Huelva, Spain
In 2025, NEVAL also conducted a study in Huelva, Spain on the impact of VESTA on strawberry plants. Once again, the results were significant, with positive impacts on:
Yield assessment. Increase of yield due to the action of VESTA was positive. The results showed significant differences at LSD 0,1 between the control and with VESTA with an increase of 22,5%.
Fruit weight. Improvement in the average weight per fruit due to the action of VESTA was positive, with statistically significant differences between the application of the biostimulant VESTA and the control, increasing the weight of the fruits in 5,44g per strawberry.
Fruit size. Increase in the size of the fruit due to the action of VESTA was positive with statistically significant differences between the application of the biostimulant VESTA and the control, increasing the diameter of the fruits by 0,31 cm per strawberry.
Sugar content. Improvement in the sugar content due to the action of VESTA was positive with statistically significant differences between the application of the biostimulant VESTA and the control, increasing the Brix degrees 0,28.

California, USA
Several comprehensive studies have been conducted in collaboration with leading universities and the USDA on strawberry plants, with results that are not only important for strawberry production, but for all crops.
The studies document that their is a very positive impact on the uptake of nutrients through the use of VESTA. For example, the VESTA treated plants in California took up 25% more Nitrogen and around 15% more Carbon than untreated plants. It was also shown that VESTA has a positive effect on the uptake of other nutrients.

Report – VESTA biological soil amendment dramatically shifted microbiota composition inside strawberry roots
Photos below illustrate the difference in the treated and untreated crops in California, with a clear increase in yield for the VESTA treated.
