    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.

Application of slaked lime retarded growth of young tea plants on most soils in pot trials. Application of S, although beneficial to the growth of tea plants, had an adverse effect on the soil, when applied in large amounts. It lowered both the base saturation and the adsorption capacity of the soil. Therefore the

use of S on strongly weathered soils with a poor reserve of minerals could not be recommended. The injurious effect of applying S to slightly weathered soils with a sufficient reserve of minerals had no practical significance, since the adsorption complex impoverished of bases, enriched itself again by gradual weathering.

Another advantage associated with the use of S was that it seemed to control some parasitic root fungi of the tea plant, fungi which mainly occurred on slightly weathered young volcanic soils.

How far these results of pot trials would also hold for field conditions would largely depend on the thoroughness of mixing S and soil. In new plantations, S could be applied primarily to the plant holes. In nursery trials, however, S should be mixed with the whole top soil. The influence of base status of the soil on adult tea plants was not studied.
