Avoiding apple sunscald/sunburn
A higher concentration of potassium in apples reduces the incidence of sunburn/sunscald. However, potassium needs to be in balance with calcium, as these two nutrients compete with each other and can lead to poor calcium content in fruits, resulting in storage problems and other disorders related to calcium deficiency.
By improving calcium content in the skin and pulp, cells are less liable to damage and subsequent breakdown, thereby avoiding sunscald damage in apples.
