CANETE

Microbial efficiency in the use of soil carbon and nutrients in managed terrestrial ecosystems

Coordinating institution : INRAE

Project leader : Gwenaëlle Lashermes
Project duration : 60 months | October 1st 2024 → September 30th 2029

Grant : 1 488 003 €

Institutional partnerships : Sorbonne Université - Université Paris Saclay - ENS

Associated institutions : AgroParisTech - Université de Reims Champagne Ardenne - Université de Lorraine - Agro Montpellier - CNRS

The CANETE project aims to assess and predict microbial physiological responses to agricultural and forestry management practices across different pedoclimatic contexts, as well as their consequences for the coupling and decoupling of carbon, nitrogen, and phosphorus (C–N–P) cycles. Particular attention will be given to impacts on soil carbon and nutrient storage, nutrient supply to plants, and plant productivity.

The research will focus on terrestrial ecosystems shaped by several years of contrasting management practices, including annual cropping systems, temporary grasslands, agroforestry systems, and forests. These systems will be compared under practices that are expected either to disrupt or to enhance the coupling of biogeochemical cycles.

The CANETE project will help identify how soil microbial communities can be steered as a potential lever for more efficient use of carbon and nitrogen in terrestrial ecosystems. The project will deliver open data, model formalisms to simulate key microbial mechanisms, and enhanced decision‑support tools for projecting soil carbon and nitrogen stocks. It will also provide criteria to assess ecosystem services, supporting informed choices about trade‑offs between carbon storage, plant nutrition, and greenhouse‑gas emissions across a wide range of terrestrial ecosystems.

The project brings together a consortium of 15 laboratories and 9 long‑term experimental sites, with work organised into four research axes combining experimentation and modelling.
