    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.

The concept was rejected that in the Mediterranean and Euro-Siberian regions the class Rudereto-Secalinetea would consist of vicarious orders or alliances. The following views were presented:

The characteristic species of this class are indigenous and foreign adventive weeds. Its associations are made up of colonists. Most end their cycle within a year by natural succession (the indigenous associations) or by human influences (almost all adventive ones).

Because all these associations are adventive, nitrophilous, anthropogenous weed communities, they can be called domestic associations.

Four orders can be distinguished in the Netherlands. The Secalinetalia and the Chenopodietalia (formerly considered as one order) cover associations on regularly cropped soils tilled at least once a year. The Secalinetalia overwinter on most fields with autumn and early spring sown field crops; the Chenopodietalia occur in weeded crops. The Potentillo-Polygonetalia cover associations of rosette and tread plants on compacted substrates. The Onopordetalia occur on muck heaps, refuse and verges with nitrogen-rich substrates.

The floristic composition and the growth conditions of all associations were discussed at length.
