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.
Most nutrients that plants need are readily available when the pH of the soil solution ranges from 6.0 to 7.5. Below a pH of 6.0 (acid): Some nutrients such as nitrogen, phosphorus, and potassium are less available. Above a pH of 7.5 (very alkaline): Iron, manganese, and phosphorus are less available.
