Aim. To investigate structural composition (lumpiness), bulk density and penetration resistance in soils of Polissia, Forest-Steppe and Steppe. Methods. The experimental plots were allocated on the fi elds in a regular network. The measurements performed before harvesting testifi ed to an equilibrium condition of soil physi- cal properties. The data ware processed by the geostatistical method. Results. The key parameters of spatial heterogeneity (variation factors, histograms, autocorrelation fu
