Japan is placing emphasis on the latest technology and methods in the agriculture sector. At a recently held Agri World Expo, various kinds of agricultural technologies and supplies were introduced. It attracted agricultural industry professionals from all over Japan and Asia. Sanshin Metal Working Co.Ltd. introduced multi-stage cultivation racks, which enable growers to harvest plenty of crop per unit area.
They use artificial LED lights and wave length in order to raise productivity. They also use a hydroponic system to produce crops.
"The hydroponic system enables the control of many things like water supply or absorption of nutrients. It means that we can make high-value-added vegetables. For example, we can make a vegetable which is rich in beta-carotene. If there is someone who can't eat too much kalium, we can make it low-kalium. The system can make that kind of functionally-rich vegetables," said Sanshin Metal Working Co., Ltd., Hiroyuki Arai.
