1 Carbon, hydrogen and oxygen, three of the essential plant nutrients, are taken up from the atmosphere and from water. The other essential nutrients come from the soil.  The major nutrients, or macronutrients, supplied by the soil are nitrogen, phosphorus, potassium, sulphur, magnesium and calcium.
The âsoil cationsâ essential for plant growth include ammonium, calcium, magnesium, and potassium. There are three additional âsoil cations,â which are not essential plant elements but affect soil pH. The additional âsoil cationsâ include sodium, aluminum and hydrogen.ptake of water and nutrients by roots. 1  Root hairs, along with the rest of the root surface, are the major sites of water and nutrient uptake. 2  Water moves into the root through osmosis and capillary action. 3  Soil water contains dissolved particles, such as plant nutrients.
