Phosphorus ions (H2PO4- and HPO42-) are the only form in which plants can take up phosphorus. Similarly, nitrogen can be taken up by plants in the form of ammonium (NH4+) or nitrate (NO3-) ions. However, carbon and hydrogen are not essential elements for plant growth and they do not need to be taken up in any specific form.
