Possibilities of targeted sprayings and weed killing by the use of sensors and precision farming
On the 45.00 m wide spray lines of the self-propelled Delvano spray machine of farmer Ch. Deprez 6 Trimble Green Seeker sensors will be mounted. This can measure the chlorophyll condition of the leaves optically by an infrared signal that can be reflected by the leave of the plant. On the basis of the observed condition of the leave a variable application of liquid nitrogen in the winter wheat will be used. Through this light green leaf spots will get more fertilisation administered than dark green leaves. This targeted fertilisation will be evaluated on the basis of a reference strip. The advantage of a variable fertilisation is a more efficient administration of fertilising resources that are more environmentally friendly and will lead to cost saving.
In addition, the technique is also applied for weed killing in potatoes in which the still highly green plants will get a higher dose of weed killer than already decayed patches in the plot. Here again the advantage of a more efficient use of weed killer resources results in a lower input of chemicals. Also the quality of the harvested potatoes will increase.
