Characteristics of fertilizers for fertigation

The success of fertigation depends primarily on the characteristics of the fertilizers used.

1. Must be completely soluble in water (< 0.02% insoluble in water) and have quick dissolution in water with minimum content of conditioners.
2. Must not react with dissolved elements in water especially calcium and magnesium salts.
3. High nutrient content in the saturated solution must not get leached down easily from the soil.
4. Should not change the pH of water leading to precipitation and clogging
5. Should avoid corrosion of the system.
6. Should be safer for field use and for mixing with other chemicals.
