Agrology Success Stories: Increase of Strawberry Firmness

Agrology’s Success Stories 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 as their economic benefits far outstrip the cost of the complementary applications!

One such Success Story was carried in strawberry (SS 2018_8_GR) in collaboration with Lainas P. in 2018. Lainas P. is an agrodealer and part of our NutriMasters® network in Greece. Throughout the whole process, the grower benefited from the continuous guidance and support offered by both Agrology’s Technical Department, and Lainas P.

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 Program included the implementation of Specialized and Innovative Plant Nutrition Product, Gravital® Force. It is important to mention the importance of application timing, that allowed producer to maximize the agronomic benefits.

The objectives of this Success Story were as follows:

  1. Increase Fruit Resistance against post-harvest rotting
  2. Increase Fruit Durability against post harvesting chain handling
  3. Improve Strawberries Firmness (reducing the “maceration” of the strawberry fruits)
  4. Reduce Total Fruit Losses in retail market
  5. Increase Strawberry Shelf-life

Success Story Results

Measurements during fruits shelf life revealed impressive results in the Agrology treatment. Specifically, the results were as follows:

  • Improve Strawberries Firmness (reducing the “maceration” of the strawberry fruits)
  • Reduce of the softened fruit percentage after 6 & 7 days maintenance at room temperature
