Responses of CO₂ emissions and soil microbial community structures to organic amendment in two contrasting soils in Zambia.

ABSTRACT: In sub-Saharan Africa, efforts have been made to increase soil carbon (C) content in agricultural ecosystems due to severe soil degradation. The use of organic materials is a feasible method for recovering soil organic C; however, the effects of organic amendments on soil microbial communities and C cycles under C-limited soil conditions are still unknown. In this study, we conducted field experiments in Zambia using organic amendments at two sites with contrasting C content. At both sites, temporal changes in soil carbon dioxide (CO₂) emissions and prokaryotic community structures were monitored during the crop growing season (126 days). The organic amendments increased CO₂ emissions and prokaryotic abundance at the Kabwe site, whereas no direct impacts were observed
