, we have developed FFC materials such as FFC-Ceramics (a water improvement device), FFC-Ace (a soil conditioner), and others. In addition, many agricultural producers in Japan have been utilizing FFC materials to rejuvenate plants and increase profits. Those producers have also explored many other original methods for using FFC materials, and consequently found good ways to fit them into their actual production sites. As a result, they have obtained many advantages over the years of use, such as, productivity enhancement, cost reduction, decreased amount of agricultural chemicals required, and others. In addition, it is reported that FFC-Ace enhances the growth of plants under laboratory conditions, and improves disease resistance, and drought and salt stress tolerance of plants (Ichikawa et al., 2013; Fujita et al., 2010; Hasegawa et al., 2006; Konkol et al., 2012; Shiraishi et al., 2010; Toyoda et al., 2010). In this paper, we will report a part of the results on the effectiveness of FFC-Ace on wine grape vines under field conditions. Yamanashi Prefecture is Japan’s top producer of grapes. However, the high quality grape berries for brewing are not cultivated easily in the cultivation environment of Japan (Asai, 1993; Nakayama, 1993). Therefore, we started a study on the promotion of the growth of ‘Chardonnay’ grape vines and quality improvement of the berries by using the FFC materials. In addition, we also examined an additional wine grape, Vitis vinifera ‘Koshu’. ‘Koshu’ grapes are widely cultivated in central Japan, particularly Yamanashi Prefecture. ‘Koshu’ is an indigenous grape cultivar that is used to produce Koshu wine, which is a special product of Yamanashi Prefecture.
