Crop Nutrition and Citrus Peel Blemishes

Ensuring a good calcium and potassium supply helps increase peel strength and resistance to blemishes such as pitting.

The role of calcium in improving skin cell wall strength has been confirmed in Spanish trials. Treated mandarins had greater fruit firmness during ripening on the tree, making them less susceptible to puncturing during harvest, transport and storage. In this trial, this improvement lasted at least 2 months.
