Minerals for Plants, Animals and Man
Via del.icio.us (scifi) and the Alberta government, Minerals for Plants, Animals and Man:
Twenty five elements are recognized as essential components of plants, animals and man. Because these elements are considered essential to life, they could be called “bioessential.” A few others, such as cobalt and the rare earth elements, could be included, but information on their roles is less exact. Carbon ©, Nitrogen (N), Oxygen (O) and Hydrogen (H) are primarily derived from air and water and are not discussed; the other 21 elements, listed in alphabetical order, occur as minerals in the soil.
