Olive Grove Fertilization

In Brief…

The seminars on Olive grove fertilization aim to optimize production and also to avoid unnecessary fertilization that increases production cost and may harm the soil and the environment.
The lack of knowledge on modern methods among agronomists, but mainly among producers often leads to unnecessary fertilization or underestimation of fertilization needs of the orchard, leading to repeated loss of significant parts of production.
The seminars consist of two parts, the first, concerning traditional chemical fertilization and the second, concerning organic fertilization.

Conventional Olive grove fertilization

Introduction: Installation of new olive plantations – Selection of variety to plant.
Trees from cuttings or grafted?
What is organic matter and why it has an important role in olive fertilization.
Soil and leaves analysis- procedure.
Types of fertilizers. Selection criteria.
Modern spray- fertilization practices and their efficiency.
Fertilization to increase fruit set.
Fertilization to increase oil content of olives.
Improvement of olive oil quality (aromas, phenolic content) through fertilization.


Fertilization of organic olive groves

Why “organic” fertilization, how to do it, what is the expected benefit?
Organic fertilization: what is it, where and why it is applied, what are the basic techniques, what are the main differences from conventional fertilizers, the legal and regulatory framework, costing and evaluation of organic fertilization.
What is the outlook of organic olives and olive oil production, what is the interaction with the other cultivation practices (plant protection, pruning, and irrigation) and to what extent the quality and the cost of the product are affected.
