Contribution of Climate Change to Soil Carbon and Nitrogen Storages in Three Parent Materials in Akwa Ibom State, Nigeria- Juniper Publishers
Journal of Agriculture Research - Juniper Publishers Abstract A study was conducted to examine the effects of climate change on the Carbon and Nitrogen storages of soils derived from Coastal Plain Sands (CPS), Beach Ridge Sands (BRS) and Sand Stone/Shale (SSS) parent materials in Akwa Ibom State. Secondary soil data of organic carbon, and bulk density as well as climatic data of 2004 to 2014 were used. Organic C stock and SON were calculated as product of soil organic carbon (or total N) contents, bulk density and soil depth. Data were analysed using descriptive statistics, regression analysis and ANOVA at α0.05. Organic C stocks on the surface (0-15cm) soil depth were 44.13±15.91, 43.89±17.39 and 52.40±18.02Mg C ha-1 for CPS, BRS and SSS, respectively. The corresponding values for subsurface depth (15-30cm) were 28.30±9.58, 24.83±8.93 and 26.37±5.74Mg C ha-1. However, N stocks at 0-15cm soil depth were 3.37±0.90, 3.19±0.94 and 3.56±1.00Mg N ha-1 for CP...
