Impact of 17-day stored human urine on soil physicochemical properties and growth of <i>Talinum fruticosum</i> in Agbor, Nigeria

This study investigated the effect of 17-day stored human urine on soil physico-chemical properties and the growth of Talinum fruticosum in Agbor, Nigeria. The experiment utilised nine 6-litre buckets of soil, with varying amounts of urine (360.10 mL and 620.10 mL) applied as treatments, and tap water used as control. Soil samples were collected and analysed before and after 30 days of plant growth for pH, sulphur, phosphorus, nitrogen, calcium, magnesium, potassium and other elements, along with cation exchange-capacity (CEC). Results indicated that the application of stored urine significantly increased the soil pH, nitrogen, calcium, magnesium and potassium levels compared to the control. The 620.10 mL of stored human urine improved the physico-chemical properties of the soil more than either 0 or 360.10 mL. The study concluded that 620.10 mL stored human urine could be a valuable organic fertilizer for enhancing soil fertility and plant growth, with the potential to improve agricultural sustainability in similar environments.
