Importance of Key Nutrients
Potassium (K₂O):
- Regulates Osmosis: Maintains water balance within the plant, increasing resilience in difficult conditions.
- Supports Carbohydrate Transport: Helps transfer nutrients from leaves to storage areas in fruits, roots, and tubers.
- Boosts Disease Resistance: Strengthens plants against diseases, improving growth and fruit quality.
Sulfur (S):
- Protein Synthesis: Combines with nitrogen to form amino acids essential for protein building.
- Vitamin and growth regulators Formation: Plays a crucial role in synthesizing vitamins and plant growth regulators.
- Enhances Photosynthesis: Contributes to chlorophyll production and photosynthesis, aiding in growth and resistance.
