Abstract
This study examined the forms and distribution of nitrogen in selected domestic dumpsites
in Ughelli Metropolis, Delta State. Soil samples were collected using the soil auger from three different sample locations in Ughelli Metropolis, Ughelli North Local Government Area Delta State. The soils were analyzed for some chemical and physical physical properties determined include the soil textural classes such as sands, clays, and silts. Some chemical properties studied in this experiment included pH, Total Nitrogen, Organic Nitrogen, Inorganic Nitrogen, Exchangeable Cations, Available Phosphorus, Organic Carbon, and Organic Matter. The results show that the predominant textural class was sand, with varying proportions of sand, silt, and clay. Sites 1, 2, and 3 had material compositions, with total sand dominance in the topsoils and increasing clay contents at increasing soil depths (30 - 60 cm). pH values ranged from 6.40 to 5.79 with mean value (6.10), 6.11 to 5.57 with a mean (5.18), and 6.61 to 5.63 with a mean (6.12) in Sites 1, 2 and 3 respectively. Organic carbon content was highest in topsoils (0 - 30cm) across all sites while total nitrogen exhibited variations across soil depths with high amounts in the topsoils (0 -30cm). Available phosphorus content decreased down soil depths, while exchangeable cations showed soil depth-related trends. The presence of exchangeable cation decreased with depth. However, there was little or no changes in the contents of Magnesium and Potassium at 30-60cm depth across sites 2 and 3. Exchangeable Acidity was found to increase with increasing depth across the various sites. Organic and Inorganic Nitrogen contents were found to decrease with increasing depth across the various selected dumpsite in Ughelli Metropolis Delta State. In general, both organic and inorganic nitrogen in the selected domestic dumpsite were found to correlate positively with some soil physical and chemical properties. The experiment shows that dumpsite nitrogen contents of the study areas were greatly influenced by type of waste materials, presence of leachate, surrounding groundwater and environmental conditions.
