In this rural setting, minerals provide nutrients, such as nitrogen, phosphorus, potassium, and a host of micronutrients essential to maximize crop yields to ensure reliable food supplies. Various metals and other mineral materials are required to build the harvesters shown, in addition to the equipment needed to prepare the fields for and to plant these crops. Open spaces are ideal for wind farms, comprising myriad wind turbines that require numerous mineral materials for the actual structures as well as the infrastructure to transmit the electrical power produced to consumers across the nation.
