Nitric Acid Calculator for Haifa Soluble™ DUO and Haifa Cal™ Absolute 

Proper pH management of your stock solution is essential for ensuring both nutrient solubility and long-term stability. Maintaining the right pH has a positive effect throughout the entire fertigation cycle. 
For optimal system performance – and to preserve the stability of commonly used chelates – it is recommended to keep the pH between 5.5 and 6.0.

Use this calculator to determine the exact amount of nitric acid required for your solution, based on the fertilizer you are using, the type and concentration of available acid, the water volume, and your water quality.Enter your crop and usage details to get calculation for efficient nutrition and fertilization planning.
