To develop a fertilizer program, begin with testing the alkalinity of your water. Alkalinity is not a measure of ph, but a measure of the bicarbonates and carbonates present in the water and is expressed in parts per million (ppm) calcium carbonate. Essentially, alkalinity is a measure of the quantity of “limestone” dissolved in the water.
