For gathering the final results of a season-round crop work, the georeferenced
yield is a key piece of information. Harvesting equipment can be equipped with sensors to gather such information. Systems based on different technologies (impact, volume, optics, density, gravity…) will be explained for recording the yield flow inside
the machinery, during the harvesting. Adaptations of yield sensors depending on the commodity, along with new sensing systems will be discussed. Sensor for quality quantification will also be explained, as they are important for certain crops. Basic
procedures for the calibration of the sensing system and the proper registration of yield data to generate a successful yield map are presented.

In this topic the basic principles of sensors to gather information about plant status are explained. Mainly optical sensors, but also systems based or other principles, vegetation sensors will be presented as well as their use to register information about crop health, physiological activity, possible pest infestation, water content, and so on. Information acquired by these sensors (normally optical signals) must be processed adequately and, in many cases, converted into vegetation indexes that will be presented for different cases of usage.

Sensors for estimation of soil properties will be explained in this topic. Principles about soil sensors based on different technologies (electroconductivity, magnetic response, NIR optical signals, mechanical resistance…) will be presented. Relation between these sensors and soil attributes related to fertility are important in order to extract relevant agronomical information out of soil maps.

Sequence ID: 16
In this topic the technologies realted to wireless sensor networks (WSN) will be presented. The different parts of the network (nodes, gateway, data transfer protocols...) will be explained, as well as the sensors themselves (sensors for soil humidity, temperature, presure, precipitation, crop physiology, pest detection, etc.)
