    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.

Nutrient elements applied to the soil not only give crop production but cause certain interactions with chemical constituents of the plant. Studies on four different plants, perennial ryegrass, sugar-beet, poplar and birch, demonstrated that regardless of difference in natural environment, each plant needed an optimum organic salt content as a condition to achieve optimum growth.

The total amount of organic salts present in tissue and the relative proportion of the individual organic salts could easily be influenced by application of certain nutrient elements. The total organic salt content required for optimum growth was about 1000 m-equiv. per kg dry matter for herbage of perennial ryegrass, 3500 m-equiv. in young leaves of sugar-beet plants, 1100 m-equiv. in poplar leaves and 550 m-equiv. in birch leaves.

The uptake of ammonium nitrogen led to decrease of organic salt content in plant tissue. This is probably not due to utilization of nitrogen in a plant but to competition between other cations and ammonium during nutrient uptake.
