The new Complex Plus complex fertilizer with DCD, manufactured from potassium sulphate, offers the farmer a slow-release chlorine-free nitrogen fertilizer solution, ideal for fertilizing horticultural crops.

Nitrification inhibitors (DCD): these are compounds that delay the conversion of ammonium to nitrite in the soil by inhibiting Nitrosomonas bacteria for a certain period of time. Thanks to the DCD, nitrogen release takes place gradually, at the rate of absorption required by the crops. This is why slow-release nitrogen provides greater efficiency, is more usable and is therefore more efficient.

In addition, its unique composition with potassium sulphate, which is chlorine-free, favours the yield and the quality of the harvests.

Nitrogen: It contains nitrogen in two forms, nitric and ammoniacal, which along with the DCD content prolongs its availability for the crop.

Phosphorus: It is 100% assimilable. Its high solubility in water facilitates its transport to the root of the plant.

Potassium: Originating in the sulphate, it is completely chloride-free, reducing the salinity of the soil.

Magnesium: Increasingly in demand due to a lack of this element in soils, magnesium is the central molecule of chlorophyll and as such improves photosynthesis in the plant.

Sulphur: The acidifying effect of sulphur in the soil facilitates the gradual release of nitrogen and complements the effect of DCD.

Form of application

It is advisable to apply NPK complex fertilizers homogeneously on the surface of the soil and, if possible, dig them in so that they get near the roots. This facilitates the absorption of phosphorus and potassium, which are elements that are not very mobile.

In the case of tree crops, it can also be located between the rows.

It is recommended that all NPK complex fertilizers are applied:

  • Shortly before sowing in the case of herbaceous crops.
  • At least one month before sprouting in the case of tree crops, or in other words, far enough in advance before the plant needs the nutrients that we supply.
