The innovative contribution of this research lies in designing, developing and validating a simplified technology platform consisting of a hardware for monitoring of gaseous emissions, such as Volatile Organic Compounds (VOCs) from the soil-plant-atmosphere system of crops, i.e., tomato. We analyzed experimental data acquired in situ by portable sensing units based on Metal-OXide (MOX) gas sensors, thus comparing the results with meteo-sat data and farming operations. A dependence of gaseous emissions on the hydric/metabolic status of the plants together with a correlation between collected sensor signals and significant events for the crops were proved. Finally, for each crop, we identified and calibrated one sensor to assess their water state.

Abstract
The innovative contribution of this research lies in designing, developing and validating a simplified technology platform consisting of a hardware for monitoring of gaseous emissions, such as Volatile Organic Compounds (VOCs) from the soil-plant-atmosphere system of crops, i.e., tomato. We analyzed experimental data acquired in situ by portable sensing units based on Metal-OXide (MOX) gas sensors, thus comparing the results with meteo-sat data and farming operations. A dependence of gaseous emissions on the hydric/metabolic status of the plants together with a correlation between collected sensor signals and significant events for the crops were proved. Finally, for each crop, we identified and calibrated one sensor to assess their water state.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
