Mineral
Definition: mineral
mineral: an inorganic solid substance with a characteristic chemical composition that occurs naturally. The names of many minerals end with the suffix -ite. The most important minerals required by the body are: calcium (found in cheese, milk and green vegetables) which helps the growth of bones and encourages blood clotting; iron (found in bread and liver) which helps produce red blood cells; phosphorus (found in bread and fish) which helps in the growth of bones and the metabolism of fats; and iodine (found in fish) which is essential to the functioning of the thyroid gland. Understanding the role of minerals in soil and livestock nutrition can help farmers prevent deficiencies and ensure better crop and animal health and productivity.
