INRA: Research site of Crouel & Experimental farm facility of Theix

The visit will be set up in two times:

1 - At INRA Crouel, you will be guided to :

i) Pheno3C

Pheno3C is a high throughput plant phenotyping platform dedicated to the study of crop tolerance to abiotic stresses under agronomic conditions.
The core of the platform is made of 4 large automatic rainout shelters that allow to generate and control water stress in the experimental plots. In addition, FACE (Free Air CO2 Enrichment) systems allow to control atmospheric CO2 concentration in the plots and thus, put the studied crop into desired future climatic conditions. The large number of environmental sensors hosted on Pheno3C provide a constant monitoring of micro-climatic variables and phenotyping tools (e.g. Phenomobile robot) and their sensors give an insight into the dynamic of plant growth.
In brief, Pheno3C is a tool dedicated to the scientific community that aim to study the genetic variability existing in crop species for their tolerance to abiotic stresses and ultimately to guide plant breeders towards genotypes adapted to future climatic conditions.


II) Mobile Laboratory for greenhouse gases CO2, H2O, CH4, N2O and their isotopes (13C, 15N)

- In the context climate changes studies and GHG inventories, a general need for data has arisen in order to get a better view of the contribution and functioning of agricultural- and natural ecosystems to GHG balance.

- In the ANaEE infra structure Project, has the objective to provide service and experimentations to i) enable targeted measurement campaigns, ii) serve as a support for in situ and non-destructive measurements and iii) provide facilities to measure GHG fluxes in terrestrial ecosystems.

- A mobile gas laboratory (Labmobile) was setup to responds to these requirements and to provide instrumentation to measure, in real time, the evolution of GHG fluxes (CO2, N2O CH4, with their isotopic signature 13C, 15N) between soil-plant-atmosphere of different (experimental) sites and on different ecosystems (meadows, crops, forests). The Labmobile is equipped for measurements of gas concentrations and flows at several scales ranging from cm2 to the plot (hectares); laboratory incubations measurements by uses of chambers (static and automatic) and flux tower facilities.


2 -At INRA Theix, you will be guided to :

INRA Experimental unit Herbipole which owns an experimental farm facility, which works on ruminant physiology and conduct ethology studies on dairy cows and fattening young cattle.

Experimental studies are conducted on 70 Holstein dairy cows (20 cannulated), on fattening young cattle, on 400 ewes and 40 cannulated sheeps.

On this facility the­ scales of research go from the organ to the animal (essentially cattle and sheep), in connection with products qualities (meat and milk) and environmental impacts.
The visit will focus on:
- Automatic recording of feed intake and eating behaviour,
- Installations and equipments to measure the in vivo digestibility of forages and diets and to study the eating behaviour and the ingestion of cattle and sheep,
- Breathing chambers and GreenFeed systems for the measure of methanogenesis (beef and small ruminants)
