Madagascar EcosolsEco&Sols is hosted by the Radioisotope Laboratory (LRI) at the University of Antananarivo.

The three research themes of Eco&Sols are studied in Madagascar in various farming systems: direct drilled rice crops, agroforestry systems, etc.

The LRI has the equipment required for routine soil analyses: soil preparation, soil sample library and standard texture, organic matter, mineral N, pH and CEC analyses, using continuous flow analysis and atomic absorption spectroscopy. It also has a diffuse reflectance (mid-)infrared fourier transform spectroscope (DRIFT) and a microcatharometer for gas analysis (CO2, N2O, CH4).

The LRI also has a soil biology laboratory for extracting, observing and handling the various soil organisms: bacteria, microfauna, macrofauna.

Equipment for particle size and densitometric separation and for soil incubation to measure microbial activity is available, as well as a greenhouse for plant trials.

A 32P measurement system, approved by the International Atomic Energy Agency (AIEA), is available for isotope dilution analysis.
