    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

    We have a manual that explains all the features

Abstract At the request of the Global Soil Data Task (GSDT) of the Data and Information System of the International Geosphere Biosphere Programme (IGBP-DIS), ISRIC prepared a uniform soil data set for the development of pedotransfer functions. The necessary chemical and physical soil data have been derived from ISRIC's Soil Information System (ISIS) and the CD-ROM of the Natural Resources Conservation Service (USDA-NRCS). All soil samples were clustered into functional groups based on soil textural class and (calculated) activity of the clay minerals (9 classes), while samples from organic soils and allophanic soils were flagged. The digital set contains data for 131,472 samples, originating from 20,920 profiles. It is presented as a comma delimited ASCIIfile and in dBASE IV format. GSDT will use the data set to develop a number of pedotransfer functions for often required, yet seldom measured soil properties. Interaction with the global soil and modelling community led to the identification of four soil properties as being especially important and urgently needed: soil organic carbon, soil total nitrogen, water holding capacity, and soil thermal properties.
