Fertigation is the technique of applying water-soluble fertilizers through the irrigation system — drip, sprinkler, or mini-sprinkler. This delivers nutrients precisely to the root zone when plants need them most, improving uptake efficiency by 30–40% compared to broadcast application.

| Pre-Flowering | MAP 12:61:00 | 3–4 | 2× per week |
| Flowering / Fruit Set | Calcium Nitrate 15.5-0-0 | 4–5 | Weekly |
| Fruit Development | NPK 13:00:45 or SOP | 5–8 | Weekly |

Electrical Conductivity (EC) is the key measure of nutrient solution strength. Target EC 1.5–3.5 mS/cm for most vegetable and fruit crops. High EC (>4 mS/cm) causes osmotic stress and leaf burn. Always measure source water EC before adding fertilizers.
