Robotized solutions for field- and laboratory experiments

A robot for measuring emissions in field experiments

In collaboration with ADIGO, we have developed an autonomous vehicle that measures emissions of N2O and CO2 from the soil surface in field plot experiments.

The robot measures N2O with TDL with a frequency of 1 Hz, allowing emissions to be quantified with a closure time of 3 min.

Tha alpha-version is now in operation in our field experiments, where we test the effects of pH adjustments by lime and mafic minerals.

Documentation of the performance of the robot is found here

A beta version of the robot will be made commercially available by ADIGO, in collaboration with NMBU.

We are inviting research institutions to join in on this project, named TEMBO.

This video shows the robot in action and how it is controlled from the office:



The video also shows some interesting details regarding the "fast box" technique developed.


Robotics for gas kinetics in laboratory experiments

We have constructed a robotized incubation system (Molstad et al 2007) which allows tracking of electron flow to various electron acceptors (O2, NO2, NO and N2O) in 15 parallel cultures. The system can also be used to measure other relevant trace gases (CO2, CH4, NO and N2O) at or below ambient concentrations, and thus serves in situ flux measurements. Our lab is also equipped with tools for stable isotope analyses (13C, 15N, 18O, D/H) of organic materials and gases (N2O, CH4, CO2)

We have designed several more versions of this system (described here), replacing the microGC with traditional GC and an improved incubator/sampling system that allows parallel incubations of 30 stirred batches (+14 without stirring). One of these also includes H2 and H2S detection. Another, similar system will be installed in 2020.

We have also assisted in making replicas for:
