Maize fertilisation

The extensive irrigated crop par excellence. Its high yields involve high extractions, which in turn deplete soil nutrients, especially #microelements, as only NPK fertilisation is carried out.

With an organic or organomineral fertilisation, followed by another nitrogen fertilisation, we achieve the balance of nutrients that the soil needs.

INPROG fertilisers incorporate the necessary #microelements to restore extractions and recover the desired high yields.


Damaged soils

Extensively cultivated soils suffer from overexploitation, hence leading to a loss of chemical and organic fertility. The first step to solve this problem is the supply of organic matter.

An organic or organomineral fertiliser is a smart way to solve the problem. VERDE, VERFOR, Gallicompost and NUBIECOL are specifically designed for this purpose.

Production parameters

When growing MAIZE, the following main fertilisation objectives are sought:

Quick stalk formation: In maize, vigorous growth from the birth of the plant is essential. Part of the success is to accumulate the maximum amount of nutrients and assimilated items (proteins, sugars, etc.) before flowering.

Increase in ear weight: The supply of #microelements, especially zinc, sulphur and calcium, increases the number of grains per ear and the specific weight of the grains.

Facilitating crop management: A supply of P+K+S+Ca+ Zn bound to organic matter improves their assimilation by increasing the amount of these nutrients available to the plant.

FortecFR, Verde, Nubiecol or Gallicompost, together with mineral nitrogen applications, improve the nutrition of cornfields.

Essential nutrients

In maize, three nutrients are usually neglected in fertilisation:


The lack of zinc decreases the crop’s productive potential, thus decreasing the specific weight of the grain.


It increases chlorophyll content and improves nitrogen transport within the plant.


Low levels of calcium in the soil can lead to a weak and brittle stalk. In turn, it reduces grain starch, hence reducing yields per hectare.

The FORTEC-FR, VERDE, Gallicompost and NUBIECOL ranges naturally contain a large amount of these 3 elements, thus providing an easy, direct and efficient solution for fertilising with these nutrients.

Cumulative effect

The supply, year after year, of the FORTEC-FR and NUBIECOL products improves production and yield in kg/ha. This is the conclusion obtained in trials carried out by the company and in research centres.

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.
