Climate change scenarios encompased IPCC scenarios RCP: 4.5 (with and without 538 ppm CO2 enhancement) and 8.5 (with and without 935 ppm CO2 enhancement) from climate data sources CNRM and IPSL. a–f Treatments included six continuous grasslands: G1 (grassland ploughed and restarted every year), G2 (grassland ploughed and restarted every two years), G3 (grassland ploughed and restarted every three years), G4 (grassland ploughed and restarted every four years), G6 (grassland ploughed and restarted every six years) and PG (grassland with no tillage); and g–i three crop rotations: CC (rotation of annual crops), C3G3 (rotation of 3-year grasses and 3-year annual crops), G6C3 (rotation of 6-year grasses and 3-year annual crops). Graphs show the mean and standard deviation across the 8 scenarios.
