    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.

Simulation of changes in nutrient concentrations around plant roots.
Factors determining nutrient uptake by plant roots can be divided into those influencing root geometry and root growth and those influencing the transport of nutrients to the roots. Experiments were carried out with maize on a nutrient solution in coarse sand and on mixtures of synthetic ion-exchangers onto which nutritive ions were adsorbed. The exchangers were used as a growth medium with characteristics between those of nutrient solution and soil.
The results from these experiments and especially from those with nutrient solution were used for computer simulation models (written in CSMP), describing the changes in ion concentration around roots caused by the uptake of nutrients and water by the roots as a function of time over long periods and more in detail over short periods.

To support researchers to publish their research Open Access, deals have been negotiated with various publishers. Depending on the deal, a discount is provided for the author on the Article Processing Charges that need to be paid by the author to publish an article Open Access. A discount of 100% means that (after approval) the author does not have to pay Article Processing Charges.

For the approval of an Open Access deal for an article, the corresponding author of this article must be affiliated with Wageningen University & Research.
