Wireless sensor networks for precise Phytophthora decision support

Background. Precision Agriculture provides the optimal treatment for each production unit that can be distinguished and which can be individually treated in an efficient way. This agricultural practise is based on detailed information on the status of crops and soil. Most of this information focuses on techniques like soil mapping, yield mapping and remote sensing, which cover the spatial domain with more or less spatial resolution. The information is incidentally sampled and is therefore valid at the time the observations are made. Some of the processes like fertilization and especially crop protection require frequent updates in information. Sensor systems that are continuously present can deliver such information.
