«Absorption lines» have widely proved that the nutritional requirements of plants are in function of the phenological stage of vegetative and productive cycle.

Moreover nutrients are required with different intensity during the productive process. That’s why it is extremely important to apply all of them (macroelements, secondary elements and trace elements), in the most suitable moment and in the most convenient doses. The only possible way to reach this aim is that of using irrigation water as a vehicle for fertilizers.

Fertilization by irrigation makes it possible to dose the percentages of nitrogen, phosphorus, potassium and other secondary elements you wish in the most suitable moments according to the crop’s needs.

It is a very simple operation since the fertilizer is mixed with irrigation water regardless of which system you use: by sliding, by sprinkling, fertilization by hose irrigation, drip micro-irrigation, side infiltration system, etc.

Irrigation fertilizers

AGROFILL^® provides its customers with a full range of formulations created specifically for this agronomic technique: the “IDRON” line is for greenhouse crops and the “BULL” line for open beds crops.

Irrigation Fertilizers in soluble powder for greenhouse crops

Excellent fertilizers for excellent crops

IDRON line is made up of a wide range of water soluble fertilizers which have been especially conceived for fertigation of greenhouse crops. The high purity of the raw materials employed ensures a complete and excellent solubility. The special ratios existing between the various fertilizing elements make it possible to satisfy any nutritional need in any phenological stage of crops.
Trace elements - copper - iron - manganese – zinc - are completely chelated; boron and molybdenum are included in a particular and exclusive organic compound to ensure a quick absorption by plants.
IDRON fertilizers
- are free from chlorine and carbonates
- can be employed in any fertigation system with no danger of causing obstructions in the distribution equipments
- do not leave residues on leaves
- have a low conductivity
- have a strong acidifying action on substrates (compost, peat, …)
- contain special activators that stimulate root and foliar absorption of nutrients

N.B. IDRON formulations can be conveniently used also in foliar fertilization.
