«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.

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.
