Trace elements play a key role in the nutrition of the olive tree, directly affecting the growth, productivity and quality of the olive fruit. Although required in small quantities, their deficiency can lead to serious food deficiencies and a reduction in yield.
Main trace elements and their role in the olive tree
- Boron (B):
○ Operation: It contributes to the development of cell walls, pollination and fruit binding. Boron sufficiency improves flowering and the quality of olive oil
○ Symptoms of deficiency: Deformation of leaves, reduced flowering and fruit set, necrotic spots on fruits.
- Zinc (Zn):
○ Operation: Important for auxin synthesis, shoot growth and bud differentiation.
○ Symptoms of deficiency: Microfoliation, brachyagenesis, chlorosis between the ribs of the leaves.
- Manganese (Mn):
○ Operation:Involed in photosynthesis and nitrogen metabolism.
○ Symptoms of deficiency: Chlorosis on young leaves, with the nerves remaining green.
Interfacial application of trace elements
Trans-water fertilization is an effective means for the immediate treatment of food deficiencies, as it allows the rapid absorption of nutrients by the leaves. The application of liquid chelated trace elements ensures high availability and absorption, helping to correct deficiencies immediately.
