Item Open Access Effects of anthropogenic activities on soil carbon storage and compactness in coastal plain soil of tropical urban area(U. P., 2015-11) Udebuani, A. C.; Obasi, K. O.; Ezeji, E. U.; Okereke, J. N.; Anyado, S. O.; Dike-Ndudim, J. N.; Enekwu, E. C.The study on the impact of anthropogenic activities of a tropical urban soil; effects of different land use on bulk density, relative bulk density and their capacity to store carbon were investigated using several key soil physical and chemical properties such as ammonium acetate methods used for determination of cation exchange capacity. Results obtained showed the soil textural class to be sandy in all the land used area. Moisture content and porosity were highest in the automobile servicing area. Bulk density (1.50g/cm3) and relative bulk density (0.82g/cm3) were highest in soil samples from commercial area. Automobile servicing area had the lowest soil pH (5.1), compared to other land use areas, which had it pH ranging from 6.2 – 7.5. The highest value of exchangeable base was obtained also from automobile servicing area compared to other anthropogenic active areas. There is a considerable variation in the total carbon storage from different land uses with the highest carbon storage obtained from automobile servicing area (570.5 g/cm3), this is followed by soil samples from commercial areas (370.0 g/cm3). The lowest value of carbon storage was obtained from institutional area. The major effect of anthropogenic activity is on soil organic matter (OM); therefore, the degree of compactness was as a result of the impact on organic matter. Result of this present investigation shows that anthropogenic activities in urban environment affect the compactness and carbon storage of soil.
