Abstract:
Accidental petroleum hydrocarbon leakages or from other products
used in the petroleum extraction process represent an important pollution for
both the soil and the environment. The rehabilitation of fields used temporary
for the extraction of petroleum requires a series of measures and works based
on the soil’s physical-chemical properties. The present paper presents the
state of soils from three forest field surfaces located in Giurgiu County where
probes were installed. Currently, these fields are unrigged. The article then
focuses on the improvement and silvotechnical measures and works necessary
for the restoration of fields back to the forest sector to which they belong. In
most situations, these fields are deranged (excavated, levelled and battered),
polluted with hydrocarbons and saline water or with other products used in
extraction processes. The restitution of fields from drilling areas back to the
forestry circuit implies the application of specific technologies for preparing
the field and for improving the soil. This is complemented by the application
of special afforestation technologies based on the specific characteristics of
both field and soil. In the case of soils weakly-moderately polluted with
petroleum hydrocarbons, special rehabilitation or bio-restoration works are
necessary in order to obtain their afforestation. These works might consist in
mineral fertilisation, organic fertilisation, amendments or scarification.
