Abstract:
The use of Nypa fruticans leaf ash and cow dung treatments at 10g, 20g, 30g and 10:10g, 20:20g 30:30g respectively for the remediation of hydrocarbon polluted soil at six replications each per 2kg soil was investigated at residual and cumulative treatment levels. Soil chemical property analysis indicated deficiency in nitrogen (N), phosphorus (P) and organic matter (OM) in polluted control, while soils amended with the respective treatments showed improvements in N, P and OM based on treatment levels, which may enhance the growth performance of indigenous microorganisms resulting in significant rate of degradation of hydrocarbon and mineralization of the soil. Soil total hydrocarbon content (THC) analysis indicated a significant reduction in the residual experiment, with 30g Nypa ash treatment showing the highest level of total hydrocarbon content (THC) degradation representing 57.90% reduction > 20g (57.74%) > 10g (57.56%), while the cumulative amendment with 30:30g Nypa ash + Caw dung showed the optimum degradation of 59.18%% > 20:20g (58.50%) and 10:10g (57.63%). This study has shown that the amendment of hydrocarbon polluted soil with Nypa fruticans leaf ash and combined treatment of Nypa fruticans leaf ash and cow dung may have the potential of effectively biostimulating the growth and performance of soil indigenous hydrocarbon degrading microorganism for optimum reduction of hydrocarbon pollutants.
