Zinc Fertilizer: Address Food and Nutrition Security and Fertilizer Efficiency in China
China is one of the largest agricultural countries in the world, and has experienced very rapid growth in agricultural production in the last two decades following its economic reforms.It is a great challenge to use 9％ of the world arable area to meet the increasing demands of 1.3 billion people, about 22％ of the world”s population, for food, fiber and fuel.Fertilizer use in China has also been increased significantly to over 56 million tons in 2010, contributing greatly to the sustainable development of Chinese agriculture.However, the intensification of agricultural production per unit area, coupled with large amount of using macronutrient fertilizers, such as nitrogen (N), phosphate (P), and potassium (K), is causing zinc deficiency to spread rapidly throughout China.Recent research findings in China indicate, zinc deficiency is the most widespread micronutrient deficiency in China.Nearly 50％ of arable soils are low in plant available Zn, limiting further sustainable increases in agricultural production and improvements in human nutrition.
