Rising Carbon Dioxide Levels Could Make Crops Less Nutritious

Nutrient levels in staple food crops may fall as carbon dioxide levels in the atmosphere continue to rise. Researchers grew wheat, rice, soybeans, corn, sorghum, and field peas in fields subjected to carbon dioxide concentrations anticipated on Earth by the middle of this century. In four out of the six crops, zinc and iron levels were found to be reduced. The wheat and rice also had a reduced protein content. Sorghum and corn alone were able to resist the effects of the elevated carbon dioxide levels. More...

Ironic, then, that those whose job it is to study such things are the sort of person with the knowledge and resources to be working on a solution.

Make every post as if it was the first one in the thread.

Micronutrients

Micronutrients are those elements essential for plant growth which are needed in only very small (micro) quantities . These elements are sometimes called minor elements or trace elements, but use of the term micronutrient is encouraged by the American Society of Agronomy and the Soil Science Society of America. The micronutrients are boron (B), copper (Cu), iron (Fe), chloride (Cl), manganese (Mn), molybdenum (Mo) and zinc (Zn). Recycling organic matter such as grass clippings and tree leaves is an excellent way of providing micronutrients (as well as macronutrients) to growing plants.
