Three wild species of aromatic plants (Thymus serpyllum 'minor', Lavandula stoechas L. and Myrtus communis L.) are studied over a one-year period and the results are compared with Vetiveria zizanioides L., a non-native grass. The study was carried out in Valenzano (Bari, Southern Italy), where soil loss and runoff were measured in an experimental set-up consisting of 9 plots, with size 1 x 6 m2 and 20% slope. The experimental runs were carried out using a rainfall simulator over the plots. The results obtained reveal that the downstream barriers are more efficient in reducing soil loss than the longitudinal rows. The tested plants show a decreasing efficacy from Thyme to Myrtle and Lavender.
According to the results obtained, vegetative barriers of aromatic shrubs could be used in combination with ordinary farming practices for a sustainable agriculture, which takes into account the environmental protection.(Download PDF) (Export to EndNotes)
