After sowing, during the autumn, every culture takes from the soil the quantity of nitrogen needed.
At the end of the winter, when vegetation starts again, the nitrogen quantity is thus determined. At the end of the winter in line with nitrogen quantity in the soil and expected mineralisation there is a possibility to recalculate the total nitrogen quantity recommended for the targeted crop production.
SkyFert technology contains satellite pictures to determine green mass at the end of the winter and an Airbus algorithm system to evaluate it.
This technology gives the possibility to any farmer to recalculate the total nitrogen quantity in order to comply with the actual status of the plant and soil.
