pH Acid is an acidifying fertilizer based on nitrogen, sulphur, and seaweeds (Sargassum, Laminaria), suitable for fertigation. It’s an important source of macronutrients and organic elements, enhancing its quality. This product allows a reduction of carbonates and bicarbonates content present in irrigation water, neutralizing them and so acidifying the solution. The composition of pH Acid and the right balance amongst its elements make this product a very effective means for fertilizing the plants suffering a physiological stress condition, also carrying out a biostimulant action.
