Nitric Acid

Nitric acid is used in the production of ammonium nitrate and calcium ammonium nitrate which find application as fertilizers. Ammonium nitrate is also used in the manufacturing of urea ammonium nitrate (UNA) used in fertilizer formulation.

With regard to agriculture use, nitric acid can be applied directly to irrigation water by pumps that are particularly resistant to acids. Given the exothermic reaction caused when it is dissolved in water in favours solubility of other solid fertilisers which, one the contrary, can produce a drop in temperature.

It is also used in the preparation of stock solution when the pH needs lowering. The vefetative period of the crop has table considered to avoid causing, nutritional disorders by applying the product at time when the plant do not required nitrogen.
