Agrology Success Stories – Increase in Olive Oil Production and Improvement in Quality Characteristics
Through Agrology Success Stories in Greece and Abroad, it is proven that the superior quality and integrated innovative technologies of Agrology’s Functional Crop Nutrition® products, make a difference in crops from the very first applications!
Our goal is to demonstrate that application programs with Agrology’s Functional Crop Nutrition® products are an obvious investment for producers, as the financial benefits exceed the cost of supplemental applications! More specifically, Agrology, in collaboration with Commercial Stores of Agricultural Supplies or Agricultural cooperatives, carried out a series of demonstrative applications in Oil Olives. Throughout the process, the farmer benefited from the continuous guidance and support offered by Agrology’s Technical Department and the collaborating agricultural stores or cooperatives.
The crop area of each trial was divided into two equal plots, one was used as the Control, while Agrology’s Program was applied to the other plot. The field trials intended to increase Total Olive Oil Production and Improve Quality Characteristics of Olive Oil and were conducted in different regions of Greece during the years 2018-2025.

Consolidated Success Stories Results
During the field trials, sampling was conducted in both the Control and Agrology Program treatments, while total yield was assessed at harvest. The Agrology Program significantly improved the agronomic performance of olive orchards for olive oil production, resulting in substantial benefits for growers.
Specifically, the following results were achieved:
- Increase in Total Olive Oil Production by 28.3% (+470 kg/ha)
- Agrology: 2.14 t/ha
- Control: 1.67 t/ha
2. Increase in Fruit Size
3. Increased resistance to abiotic stress factors
a) Average 52% Increase in Fresh Fruit Weight as a Result of Improved Protection Against Summer Heat Stress.
b) Foliar Application of Gravital® Energy in Olive Trees for Oil Production (Petroelia Variety)
- 2 Foliar Applications
- 1st application: Early July
- 2nd application: Early August
- No Rainfall for 4 Consecutive Months
- Irrigated Orchard
c) Foliar Application with Gravital® Energy (Arbequina Variety) – mid August
4. Leaf Analysis Results – Post Harvest (SS 2019_[37+82+83]_GR)
Leaf tissue analysis was performed on both the Control and the Agrology Program treatments after harvest.
Laboratory Assessment: The foliar application proved to be highly effective. Compared with the Control, the Agrology Program resulted in a significant increase in the concentration of all essential nutrients. The slightly deficient phosphorus level reflects its initially low concentration in the Control treatment. Equally important, the increase in nutrient concentrations remained within the optimal range, with no risk of nutrient toxicity, including micronutrients such as manganese.
5. Olive Oil Quality and Organoleptic Evaluation – Improvement of Olive Oil Quality Characteristics
The analyses were carried out by Angeliki-Efstratia Kouzoumi, MSc, Head of the Mytilene Olive Oil Laboratory, Hellenic Agricultural Organization – ELGO DIMITRA, Institute of Olive Tree, Subtropical Plants and Viticulture (IOSV), Kato Tritos, GR-81100, Mytilene, Lesvos, Greece.
The Agrology Program treatments showed improvements in free acidity, peroxide value, total phenolic content, and the organoleptic characteristics of olive oil compared with Control.
6. Health Certificate for Olive Oil
The World Olive Center Health Certificate verifies the concentration of bioactive phenolic compounds in extra virgin olive oil, including oleocanthal and oleacein, which are associated with important health benefits. It confirms whether the olive oil meets the requirements of the European Union Health Claim (EU Regulation 432/2012), demonstrating its ability to help protect blood lipids from oxidative stress. This certification provides independent scientific validation of the olive oil’s nutritional quality, functional value, and health-promoting properties.
Farmer’s Financial Benefit
The average increase in olive oil production of 470 kg/ha contributed to the increase of the farmer’s income, in various Olive oil prices.
