| Zusammenfassung |
| Season of seeding and soil amendment with manure mix, wood shavings and
erosion control blankets were evaluated over two growing seasons to
determine their effect on soil properties and native grass establishment at
a Canadian limestone quarry and lime processing plant. A season (fall, spring)
of soil amending and seeding did not significantly affect revegetation or
soil properties. Site characteristics such as slope, aspect, initial soil
nutrients and surrounding plant communities influenced early plant community
development and overall effects of soil treatments. Erosion control blankets
resulted in the highest seeded plant cover and the lowest non-seeded plant
cover despite not significantly changing soil chemical properties. Total
nitrogen and carbon significantly increased establishment of seeded grasses
and non-seeded species. Increased nitrogen and carbon in the constructed
soils were best achieved through addition of manure. Wood shavings did not
favour establishment of vegetation and resulted in similar, and in some
cases less, vegetation than the controls. Assisted revegetation increased plant
cover from < 6 to 50% and reduced cover of non-seeded species.
Amendments that modified both chemical and physical soil conditions were
best to increase vegetation establishment in the harsh conditions of the
quarry. |
