Radio telescope

The first wireless sensor network for agriculture was placed this week in a potato field in Drenthe. The network is part of LOFAR (Low Frequency Array), a unique radio telescope that consists of 25,000 antennas spread over a wide area to form one large antenna. Part of the telescope’s advanced and superfast glass fibre network is now being used for 150 sensors that measure the temperature and relative humidity of the potato crop. The project, LOFA_Agro, is led by A&F and is intended to help improve prediction of the potato disease phytophthora. The researchers are hoping to develop a new generation of advisory systems for precision agriculture. / GvM
