    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 investigation was carried out with Zea mays , grown under temperate conditions, and with Tripsacum laxum Nash, grown in the tropics. The conditions for nitrogen fixation were found to be unfavourable in the leachate, obtained by spray irrigation of the aerial plant parts of both experimental plants, but were favourable in the water present between sheath and stem. The ability of the phyllosphere micro-flora to fix nitrogen was proved qualitatively with the acetylene-reduction technique. The amount of nitrogen fixed by the micro-organisms in the phyllosphere of guatemala grass (260-400 g/ha per year) was estimated by exposing entire plants to 15N in situ. The nitrogen-fixing micro-organisms belonged mainly to the Enterobacteriaceae (genus Klebsiella).
