Agrology Success Stories: Mandarin Earlier Ripening with XGel® Topaz

Mandarin Earlier Ripening with XGel® Topaz.

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 out in Mandarin oranges (SS 2018_1_GR) in collaboration with the Agricultural Association of Sagiada in 2017. Throughout the whole process, the grower benefited from the continuous guidance and support offered by both Agrology’s Technical Department, and the Agricultural Association of Sagiada.

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 main objective of this Success Story was to bring the fruit ripening earlier in order to secure better prices for the grower.

By using Specialized Plant Nutrition Products during specific growth stages, the producer can achieve to maximize his crop’s yield and quality.

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

Identity of Success Story

  • Cultivation Period: 2017
  • Location: Sagiada, Igoumenitsa
  • NutriMaster®: Agricultural Association of Sagiada
  • Owner of the Estate: Anastasiadis Ioannis
  • Cultivation: Mandarin
  • Variety: Klimentini
  • Plant Protection Program: Common to the whole crop

Special Nutrition Program

The program consisted of the complimentary single application with XGel® Topaz through foliar spray. The producer applied the product at the stage of maturation of the fruit (300 cc / 100 liters).

The producer applied the same Plant protection and fertilization program in both plots with the only exception being the supplementary application of XGel® Topaz.

XGel® Topaz  0-50-50+TE

A complex, fully water-soluble fertilizer with a high concentration of phosphorus and potassium in gel form, for application with irrigation systems and foliar sprays. It is organically activated with E2DA® factor and enriched with trace elements in chitin form. It increases the size and promotes the maturation of fruits, bulbs and tubers.

Composition: 50% w / v Phosphorus (P2O5), 50% w / v Potassium (K2O), Trace Elements (EDTA), E2DA® Factor

Difficulties in Nutrients Absorption

Many times, the application of nutrients from soil may not yield the desired results. This may depend on various problems that the soil or the crop faces due to current weather conditions. For example, excessive ammonia fertilization makes it difficult to absorb potassium from plants. Sandy soils are poorer in clay than clay soils. In clay soils, however, Potassium is bound to a considerable extent by clay. Therefore, the maintenance of sufficient availability of the element in the soil solution require larger amounts of fertilizer.

As a consequence, it is not enough to only ensure the proper application in terms of the vegetative stage and the quantity required. We must also make certain that plants absorb and transport these elements to the places they are needed into have the best results.

So, the innovative fertilizers of the XGel® line come to meet the above needs!

XGel® Line

XGel® Line is the result of research and development of Agrology in the creation of the next generation fertilizers. By incorporating E2DA® and S proprietary technologies, XGels® offer high concentrations, improved uptake and faster nutrient movement within the plant without sacrificing ease of use or stability. The XGel® line offers high-yield NPK for every stage of development, capable of increasing performance and quality.

Features & Benefits:

E2DA® Technology:

Enhanced nutrient intake and increased efficacy.

S Technology:

High susceptibility, efficacy and absorption of nutrients.

No precipitation or phase separation.

High Concentrations:

Reduced doses and increased efficiency resulting in lower implementation costs.

High Quality Raw Materials:

It ensures maximum efficiency and safety without chlorine.

Enhanced Combination Profile:

Facilitates combined application for reduced implementation costs.


Certified manufacturing processes ensure long shelf life.

Success Story Results

Sampling and yield measurement on both pieces revealed impassive results in the Agrology plot.

More specifically, the results were as follows:

  • Earlier mandarin production by 1 week, compared to Control!
  • The earlier production of mandarin resulted in the sale of the product at a higher price / kg (+0.05 € / kg)!

Investment – Producer’s Benefit

The earlier production contributed to the grower’s revenue increase by 2500 € / ha. (Increase in price Kg: 0.05 € – The producer himself provided the information on the following average kilo prices), while the cost of the additional applications was only 70,00€ / ha.

Average Percentage of Mandarin Growth per ha: 50.000 kg
