The significance of four soil treatments on basil growth and soil chemistry was analyzed at GC-MS: vermicompost (VC), bitmoss (BM) and VC+ sandy soil, and VC+ bitmoss. The GC–MS analysis determined that VC contained 29.2% stearic acid and 21.5% 2,4-dimethylphenol, and BM had a 20% humic acid. VC treated with 250 mL VC + sandy soil showed the highest positive influence on basil growth, resulting in the tallest (20 cm) and the biggest leaves (5 cm) were produced by the plants. In contrast, BM alone had slow growth response (5 cm) although being a product with humic acid for its fraction. The presence of BHT(T) (15.7%) in the VC + soil treatment indicated potential contamination. These results indicate that VC mixed with sandy soil provides ideal conditions for basil growth, possibly as a result of enhanced soil physico-chemical properties and nutrient availability.
