EJP-C-arouNd Project

Soil Conservation and Regenerative Practices to Enhance Carbon Sequestration and Reduce Greenhouse Gas Emissions.

In this international consortium, we aim to investigate how short- and long-term agricultural management practices influence the persistence of soil organic matter (SOM).

Improving soil conservation and regenerative practices to enhance carbon sequestration and reduce greenhouse gas emissions.
