摘要

Essential oils, from aromatic plants such as oregano, have been reported to be efficient in controlling soil-borne pathogens and nematodes and therefore, could be used as pest control agents permitted in organic farming. In the present study, the roleof oregano on soil organic matter biodegradation was investigated together with its effect on mineral nitrogen and potassium and on organic phosphorus. Air dried oregano plant tissues at five rates (0, 100, 200, 300 and 400 mg/50 g soil) resulted in increases in mineral nitrogen forms and available potassium, with the higher rates of oregano, whereas organic carbon mineralisation and organic phosphorus were decreased. The addition of oregano at all rates resulted in a decrease in soil bacterial colonies.
