Water Management in Horticultural Crops (1+1)

Disadvantages of fertigation

1. Uneven nutrient distribution occurs when the irrigation system is faulty. It leads to over fertilization or leaching of nutrients when excess water is applied to crops.
2. Chemical reactions of fertilizer with calcium and magnesium, bicarbonates in water, which can lead to chemical clogging.
3. Suitable for readily soluble or liquid fertilizers. Phosphatic fertilizer and some micronutrients may precipitate in micro-irrigation system.
4. Corrosion resistant fertigation equipments are needed.
5. Potential chemical backflow into the water supply source.
