Grown in mid-air — vertical smart vegetables to feed Chinese millions

Farmers in the Chinese city of Lishui, Zhejiang Province, have developed smart farms which allow vegetables to grow without soil. «The development of 3D agriculture is based on the geographical structure of Lishui», a mountainous area, said agricultural engineer Weiyang Lin who runs the project. «We employ the column to realise the planting pattern with less land and higher yields, which is... Еще six times that of ordinary farming.» Plants are provided with all nutrient solutions through an intelligent control system. A shorter growing season and a ban on pesticides also make smart farms more environmentally friendly. Chinese consume a daily average of 276 grams (9.7 ounces) of vegetables, according to the National Institute for Nutrition and Health, and farming methods need to adapt to a rapidly growing population.
