For the exchange of nitrates and other mineral ions to occur between the root hair cell and the soil, the root hair cell needs a higher concentration of mineral ions and nitrates than the soil so that active transport can happen from the soil to the root hair cell. Please can someone explain how and why the root hair initially has more nitrate ions than the soil and what the point of absorbing these minerals is if the root hair cell already has more?

Sorry if this questions is worded badly or some of the information is wrong.
