A proper calcium intake is a key to normal root system development, a healthy fruit set, and quality fruit development at the same time as it stimulates photosynthesis and makes nitrogen use more efficient. So we can describe calcium as an element of primary importance.

Some Ca-related physiological disorders include the death of growing points, premature shedding of blossoms and buds, tip burn, blossom end rot (BER), and bitter pit to name a few. Other symptoms of calcium deficiency affect fruit quality and firmness: the taste and shelf-life of fruits such as cantaloupes and tomatoes can be reduced significantly and perhaps that is the most economically impacting aspect of this issue.
