Abstract
Information on the soil of any region is never free of error because it is derived from imperfect measurements, imperfect models and imperfect mapping algorithms. Scientists and technologists who produce the information and those who use it cannot be certain about the true values of the soil properties and soil classes in a region, and they must acknowledge the fact. That uncertainty can best be characterized by probability distributions. Geostatistics, based on such distributions, has become fashionable in the last 30years or so for quantifying uncertainty in spatial information, and rightly so as it quantifies the uncertainty in its predictions. Uncertainty in soil information also propagates through agronomic and environmental models. It must be communicated to end users because the validity of their decisions depends on it.
