Agrology Success Stories: Olive Oil Content Increase

Agrology’s demonstrate the ability of Agrology’s Specialty Plant Nutrition Products to make a difference even from the very first application!

Our aim is to show that Agrology’s Nutrition Programs are a profitable investment for the grower because their economic benefits far outstrip the cost of the complementary applications!

One such Success Story in oil varieties of olives (SS 2018_9_GR) was in cooperation with  the EAS Aegialias Union of Cooperatives; a member of Agrology’s NutriMasters® network, in 2018. Throughout the whole process, the grower benefited from the continuous guidance and support offered by both Agrology’s Technical Department, and EAS Aegialias.

Initially the crop area was divided into two equal plots, that consisted the 2 treatments of the Success Story. One was used as the Control plot, while Agrology’s Program was used in the second. In both treatments, the producer made use of same plant protection and plant nutrition – fertilization program. Agrology’s Specialized and Innovative Nutrition and Fertilization Products application was complementary in the trial plot.

Success Story Goals

The objective of this Success Story was to increase the oil content of the olives.

The Program included the implementation of Specialized and Innovative Plant Nutrition Products, more specifically, Gravital® Force & XGel® Ruby. Moreover, the implementation took place during certain stages of olives growth and the producer to achieve significant agronomic benefits.

Beyond the above complimentary applications, the producer applied the same Fertilization/Plant Nutrition and Pesticide program, in both plots (Control + Agrology Program) throughout the growing season.

Success Story Results

The plots were harvested separately, and the oil extractor was meticulously cleaned before each use. The extrusion of the two treatments was in separate mills. Measurements of the yield and oil characteristics revealed the following results.

Oil content was increased by 21.6% compared to the Control (or + 4.35% of oil content):

  • Agrology: 24.50%
  • Witness: 20,15%

Investment – Producer’s Benefit

The 21.6%  increase in olive oil content contributed to the increase of the producer’s income by € 538.20,  when considering the price of  1t oil at the time which was € 2.70 / kg (average olive oil in Ilia € 2.70 / kg – Source: press).

The indicative cost of complementary applications with Agrology’s Specialized and Innovative Plant Nutrition Products amounts to € 290.63 / ha.
