Description of the project

DESCRIPTION
Phosphoric acid is a highly corrosive acid consisting of hydrogen and phosphate ions. Phosphoric acid provides plant nutrients in the form of phosphate.

RECOMMENDATION
For adjusting the pH of nutrient solutions for irrigation:
The dose depends on the alkalinity of the water, i.e. its hydrogen carbonate ion content. Do a raw water analysis to know the alkalinity.

0.125 l Phosphoric Acid 75% neutralizes an alkalinity of 100 mg/l in 1000 l of irrigation water. Remember to leave an alkalinity of 50 mg/l in the water to maintain some buffering capacity in the water.

Example: Your water has an alkalinity of 180 mg/l. You want to neutralize 130 mg/l (and keep 50 mg/l). You need 0.125 x 130/100 = 0.16 liters of nitric acid per 1000 liters of irrigation water. This corresponds to 1.6 liters per 100 liters of stock solution if the dilution to working solution is 1:100.

Phosphoric acid can be mixed with other fertilizers, but be careful not to allow the pH to become too low in stock solution vessels containing chelated micronutrients. Avoid mixing phosphoric acid in the same stock solution tank as calcium nitrate (risk of precipitation of calcium phosphate).

We recommend an alkalinity water analysis to check that the alkalinity of the finished nutrient solution is correct. It is also important to analyze recirculated nutrient solutions to be able to adjust both plant nutrition and alkalinity before the nutrient solution goes back to the crop again.
