佐渡海洋深層水を水田で葉面撒布することで、カドミウム(Cd)が土壌や米粒に蓄積される事は無く、稲の生長・穂丈の強化と米の甘味増加が見られた。プランターで1/20希釈深層水又は1mM塩化亜鉛水溶液を用いて栽培すると、米の収量が増加し、米粒中の亜鉛含量が増加し、亜鉛強化米として健康に役立つ。また海洋深層水の利活用の一翼となる。

Deep-sea water pumped up from 350 meters deep off of Sado island has been utilized for drinking, preparation of food and therapeutic spas for years but other applications can now be expected. One of them is use in agriculture. In this paper, we would like to suggest the use of deep-sea water for growing rice and using zinc solution to fortify rice grains to create higher nutritional value. In use of mineral rich deep-sea water, the absence of cadmium accumulation in both soil and plants should be proven. Our study indicated the absence of cadmium accumulation but a stimulation of growth and stiffness of plants are evident. A stimulating effects and in increase of zinc content from deep-sea water have been observed in several investigations supporting this effect on rice. The taste of rice grown with deep-sea water and zinc solution is as good as ordinal commercially available rice for both young and old. Zinc content in our soil is rather low and fortification with zinc in food materials is recommended for health, especially for some patients with anemia. Zinc chloride for Sado deep-sea water to rice plants via irrigation may contribute to regional nutrition and health promotion. Also, this deep-sea water can be used to nurture rice paddies, when small animals proliferate and these can be insure to feed Toki birds (Nipponia nipon) in the wild. In laboratory experiments, we have demonstrated that the use of both diluted deep-sea water in place of desalinated water and zinc solution for irrigation of rice paddies increase the harvest of rice and fortify rice grain fwith zinc without alterating of the taste. We will briefly discuss the function of zinc in foods.
