In the Italian olive growing landscape, tradition represents a fundamental value, but today it is no longer sufficient on its own to ensure economic and technical sustainability. Innovation therefore becomes a concrete necessity. A clear example of this evolution comes from the province of Rieti, where an olive grove has been redesigned according to modern, functional, and sustainable criteria.
The case analyzed concerns the
transition from a traditional system to the free, bush shaped vase inspired by
the Zaragoza principles, a solution capable of combining productivity, ease of
management, and adaptation to the current needs of olive growing.
Transforming
the Grove: From 6 × 6 to 6 × 3
The grove under observation
consists of approximately three-year-old Leccio del Corno trees, originally
planted with a traditional 6 × 6 meter spacing, typical of the “Policonic” vase
system.
The intervention involved
increasing planting density, shifting to a 6 × 3 meter spacing, with a new
structural setup based on the Zaragoza free vase system.
The main characteristics of this
system are:
- Bush-like structure with a wide central opening
- Crown style branch distribution to promote balanced vegetative and
productive growth
- Natural control of vegetative development, encouraged by higher
density
- Improved canopy root balance, resulting in more stable plants with
less excessive vigor
The goal is not to force the
tree, but to guide it toward a more efficient, stable, and productive form.
Why Move Beyond
the Traditional Policonic Vase
Although historically valid, the
traditional policonic vase now shows several operational limitations,
especially in contexts where management costs strongly affect profitability.
The main critical issues include:
- Operational difficulties due to plant height
- Greater pruning complexity
- Limited compatibility with mechanization
- High management and harvesting costs
The free, bush shaped vase system
offers a practical response to these limitations, providing immediate
advantages:
- All operations carried out from the ground, safer and faster
- Easier mechanization, both for pruning and harvest management
- Earlier entry into production
- Greater uniformity among plants
This is a system designed for
modern olive growing, where efficiency and sustainability must progress together.
Real
Sustainability: Producing More While Using Less
One of the most interesting
aspects emerging from this experience concerns the very concept of
sustainability.
Contrary to common belief,
increasing planting density does not necessarily mean excessive land
exploitation. On the contrary:
- Higher production per hectare reduces overall land consumption
- More oil is obtained from a smaller cultivated area
- Fewer passes by agricultural machinery are required
- Energy and environmental costs per unit of product decrease
True sustainability is not
producing little over large areas, but optimizing available resources by
improving overall agronomic efficiency.
Conclusion:
Freedom for the Tree
The Rieti experience shows that
there are no rigid or universal models. Each system must be adapted to soil and
climate conditions, cultivar characteristics, and farm objectives.
The Zaragoza free vase represents
a philosophy even before it is a technique: a structure that allows the tree to
express itself, but within clear rules suited to modern production needs.
A free but guided tree. A simple
form, yet extremely efficient. A model that looks toward the future of olive
growing.
