Biomass and soil carbon stocks of Rhamnus prinoides based agroforestry practice with varied density in the drylands of Northern Ethiopia

Agroforestry plays a significant role in climate change mitigation through improved sequestration and storage of carbon in farmlands. However, quantitative information on above and belowground carbon inputs in agroforestry systems practiced is limited in the drylands is limited. This study estimated...

Description
Summary:Agroforestry plays a significant role in climate change mitigation through improved sequestration and storage of carbon in farmlands. However, quantitative information on above and belowground carbon inputs in agroforestry systems practiced is limited in the drylands is limited. This study estimated biomass and soil carbon stocks of Rhamnus prinoides based agroforestry practices in Ahferom and Ganta-Afeshum districts of Tigray region. Inventory was conducted on farms with R. prinoides intercropping of varied density. Destructive method was used to develop allometric models for estimating above and belowground biomass carbon. Undisturbed and composite soil samples were taken from farms with and without R. prinoides plants (open). The model based on diameter at stump height ( r  = 0.91) and height ( r  = 0.83) presented good fit (0.86
