Abstract

In conventional experimental design and analysis the effects of environmental variation are consigned to additive block, covariate or residual effects. This assumption may be plausible for classical trials conducted on plots within a single field, but is dubious if we wish to conduct experiments to compare the effects of treatments at the scale of a landscape. It is increasingly important to be able to do this to meet the requirements of policy makers. For this reason a model-based statistical framework, based on the geostatistical model, is proposed for the analysis of landscape scale experiments. Here treatments responses and contrasts are modelled as functions of location in space, and are estimated by kriging. This framework will be developed and then applied to a case study with relatively simple treatment structure, but responses likely to vary across the landscape.
