摘要：

Soil agrophysical. characteristics have been arranged into a certain hierarchy with respect to their importance for making agrotechnological decisions and setting up new tasks of field experiments. This hierarchy takes into account modern demands for information support of computer-based expert systems in the field of agrotechnology. Some aspects of spatial distribution of hydraulic properties of soils are discussed. It is recommended that the optimum number of replicates of their determination should be calculated with due account for their autocorrelation functions.
