Özet

Since essential oils are complex molecules containing different components, they also differ in terms of their biological effects. Many essential oils may have different antimicrobial effects depending on their active substance properties. This study was aimed to determine the composition of Liquidambar orientally. Mill. essential oil by Gas Chromatography/Mass Spectrometer (GC/MS) and to investigate the possible effects of different doses of this essential oil (1, 2 and 4 mL) on soil nitrogen mineralization at different temperatures (25, 28, and 32 degrees C). Soil Nitrogen mineralization was determined by the Parnas-Wagner method over 42 days (11th, 26th and 42nd days) at 25, 28 and 32 degrees C and under constant moisture (80% of field capacity). The major constituents of the oil were cis-Thujopsene (34.88%), Cedrol (25.05%) and alpha-Cedrene (12.48%). Both ammonification and nitrification of soils decreased as the temperature and dose of essential oil increased. While the highest nitrogen mineralization rate was in the control soils incubated at 25 degrees C (4.00%), the lowest rate was observed in the soils with 4 mL oil addition incubated at 28 degrees C (1.99%) (p < 0.001). Based on these results, it could be concluded that L. orientalis essential oil and temperature increase negatively affected ammonia and nitrate bacteria.
