Ordinary kriging assumes that the trend in the data is stationary, meaning it does not vary over space. This makes it the best choice when a scientific justification for a trend cannot be identified. Universal kriging, on the other hand, requires the specification of a deterministic trend model, which cannot be done without a scientific justification.
