In a crop as technical as that of cherry trees, the approach and management of fertilisation must be a major aim, as it has a direct impact on production and its quality parameters.

At INPROG, we offer a balanced and comprehensive fertilisation for the entire crop cycle, while focusing on creating reserves and ensuring that the crop has all the elements available at all times.


Fruit set

In order to achieve a large fruit set in the first flowering period, a tree needs to have accumulated large reserves. To ensure these reserves, the plant needs to have all the #microelements and essential elements available.

INPROG fertilisers efficiently provide all the nutrients to build up the necessary reserves for a large fruit set.

Calibre, Brix, colour and firmness

The key parameters for cherry growing are as follows:

  • Calibre: In a crop with a short cycle, it is essential that nutrients are available from the onset of vegetation. The supply of these nutrients bound to organic matter ensures that they are always available.
  • Brix and colour: Brix and colour are closely linked to potassium and sulphur. That these nutrients are in assimilable forms guarantees the crop’s success.
  • Firmness: Obtaining a firm and elastic fruit is linked to a correct absorption of calcium and potassium. Guaranteeing both elements improves this parameter.

FORTEC and NUBIECOL, both for their manufacture and their technology, guarantee the final result of the harvest and the nutritional recovery of the plant, thus improving all quality parameters.

Key nutrients

There are four nutritional elements in cherry trees that are key to high yields:


Low calcium content has an impact on fruit firmness.


Low sulphur contents in the soil lead to lower chlorophyll contents and reduced fruit colour (polyphenol production).


Zinc deficiency reduces the crop’s yield potential. Low levels considerably reduce the production capacity of complex sugars as well as calibres.


To ensure good flower buds (florets), it is essential that the plant has this nutrient.


Low potassium contents cause Brix deficiency and hinder fruit colour.

The FORTEC-FR and NUBIECOL ranges naturally contain a large amount of these 4 elements, thus providing an easy, direct and efficient solution for cherry tree fertilisation.

Prevention of nutritional deficiencies

In short-cycle crops, it is particularly important to anticipate deficiency states, as there is no time for reaction. These deficiencies have a crucial influence on both quality and yield.

In most cases, nutritional deficiencies become visible when the condition is severe. Prior to this, the crop has already undergone stress, which has a direct impact on production. It is very important that the most scarce or least available nutrients are always available from the onset of the vegetative cycle.

In cherry trees, these are as follows:

  • Calcium
  • Iron
  • Zinc
  • Manganese
  • Sulphur
  • Boron
  • Molybdenum

The annual supply of FORTEC-FR and NUBIECOL fertilisers guarantees the correct nutrition of the crop, thus preventing visible or non-visible nutritional deficiencies. The annual supply of all the essential minerals bound to a stable organic matter of noble origin (#multifem) is crucial.

Cumulative effect

The supply, year after year, of the FORTEC-FR and NUBIECOL products improves production both in terms of calibres and kg/ha. This is the conclusion obtained in a trial at IRTA-Mas Badia on the cultivation of apple trees. These results can be applied to all woody crops.

This increase is due to the accumulation, in the soil, of #microelements and essential elements available to the plant. This allows the plant to regulate itself and produce more and better.
