Mapping and differences of soil physical properties

Popis výsledku v původním jazyce

Soil physical properties are of great importance for the evaluation of soil compaction or for soil conditions characterization. The latter option is important for the purpose of soil tillage machines. Field measurements were arranged in order to characterize the variation of soil physical properties within the plot. Two methods of soil physical characteristics evaluation were used: soil cone index and undisturbed soil sampling. Undisturbed soil samples were taken from 102 points in almost regular grid 6 x 6 m. Cone index was measured thrice in the each point. The maps of mentioned measurements were created and compared by using statistical methods. Penetration resistance generally copied soil bulk density but otherwise than expected. Nevertheless, the most important finding was that relatively very small changes of soil moisture content can influence penetration resistance regardless, or with minimal impact, of soil bulk density results.
