Montpellier EcosolsEco&Sols is on the La Gaillarde campus of Montpellier SupAgro and most of its personnel work in buildings 12 and 13.

The 3 research themes of Eco&Sols are covered, as well as the 2 transversal disciplines.

Unlike the sites in developing countries, the Montpellier site is mainly concerned with experiments in controlled conditions, soil incubation, including tropical soils in a quarantine laboratory, plant cultures and cultivation of macrofauna in various mesocosms, greenhouses and growth chambers.

Most of the field trials are carried out in the experimental sites of the INRA DiaScope Experimental Unit in Mauguio, south of Montpellier, in particular on the OC (Organic/Conventional) experimental site, where 10 ha were converted to organic farming in 2008, as well as using a system for studying Mediterranean agroforestry subject to water stress that is being set up.

Many of the activities of the Montpellier site are concerned with observations or experiments carried out in a network of plots belonging to farmers or forestry stands in various regions of France as well as trials in agronomy sites such as the long term phosphate fertiliser trial carried out by INRA in Toulouse-Auzeville.

Eco&Sols has five laboratories in Montpellier which provide services for all the experimental and analytical activities of the Montpellier site as well as undertaking many analyses for the various sites in developing countries.

Life science laboratory

This laboratory is mainly concerned with facilities management and producing experimental devices for culture in controlled conditions (micro- and mesocosms). The main facility comprises a growth chamber with shelf area of 6 m2 and a containment level 2, air-conditioned greenhouse with a shelf area of 18 m2.

The EcoTrop project which began in 2016 will include a confined growth chamber that can be used to control CO2 concentrations to simulate climate change. This laboratory also carries out plant morphometric analyses, in particular of roots, using digitising tablets and WinRhizo, a complete plant root measurement system, as well as field experiments around Montpellier and in the south of France.

BioSolTrop laboratory

This containment level 2 laboratory studies organic matter, in particular using near infrared (NIRS) and mid infrared (MIRS) spectrometry, and particle size fractionation and densitometry. Soil biological activities are characterised by measuring biomass and microbial activities. An elutriator is used to extract soil nematodes which can then be identified and quantified.

The laboratory was accredited to handle soils imported from other countries in 2008. Accreditation applies mainly to tropical soils.

The laboratory has two soil libraries, one of which is in a containment level 2 facility.

Biochemistry laboratory

This laboratory develops techniques and methods for studying biomolecules in various biochemical fields, in particular proteins and enzymes. It is classified as containment level 2 and is, therefore, able to study hazardous proteins such as prions and the avian flu virus and the possibility of extending research to other biomolecules may be considered.
