When and how fertilizers are applied to the olive tree?

Fertilizers should be applied at the base of the plant at a certain distance from the trunk. The farm should be immediately watered after fertilizer application. Foliar spraying of fertilizers is only done during emergencies or deficiencies. No fertilizer should be applied to the trees during winter (after august till march) because the trees does not grow during this period. Most of the fertilizer is applied during the growing season.
