The rate of soil carbon turnover: a matter of depth

Agroecology

The incorporation of organic carbon into soil helps to regulate both the amount of CO2 in the atmosphere and the fertility of agroecosystems. Researchers from INRA, CEA, and CNRS are the first to quantify the rate of carbon incorporation into soils according to depth and its anthropic and climatic determinants. The study opens up new perspectives that allow us to better appreciate the evolution of the carbon cycle.

Win-win strategies for climate and food security

Climate Change

Climate policies that target agriculture and forests could lead to increased food prices, but reducing deforestation and increasing soil carbon sequestration in agriculture could significantly reduce greenhouse gas emissions while avoiding risk to food security, according to new research published in the journal Environmental Research Letters.

Biodiversity when restoring soil through fallowing: stronger interactions among organisms, increased carbon uptake in soil

Agroecology - Results, Innovations, Transfer

As a part of the EU’s EcoFINDERS project, led by INRA, researchers studied changes in soil biodiversity when using fallowing as a restoration strategy. The findings, published in Nature Communications, demonstrate that connections between groups of soil organisms increased, and this was accompanied by increased carbon uptake in the soil. Understanding these phenomena should help identify agricultural practices which favour carbon transfer and storage in soils.

How plant roots sense and react to soil flooding

Plant biology

Researchers from CNRS and INRA have just discovered a mechanism that allows a plant to adjust its water status and growth according to different soil flooding conditions. The results of this study, published on 15 September 2016 in the journal Cell, describe how roots sense and respond to soil oxygen and potassium levels jointly, so as to change their water uptake capacity.
