Zadorozhnaya, Galina
This article examines changes in the spatial distribution of soil penetration resistance in ordi- nary chernozem (Calcic Chernozem) and in the recultivated soil in 2012 and 2014. The meas- urements were carried out in the field using an Eijkelkamp penetrometer on a regular grid. The depth of measurement was 50 cm, the interval was 5 cm. The indices of variation of soil penetration resistance in space and time have been determined. The degree of spatial depend- ence of soil penetration resistance has been determined layer by layer. The nature of temporal dynamics of soil penetration resistance of chernozem and technical soil has been described. A significant positive relationship of the structure of chernozem in the two years of the research has been shown. Significant correlations between the data of different years in the technical soil were found to be mostly negative.
