Abstract

The complex spatial variation of environmental variables causes problems for adequate and affordable sampling, monitoring of temporal change, interpretation and mapping and obtaining information as input for mechanistic models. The Random Function model of spatial variation has proved useful for tackling these problems. Recent studies have identified limitations, while extending its application to a wider range of conditions. Other models of spatial variation have been proposed. These models must be evaluated, particularly in terms of their ability to generate cost-effective methods for collecting data to solve practical problems. The objective of this project are i) to identify the limits of geostatistics (Random Function) model of soil variation for practical problems, ii) To develop and extend alternative models of soil variation in space and time (e.g.wavelets, spatial point processes, state-space models, principal oscillation patterns,fuzzy regionalization etc.) iii) To evaluate these alternative models as a framework for sampling,temporal monitoring, interpretation, mapping and mechanistic modelling of soil and cognate information at different spatial scales. This work will proceed by the evaluation of alternative models of this spatial variation of real soil data, or data generated from models of soil processes.
