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.
The greater part of the cost price of palm oil was spent on harvesting the ripe bunches. To harvest at the moment of best ripeness, the bunches had to be collected every 5 to 8 days.An oilpalm estate was divided in 8 divisions of approximately 2000 acres, under supervision of an assistant manager. Topografical differences in the divisions gave rise to very variable harvesting costs. Judging the cost price depended usually on common sense.On flat terrain the oil palms were planted in rows perpendicular to a railway line; on sloping terrain in widely divergent directions. The following labour analysis was drawn up: the labour effort of the harvesters to detect the ripe bunches; the labour effort to climb into the palm trees to cut off the bunches; the labour effort to carry the bunches to the railway; the labour effort to load the bunches into trucks. A formula was derived for the production per labourer. It represented a hyperbola for production per acre from 0 to∞and contained variables mainly dependent on topographic influences. Weather conditions and other influences explained the deviations from the most probable straight lines (reciprocals) and hyperbolae.
