    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.

As soils differ in capacity to form a structure, it is necessary to distinguish between intrinsic structure and actual structure. Intrinsic structure is the capacity of a soil to form a certain structure. Actual structure is the structure of the soil at a certain moment.

Using experiments and published data, the factors that influence both structures were discussed. This study showed that it was necessary to distinguish between floc structure, microstructure and macrostructure as the successive states of aggregation. In soils with very low electrolyte content only microstructure and macrostructure could be distinguished.

A review was given on methods of estimating soil structure in the field and laboratory. Apparent discrepancies in the results of methods of estimating the structure of a soil were explained.

Finally water relations in soils with different structures were investigated with tensiometers.
