Abstract
The effect of petroleum hydrocarbon on soil environment contributes to low performance of microbes and plant yield. This study investigates the potential of grape leaf (Ponderosa lemon) on hydrocarbon constituents of crude oil contaminated soil. Freshly harvested grape leaf was washed thoroughly with tape water thereafter rinse with distilled water, some portions kept for room-dried and another for sundried to vary the composition. Fixed masses of loamy soil samples of 2000 g were mixed with masses of 100 mL crude oil with varying masses of grape leaf (biostimulant) of 50 g and 100 g in a plastic container. Some physicochemical properties were evaluated like pH, total organic carbon (TOC), total nitrogen (TN), phosphate (P), potassium (K), electrical conductivity (EC), heterotrophic utilizing bacteria (HUB), and heterotrophic utilizing fungi (HUF) for 42 days to determine the effectiveness of the biostimulant. The nutritional values of the remediants were quite promising as room-dried is composed of pH 6.74, TOC 8.95%, phosphate 0.891 mg/kg, TN 4.94 mg/kg, potassium 178.52 mg/kg, EC 28.63 𝜇𝑆/𝑐𝑚, HUB 2.4 × 102 cfu/g, and HUF 1.73 × 102 sfu/g. Sun-dried grape leaf follows same trend but still lower than the room-dried sample. The changes on the available nutrients for remediant subjected into sun-dried revealed that the bio-stimulant depletion was integrated to the potential effect of sunlight.
