HORTICULTURE

Detailed explanation-1: -The higher the alkalinity, the more ‘’limestone” that is being applied, causing the pH of the growing medium to climb. To offset this pH rise, acids are injected into the irrigation water to neutralize some of the alkalinity and reduce the ‘’limestone” content in the water.

Detailed explanation-2: -Acid converts alkalinity into dissolved CO2 (carbonic acid), which lowers the pH of the water. Specifically, acid converts bicarbonate alkalinity into carbonic acid (H2CO3) by adding Hydrogen to it. Simplified, we think of it as acid ‘burns through’ alkalinity to reduce pH.

Detailed explanation-3: -Add vinegar to the water for an inexpensive fix. Measure 1 US tbsp (15 mL) of plain white vinegar and pour it into 1 US gal (3, 800 mL) of water. The natural acidity of the vinegar will help neutralize the alkalinity in the water, bringing a pH of 7.5-7.7 down to about 5.8-6.0.
