Foster soil carbon in agriculture of soil?

  • We know that :
    • - Soil organic matter dynamic is a crucial component of soil functions providing ecosystem services
    • - Soil carbon sequestration could produce negative emission contributing to climate change mitigation
  • But constraints to increase soil carbon are multiple :
    • - Soil degradation, water and nutrients availability limit primary production and consequently soil organic matter building
    • - The soil carbon sinks has a finite capacity
    • - Land use and soil management reduce the residence time of sequestered C
    • - The social and economic contexts drive agricultural activities
