Essential Elements
ã
The 16 elements required by plants are obtained from the soil, water and air.
ã
Thirteen of these elements must be supplied by the soil.
ã
Six of the soil elements required by plants are needed in relatively large amounts and are usually added to the soil through fertilizer or lime. These are called macronutrients.
ã
The remaining 7 elements supplied by soil are required in very small amounts and are termed micronutrients.
