Our ambition

To feed the agro-ecological transition

Our conviction that a better understanding of soil health will enable us to help farmers on a daily basis to meet the challenge of adapting to climate change and to provide a solution by sequestering carbon.

Underestimated for too long, soil life deserves our full attention, based on the founding principles of Terra Mea :

the humility

we all need to deal facing the complexity of living things. The science of soil health is new, and the impact of our actions is still being consolidated, which means we need to continue the scientific work we are doing every day, and to listen to what people have to say.

the innovation

to provide reliable, economical and fast measurement, analysis and advice tools. We need to be able to help farming practices evolve by regularly and easily measuring the impact of the choices made by the farmers.

the desire to adapt

that guides our research and consultancy work. There is no one-size-fits-all solution that can be applied to all sectors or all regions, but rather a tailor-made approach that responds to specific conditions and challenges.

a vision

that we are finally claiming for ourselves. Agroecology deserves to be pursued as a policy of results rather than means, underpinned by scientific data and field experimentation.
