Iodine deficiency in China goitre. This disease causes a swelling in the neck, where the thyroid glands are, leading to impaired cognitive abilities. The child population was about 20% saturated with the disease but continues to decrease with the new initiatives. Another common IDD prevalent in China is Kashin-Beck disease. A particular outbreak in Tibet was recorded as occurring from lack of iodine. Kashin-Beck is a bone deformity endemic. Iodine deficiency, hypothyroidism, and low serum concentrations of thyroxine-binding globulin were significantly related to Kashin–Beck disease. Iodine supplemented irrigation water in combination to iodized salt helps in reducing the neonatal and infant mortality rates. The
Micronutrient deficiency in the soil in which a plant grows. Micronutrients are distinguished from macronutrients (nitrogen, phosphorus, sulfur, potassium, calcium and magnesium) by the relatively low quantities needed by the plant. A number of elements are known to be needed in these small amounts for proper plant growth and development. Nutrient deficiencies in these areas can adversely affect plant growth and development. Some of the best known trace mineral deficiencies include: zinc deficiency, boron deficiency, iron deficiency, and manganese deficiency. Micronutrient deficiency Micronutrient deficiency or dietary deficiency is not enough of one or more of the micronutrients required for optimal plant or
