Application Description

Soil respiration monitoring is an important indicator for assessing the health of soil ecosystems. Laser gas sensing technology can monitor the release of CO2, CH4, and N2O from soil in real time, helping researchers to understand the dynamics of soil carbon cycle processes and microbial activities, and supporting agriculture, ecological restoration, and climate change research.

Industry Application Methods

  1. Field Automatic Monitoring System: Laser sensors are arranged in the research plots to continuously record the changes of CO2, CH4, and N2O concentrations released by soil respiration.

  2. Multi-Point Monitoring in Experimental Plots: Combining experimental treatments with different management practices (e.g. fertilizer application, irrigation) to monitor the effects of each treatment on GHG emissions.

  3. Carbon Sink and Climate Assessment: Comprehensively analyze soil respiratory fluxes and environmental parameters to quantify the carbon sink capacity of the soil and its response to climate change.

Comparison of Advantages and Disadvantage with Traditional Methods

Traditional Methods: Static box sampling combined with laboratory analysis, limited data and time-consuming.


Laser Sensing Advantages:

  • High Temporal Resolution: Enables real-time dynamic monitoring and recording of short-term changes in soil respiration

  • Simultaneous Multi-Gas Detection: Simultaneous measurement of CO2, CH4 and N2O, enhancing research efficiency

  • Automated Operation: Reduce manual operation, especially suitable for long-time unattended research scenarios
