Understanding root and soil function is essential for understanding plant and ecosystem dynamics. Soil C loss via CO2, and methane emissions are major contributors to climate warming. Roots influence carbon cycling, microbial communities and nutrient availability. Root respiration, a key indicator of activity, is crucial in plant physiology and ecology research. The rhizobia-driven N-fixation of legumes has a major impact on the nutrient balance of ecosystems. Different technologies assess soil and root respiration (CO2 and/or O2). In addition, a non-destructive technique measures N fixation rates in legumes based on H2 evolution.
Q-SR1LP Soil Respiration Package, CO2 Efflux. In addition to CO2 (0-2000 ppm range), this package measures soil temperature, soil moisture and atmospheric pressure as major factors influencing soil respiration rates. Battery pack for ~11 hours of field use, and lab analysis of soil respiration in the incl. flow-through chamber.
Soil Methane Emission. Soil CH4 emission can be quantified in the field and lab in three ranges of up to 100 ppm, up to 500 ppm or to 5000 ppm with the reliable and cost-effective methane analyser series.
Q-RP1LP Root Respiration CO2 Efflux - Larger Root Samples. Low Range Root CO2 Efflux Measurement, ...
... details coming soon.
Q-OX1LP-R O2 Consumption - Small Root Segments. Oxygen (O2) consumption measurements in liquid media are frequently employed to assess root respiration, offering a direct window into the metabolic activity of root segments such as root tips or specific root orders (due to the limited cuvette volume).
Q-NF1LP Nitrogen Fixation Package, the only complete experimental package for measuring nitrogen fixation in H2-producing legume symbioses (H2 evolution). and to measure nodulated root respiration (CO2) in parallel.
