Generally water alkalinity to clot the dripper nozzle due to salt formation. So bring down the irrigation water pH to 5.5 to 6.5 may useful for prevent for salt formation as well as crop improvement. Please suggest
I am aware of those who use nitric or phosphoric acid, the N and P being more beneficial to plants than S.
Dear sir, thank you for your information my ultimate aim is to reduce scale formation in the drip irrigation nozzle as well as improving nutrient uptake without any plant damage by using sulfuric acid. Is it possible?

The answer to your question depends on the nature of your irrigation system (materials and their compatibility) and how tolerant your plants are to acids of different kinds.
They key is to titrate and adjust the pH of the water to close to neutral, slightly to the acid, to my mind, pH 5.5 seems quite strongly acid. I know that this works in some botanical gardens, but I am not familiar with the precise details. Typically the pH is adjusted for specific plants which do not tolerate alkali, calcium, and other minerals.
