Precision Agriculture is about whole farm management with the
goal of optimizing returns on inputs while preserving resources
http://en.wikipedia.org/wiki/Precision_agriculture
Precision agriculture aims to optimize field-level management with regard to:
Crop Science: by matching farming practices more closely to crop needs (e.g. fertilizer inputs);
Environmental Protection: by reducing environmental risks and footprint of farming (e.g. limiting
leaching of nitrogen);
Economics: by boosting competitiveness through more efficient practices (e.g. improved
management of fertilizer usage and other inputs).
- Collection of real-time data on weather, soil and air quality, crop maturity
and even equipment and labor costs and availability
- Predictive analytics for smarter decision making

Photonics in Precision Agriculture
• It helps carry information (optical, chemical, physical, biological properties).
• Its module/system can process the information at a very fast speed via high-
speed large-data-packet communications or parallel processing.
• Real module/system involves other disciplinary such as Chemistry, Biology,
Electronics, Computer Sciences, Mechanics,…

Conclusion
• Optical sensors and systems for agriculture can be
operated from… far away
not too far away
in the farm
Satellites
Airplanes/Drones
Local sensors and systems
• It is not only about Optics and Photonics but
Multidisciplinary (Biology, Chemistry, Electronics
Engineering, Mechanical Engineering,…)
• We should choose the right spectra with appropriate
sensing & systems to answer the needs in each
application
