Acid Choices for Reducing Water Alkalinity | PRO-MIX

Extra phosphorus will not ,harm, the crop, but it can lead to stretching and softer growth. If phosphoric ,acid, is used, consider using a fertilizer with no phosphorus, such as 17-0-17, 20-0-20, 25-0-25, etc. Sulfuric ,acid, provides sulfur in the form of sulfate, which is needed by plants and is often low in water sources and fertilizer programs.
