a solution basis would also facilitate balancing alkalinity of an irrigation water source with the acidity of the fertilizer to develop an overall neutral pH response of the overall nutrient solution. However, the same equation could also be adapted

irrigated, V is the volume of the container in gallons, and L is the percent Ca 2+ in a DL source (21% is typical). For example, an irrigation water source with 50 mg·L −1 Ca 2+ , applied at a depth of 1 cm per day to a #3 (3 gal) container with 15 cm
