    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.

Due to the increased use of dwarfing rootstocks and fertilizer experiments dressings increased from 90-120 kg N/ha in 1958 to 170-270 kg in 1965. In deciding on the quantity of nitrogen dressing its interacting effects on growth and fruit production as well as the influence of soil, weather and undergrowth were studied. Some of the experiments were carried out in pots, the others in the field.

The discussions cover the availability of nitrogen in the soil and the nitrogen requirements of the trees, especially in relation to competition with a full grass cover and grass strips. The system with grass strips and mulched bare tree strips is considered a case of fertilizer placement since the soil under the grass strip is extremely low in nitrogen during the greater part of the season.
