THE STATE-OF-THE-ART IN PEDOMETRICS

This paper briefly reviews the state of knowledge of the spatial and temporal variation of soil as discussed in the rejoinder session of the Pedometrics Workshop held in Wageningen, 1-3 September 1992. The paper discusses three aspects, namely theory, applications. and tools, in terms of current understanding and the research topics that we should be investigating in the next few years. Future directions for the study of soil variability are discussed in terms of issues for soil survey, issues for modelling, issues for methods and procedures, and finally, issues for effective communication of information about soil variability to users of soit data. An appendix of currently available geostatistical software is also included.
