Rapidly rising atmospheric CO2 concentration and its potential impact on future climatic conditions is an issue of increasing global economic and political significance.
Soil respiration or soil flux can be defined as the net CO2 production of a soil, largely as a result of microbial decomposition of soil biomass. The amount of gas exchange taking place is frequently used as an indicator of the "health" of that soil. The rate of soil flux is influenced by a variety of environmental parameters especially organic matter content, soil moisture and soil temperature.
Spatial distribution studies
The SRS-SD1000 and SRS-SD2000 are ideal for conducting soil flux spatial distribution studies over a field site.
The availability of additional soil collars allows researchers to rapidly perform multiple soil flux measurements over a large experimental site, each collar being used to define a separate analysis area.
These stainless steel collars can be left in the soil enabling long-term comparative studies to be performed.
Adapters are available allowing researchers to use standard size soil waste pipes as alternative collars.
