Primary macro nutrients:
- N: Nitrogen is the basic constituent of proteins, enzymes and chlorophyll, and is involved in all the major processes of plant development and yield formation. Nitrogen fertilisers include ammonia, urea, ammonium nitrate and ammonium sulphate.
- P: Phosphorus is essential for photosynthesis and other chemico-physiological processes.
- K: Potassium plays a vital part in carbohydrate and protein synthesis and increases plant’s tolerance against climate factors and disease.
Secondary macro nutrients
- Mg: Magnesium
- Ca: Calcium
- S: Sulphur
