    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.

After a discussion of the history of the regeneration methods in teak forests of Java since the end of the 18th century, and also briefly of that in India, regeneration systems for teak were reviewed: A. The Taungya system (in which field crops are grown between the rows of teak one year after planting); B. Growth from young seedlings (the number of seedlings can be increased before clearfelling); C. Interplanting with shade trees for weed control, physical improvement of the soil, erosion control and improvement of soil flora and fauna; if shade trees were leguminous, they improved supply of nitrogen; introduction of a second tree species, of which the best was Leucaena glauca; D. mixed regeneration (completely mixed in rows or in groups).

Descriptions of equipment and methods for the study include assessment of site quality and volume of commercial timber, geological and physical assessment of soil and soil flora. Thorough comparisons follow of 1) methods A and B, 2) method A with (~ A + C) and that without L. glauca, 3) method A with L. glauca (= A + C) and that with other indigenous species. Method A was much preferred to B, method A + C (with L. glauca) to that without L. glauca, and to that with other indigenous species. But close mixture with other indigenous species needed more research. The possibilities of plantations with more species deserved more attention.
