*Based on irrigation rate of 20-30 m3/ha /day, and on the assumption that irrigation water contains at least 26 ppm of Mg, 50 ppm of Ca, and 30-40 ppm of S.

 

 

 

Injection rate: 5 liters of concentrated fertilizer solution from each tank should be injected per 1 m3 irrigation water.

Multi-K = Potassium nitrate (13% nitrogen as nitrate + 46% K2O)
Haifa MAP = Mono-ammonium Phosphate (12% nitrogen as ammonium + 61% P2O5)
Calcium nitrate (15.5% nitrogen as nitrate + 26.5% CaO).
Magnesium sulfate ( 32% magnesium as MgO + 18% sulfate as S).
