    Union Catalogue of Agricultural Libraries in the Netherlands

    The WUR Library Catalogue contains bibliographic data on books and periodicals held by the libraries of Wageningen University and Research Centre and some 15 associated libraries. Holding data are added to each record.

    Subjects covered include Agrotechnology, Food and Food Production, Plant and Animal Sciences, Soil Science, Geo-information, Landscape and Spatial Planning, Water and Climate, Ecosystem Studies, Economics and Society.

    The joint collections of the participating libraries cover a substantial part of the internationally available scientific literature in these disciplines.

    As far as Dutch scientific literature in these fields is concerned, coverage can be considered near 100%, including much of the so-called "grey literature".

    All titles are entered in their original language. Keywords are added to facilitate subject searching.

    The database is updated every day and now contains over 830.000 records.

Extensive investigations into the biotic, edaphic and climatic factors of the growth site and timber production figures showed that Quercus borealis Michx.f. was a very useful hardwood species for the Netherlands, especially on well drained but moist sites. The great-adaptability of this species allowed culture also on less rich and drier soils. Q.borealis was less suited for the improvement of rundown soils or for maintenance of better soils. Other trees with a lower C/N quotient of the litter may be grown for this purpose, or be mixed with Q.borealis.

Red oak could only be sown in very dense stands and was unsuited for interspersing in other stands, especially if on poor and dry soils. Undersowing in stands of Scots pine was not satisfactory for soil maintenance. It would be useful if the purpose was to grow Q.borealis afterwards. This change must be in good time. Planting of Q . borealis was contrary to its growing requirements and growing qualities. Red oak should only be sown in very dense stands (1200-1500 litre acorns per ha); from the outset selective thinning must be consistently applied in these stands.
