ABSTRACT
The Mexican oregano “Lippia berlandieri Shauer” is a versatile plant, for multiple purposes
and high potential adaptative capabilities. To evaluate the possibility to use oregano
as a cover surface on tailings deposits and thereby mitigate the emission of particulate material with metals content, an experiment
was carried out comparing the plant growing rate over a period of six-month in four
substrates: tailings, vermicompost, “soil” of the region and a mixture of “tailings
plus vermicompost”. The statistical analysis shows a significant difference between
treatments, resulting in the “soil” substrate with the best performance,
followed by the mixture of “tailings plus vermicompost” treatment. The low permeability
of tailings strongly affects the adaptability and growth of the oregano plant; however,
the adaptation possibilities increase in the mixture of tailings with vermicompost
or “soil” of the region.
