Planting and management of improved grass in tropical savannas can increase soil carbon by 15%

by The Alliance of Bioversity International and the International Center for Tropical Agriculture

An improved variety of grass combined with a rotational grazing system can boost levels of soil carbon on tropical savannas by 15% compared to degraded pasture, a new study performed by the Alliance of Bioversity International and the International Center for Tropical Agriculture (CIAT), the University of Stuttgart, and the World Bank has found.

Scientists tested Urochloa humidicola, or Koronivia grass, on an 8,000-hectare cattle ranch in Vichada, Colombia, and found soil carbon stocks 15% above the control grassland, which itself had 40% higher carbon stocks than the default value provided by the IPCC.
