The concentration of mineral nutrient elements is higher inside the root-hairs than in the surrounding soil. How do roots take them in from the soil?

As the concentration of mineral nutrient elements is higher inside the root-hairs than in the surrounding soil the roots takes up the minerals by the active transport system. In this process transport of the mineral, ions take place from the region of lower concentration to the region of higher concentration using energy (ATP) supplied by the cell membrane.
