Spatial Variability Of The Soil Mechanical Impedance And Its Connection With Electrical Conductivity And Productivity Of Sunflower


Т. Yu. Bets

The spatial variability of soil mechanical impedance on the basis of scientific-research center of Dnepropetrovsk State Agrarian University has been studied. The horizon heterogeneity of the soil cover may be areas with reduced soil mechanical impedance on the north-east of the field, which are surrounded by homogeneous sites with higher soil mechanical impedance. Cluster analysis allowed identifying three main groups (clusters) with the same type of soil mechanical impedance change - A, B, C. The soil spatial organization groups (clusters) have been established as having statistically different physical and biological properties. It was found that the soil mechanical impedance can act as an integrated indicator that indicates spatial variability of soil physical properties.
