Carbon Sequestration

“C and N mineralization following organic amendment additions varied at different soil moisture levels. While biochar and compost can increase GHG emissions, optimizing water management can help reduce GHG emissions.”

“Biochar application reduced cumulative N2O–N and CH4–C emissions by 52% and 16%, respectively. Biochar-treated soil had the lowest cumulative N2O–N and CH4–C emissions, reducing net global warming potential (GWP) by 43% and 30%, respectively, compared to compost-treated soil and control”

“Across 648 soil profiles in North Carolina, particulate organic matter — the fraction most responsive to management — made up 35% of total soil organic C in the top 10 cm but only 10% at 30–60 cm, and was lower in sandier soils. Poultry litter application raised root-zone particulate organic C and N by 17%–32%, and pastures 30 years old held 4%–20% more than newer pastures, while deeper, stable (nonparticulate) carbon was set by long-term soil formation rather than management.”

“After 27 years of no-till in central Ohio, compost and manure raised topsoil (0-20 cm) carbon stocks about 66%-67% above fallow, with compost sequestering 0.85 Mg C/ha/yr and manure adding the most nitrogen (0.061 Mg N/ha/yr); cover crops alone gave a smaller 21%-27% gain. Higher soil carbon tracked better aggregate stability (R2 = 0.76) and lower bulk density, though compost also pushed up salinity near the surface.”
