Long-term annual burning of grassland increases CO2 emissions from soils
Grasslands have potential to mitigate against climate change because of their large capacity to store soil organic
carbon (SOC). However, the long-term impact of grassland management such as burning, which is still common
in ...
Maize productivity and profitability in Conservation Agriculture systems across agro-ecological regions in Zimbabwe: A review of knowledge and practice
Conservation agriculture (CA) is increasingly promoted in southern Africa as a strategy to improve food
security and reverse soil degradation in the face of climate change. However, the performance of CA
under different ...
Tillage impact on soil erosion by water: Discrepancies due to climate and soil characteristics
No-tillage (NT) is promoted for soil and water conservation, but research
findings on overland
flow and
soil erosion are inconsistent across different ecosystems, with some studies showing no benefits of NT
over conventional ...
Overgrazing decreases soil organic carbon stocks the most under dry climates and low soil pH: A meta-analysis shows
Grasslands occupy about 40% of the world’s land surface and store approximately 10% of the global soil
organic carbon (SOC) stock. This SOC pool, in which a larger proportion is held in the topsoil (0–0.3 m), is
strongly ...
