Proper fertilization is one of the most decisive factors for high productivity and good health of the olive tree. A well-nourished tree not only gives a stable and high quality production, but is also more resistant to adverse conditions such as droughts and diseases.

The essential nutrients of the olive
The olive tree, like all plants, needs specific nutrients to grow and perform at its best. The most important of these are:
- Nitrogen (N): Helps new vegetation to grow and contributes to the formation of fruits. If missing, leaves turn yellow and production is reduced.
- Phosphorus (P): essential for root system development and fruiting.
- Potassium (K): improves the quality and size of the fruit and increases the hardiness of the tree.
- Magnesium (Mg): important for photosynthesis and the general health of the tree.
- Boron (B): helps in flowering and fruit setting. If there is a deficiency, it can cause flower and fruit drop.
When and how is fertilisation applied?
Fertilization of the olive tree must be done at a strategic time so that the tree has all the necessary nutrients at the most critical phases of its growth:
- Late winter – early spring: This period is the most important, as the tree starts its intense activity with the development of new leaves and flowering later on. This is where a balanced fertilisation with emphasis on nitrogen is needed.
- Summer (if needed): In dry areas or in potassium-poor soils, a potassium booster may be needed.Also nitrogen and boron for good nutrition of the fruit.
What fertiliser should I choose?
The choice of the right fertilizer depends on the age of the tree, soil conditions and the growth phase. A complete fertilizer specifically designed for olives is ELEONES 22-5-11 + 2MgO + 0.3B, which combines all the basic elements needed by the olive tree.
This fertilizer contains:
- Nitrogen (22%) for vigorous germination and growth.
- Phosphorus (5%) for strong roots and flowering.
- Potassium (11%) for large and quality fruits.
- Magnesium (2%) for green, healthy leaves.
- Boron (0.3%) for better fruiting and less flower drop.
Doses and method of application
The dose of fertilizer depends on the age and condition of the tree:
- Young trees: 500-800 grams per tree, scattered around the root.
- Productive trees: 2-3 kg per tree, in a circle at crown height.
It is applied in dry soil, followed by irrigation to allow the nutrients to be absorbed by the roots.
By choosing the right fertilizer and applying it at the right time, we ensure a healthy, productive crop with high quality fruit and reduced occurrence of the phenomenon of stunting.
