    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 soil fumigation the concentration of the nematicidal compounds cis and trans 1,3-dichloropropene at various depths in the soil was estimated by electron-capture gas-chromatography. The coefficients for the distribution of the compounds over the phases in soil under various conditions were also measured. Differential equations were derived for the events during fumigation in the field. Combinations of analytical starting solutions and numerical solutions of these equations were used. With the computation models the dose patterns in soil under various conditions could be calculated. Of the weather related factors, soil moisture had the greatest influence on efficiency of fumigation. Large clods in the plough layer caused a shade effect in the dose patterns and a rough soil surface also decreased effectiveness. After careful application differences in effectivity for various types of fumigator were small. Most of the undesirable side-effects that appear after the waiting period can be prevented by fumigating in the favourable soil moisture range and by tilling to plough depth. Estimates were made of the relative importance of disappearance by volatilization, leaching and decomposition.
