Eco-mind - Model LK-2200 -Multi-channel automated subsurface-surface greenhouse gas

As global change research becomes more widespread, the measurement of gas fluxes is of increasing interest. Gas fluxes are usually measured at the plant leaf-atmosphere interface, at the soil surface-atmosphere interface and at the ecosystem-atmosphere interface. Because of the spatial heterogeneity of soils, soil respiration varies considerably even within the same soil type in the same block, and scientists need to conduct multi-dimensional studies in space, time and gas type to better explain the mechanisms underlying soil respiration. It can also be configured with a variety of gas isotope analysers and has excellent scalability to connect to 8, 16 or 24 channel respiration chambers or transparency chambers and soil profile gas sampling probes. The multi-channel soil respiration measurement system provides a new technique for high frequency monitoring of trace gas concentrations in soil pores to investigate the effects of temperature, soil moisture and fertiliser inputs on trace gas fluxes, yields and consumption. The continuous and simultaneous monitoring of multiple greenhouse gases at different subsurface-surface locations allows a better understanding of the changes in soil response to climate, as well as access to the linkage mechanisms within the soil and at the soil-atmosphere interface and the different responses to climate change.
