methods of recultivation after the separation of wood and pasture considering
aspects of plant sociology, plant production and landscape planning have been
investigated on a site with siliceous soil and a site with limestone. The
assessment of the statistically exact trials included aspects of fertilizing,
questions about the selection of suitable seed mixtures and different methods
of seedbed preparation and -treatment.
In the year
after sowing, the vegetation cover reached a satisfying degree of about 70% on
both sites. The extremer soil and climatic site conditions, the more persistent
was the site specific mixture in comparison to the commercial seed mixtures on
the aspect of persistence, reproduction and cover.
site specific seed mixtures and the mixtures according to the seed law, no
difference in the biomass and energy yield could be observed, the quality
mixture ÖAG shows a higher yield than the other mixtures on both sites.
The use of
site specific seed mixtures caused a higher ecological value of the revegetated
areas. Fertilization at the beginning with organic long time fertilizer
supported a dense vegetation cover and ensured a high ecological function.
forest areas, useful and sustainable pastures with satisfying yields and high
ecological value can be produced if good preparation of the seedbed, the use of
high quality seed mixtures and an adapted fertilization are considered.
