| The Sometimes Forgotten Secondary Nutrients Magnesium¡ªSulfur |
Two of nature's products ¡ªmagnesium and sulfur¡ª are very important in the industrial world. Magnesium, in its metallic form, is the lightest of all building or structural metals. Sulfur is just as important industrially. Its many uses range from its use in producing sulfuric acid to a component of protein building blocks.
In addition to being important commercially, calcium, sulfur and magnesium are also vital to plant and animal existence. They are three of the 16 essential plant nutrients.
