Productivity of Pine Plantations during Reclamation of Sand Quarries

چکیده
Restoration of lands disturbed by anthropogenic impact is currently the most urgent issue in light gradually decreasing area commercially valuable plantations. Reclamation quarries includes restoration artificial landscape carrying out various kinds measures. We have surveyed located northern districts Arkhangelsk region. These were used for sand mining construction roads federal and regional importance. No forestry activities carried one quarries. It was adopted as a control site abandoned to natural regrowth. Deciduous trees shrubs (birch, willow) some places grow there after decade half. In two other mechanical soil treatment seedlings Scots pine (Pinus sylvestris L.) planted. This species planting on sandy soils form productive stands. Studies shown that young stands second age class quality II, with average forest inventory values diameter 14.6 cm, height 15.6 m stock 168 m3/ha. The plants are healthy, physiologically developed annual increment 56 cm over last decade. Forestry measures effectively development quarries, firstly, provide necessary optimal conditions growth plants, and, secondly, biologically areas land surface formed due reclamation. territories an excellent reserve increasing covered vegetation.

Innovative Developments in Sand Reclamation Technologies
Reclamation of used moulding and core sands is defined as a treatment of waste refractory materials allowing to recover at least one component of properties similar to the properties of the new component and to reuse it for casting moulds and core production. In traditional technologies of casting moulds and core production on the basis of high-silica sands with binding agent addition, the recl...

in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Pine Plantations and New England Forestry
ORESTRY began to be promoted in New England only a little over a quarter century ago. In that period the federal Forest Service, the several associations, and later as they became established the state departments and forest schools have built up an immense campaign of education. This publicity has largely determined the popular conception of forestry and hence the direction of its growth. Almo...
متن کاملFertilization Increases Below-ground Carbon Sequestration of Loblolly Pine Plantations
The extent of fertilization of southern pine forests is increasing rapidly; industrial fertilization increased from 16,200 ha per year in 1988, to 344,250 ha in 1998. Fertilization increases stand productivity and can increase carbon (C) sequestration by: 1) increasing above-ground standing C; 2) increasing C stored in forest products; and 3) increasing below-ground C pools. This talk will conc...
