Micronutrient malnutrition affects the health and well being of 3 billion people globally. Identifying means to improve the micronutrient density in the edible portions of crops is an important way to combat nutrient deficiencies. By studying how plants obtain micronutrients from the soil, we can develop methods to enhance uptake. Although more research is necessary, important farming methods include micronutrient and biofertilizers, crop rotations, organic matter management, and irrigation water fortification.
