Thinking about making your own olive oil? This guide from The Olive Centre explains what beginners must understand before starting. Budget machines under $10,000 often fail to produce real extra virgin olive oil, which requires proper crushers, malaxers, and decanters. The article covers each stage of extraction, from breaking down olive pits to controlled malaxation and centrifugal separation.

This article explores how key settings such as the choice between two-phase or three-phase systems and the differential speed (Dn) between the drum and screw directly shape the quality of olive oil.

The Curculio Beetle (Apple Weevil) is a destructive pest in olive groves, attacking leaves, shoots, and roots. This guide explains its life cycle, damage signs, and proven control strategies. Learn how pruning, sticky barriers, poultry grazing, and organic sprays like Formula V can help protect olive trees. Explore integrated pest management methods to safeguard your grove and reduce costly losses.

This article explores the unique hormonal controls behind olive fruit ripening. Unlike climacteric fruits that rely on ethylene, olives are primarily guided by abscisic acid (ABA), jasmonates (JA), and auxins. It explains how these hormones regulate color change, oil accumulation, and fruit drop, while highlighting ethylene’s limited but practical role in harvest management. Designed for growers and agronomists, it translates physiology ins

Learn how olive fruit retention force (FRF) and detachment index (DI) guide ripening, harvest timing, and mechanical efficiency while reducing fruit loss. Fruit retention (or detachment/removal) force is the tensile force needed to separate an olive from its pedicel at the abscission zone (AZ). It’s typically reported in newtons (N) or grams-force (gf) i.e. 1 N ≈ 102 gf. Most gauges measure a direct pull, but torsion and bending also matter in..

Olive trees often swing between heavy and light crops. This article explains why biennial bearing happens and how growers can manage it for steadier harvests.

This summer cropping season is facing unprecedented challenges in fertiliser supply. Availability of MAP fertiliser (monoammonium phosphate) and DAP fertiliser (diammonium phosphate) is expected to remain extremely limited worldwide, with serious implications for growers planning their nutrient programs.

The olive tree (Olea europaea L.) is a small, evergreen tree in the Oleaceae family and is native to the Mediterranean region. It has been cultivated for millennia and holds deep historical and cultural significance. In fact, olives are among the oldest fruit trees domesticated by humans, first cultivated around 6,000–8,000 years ago in the Eastern Mediterranean. From there, olive cultivation spread throughout the Mediterranean Basin....

The Australian olive oil industry has experienced rapid growth over the past three decades, evolving into a significant agricultural sector. With rising domestic demand, a strong export presence, and a reputation for high-quality extra virgin olive oil (EVOO), understanding the distribution of olive trees across the country provides essential insight into production capacity and regional specialisations.

Mechanical trunk shakers have transformed olive harvesting in modern olive groves. A new study: Damping behaviour of olive trees under trunk shaking (Ghonimy, Alharbi & Ibrahim, 2025) provides growers with the first detailed breakdown of how vibration energy moves through olive trees and the soil beneath them. The findings reveal how attachment height, trunk diameter, and the tree-soil interaction determine whether ...
