Water Management in Horticultural Crops (1+1)

Precautions to be taken during fertigation

1. Perfect design of irrigation system. Every emitting point must deliver the same volume of water.
   
2. The material used must be free from deposits or residues and must not cause corrosion of system.
   
3. Constant operating pressure to facilitate uniform mixing of water and fertilizers.
4. Selection of most appropriate fertilizer, injection system and crops for fertigation.
5. Fertilzer injection should not begin until all lines are filled with water and emitters are working.
6. Drip irrigation system should be allowed to its working pressure prior to fertilizer injection.
7. Fertilizers/pesticides/chlorine should not be injected at the same time.
