Nutrients are classified into three sub-groups based on plant growth needs. These
are:
• Macro or primary nutrients: nitrogen (N), phosphorus (P), potassium (K)
• Major or secondary nutrients: calcium (Ca), magnesium (Mg) and sulphur (S)
• Micro nutrients or trace elements: chlorine (Cl), iron (Fe), manganese (Mn),
boron (B), selenium (Se), zinc (Zn), copper (Cu), molybdenum (Mo) etc.
Nitrogen (N), the main constituent of proteins, is essential for
growth and
development in plants. Supply of nitrogen determines a plant’s growth, vigour, colour
and yield.
Phosphorus (P) is vital for adequate root development and helps the plant resist
drought. Phosphorus is also important for plant growth and development, such as the
ripening of seed and fruit.
Potassium (K) is central to the translocation of photosynthates within plants, and for
high-yielding crops. Potassium helps improve crop resistance to lodging, disease and
drought.
In addition to the three primary nutrients, the secondary nutrients sulphur, magnesium
and calcium are required for optimum crop growth. Calcium is particularly important
for the yield, quality and storage capacity of high-value crops such as fruit and
vegetables.
