What is Carbon storage in soils of Southeastern Nigeria under different management practices about?

## Background: Changes in agricultural practices-notably changes in crop varieties, application of fertilizer and manure, rotation and tillage practices-influence how much and at what rate carbon is stored in, or released from, soils. quantification of the impacts of land use on carbon stocks in sub-saharan africa is challenging because of the spatial heterogeneity of soil, climate, management conditions, and due to the lack of data on soil carbon pools of most common agroecosystems. this paper provides data on soil carbon stocks that were collected at 10 sites in southeastern nigeria to characterize the impact of soil management practices. ## Results: The highest carbon stocks, 7906-9510 gc m-2, were found at the sites representing natural forest, artificial forest and artificial grassland ecosystems. continuously cropped and conventionally tilled soils had about 70% lower carbon stock (1978-2822 gc m-2). thus, the soil carbon stock in a 45-year old gmelina forest was 8987 gc m-2, whereas the parts of this forest, that were cleared and continuously cultivated for 15 years, had 75% lower carbon stock (1978 gc m-2). the carbon stock of continuously cropped and conventionally tilled
