Impact of the Technological Path on Some Soil Properties on Loess Slope

Edyta Kruk

Abstract

Investigations of horizontal and vertical changes of soil moisture and soil compaction on eroded loess slope, were the aim of the work. The study was performed on a farm in the municipality of Brzeźnica [N50°8’33,03, E18°13’16,31] (Province of Silesia, Poland). The research and collection of soil samples were carried out on 20.07.2017. On the day of the measurement, the slope was covered with winter wheat. Soil moisture and compaction degree were monitored at 36 points in the experimental area. The distance between the points along the slope were: 25 m (points: 1, 1a, 1b - 6, 6a, 6b), 50 m (points: 6, 6a, 6b – 11, 11a, 11b) and 200 m (points: 11, 11a, 11b – 12, 12a, 12b), while across the slope, the distances were 2 m apart. Vertical changes were determined based on measurements in depths: 0-5, 5-10, 10-15, 15-20, 20-30, 30-40, 40-50 and 50-60 cm. Soil moisture were carried out using device of the TDR HH2 type. Soil moisture was shaped between 2,8 and 28,0 %. The degree of compaction was determining using the Eijkelkamp manual penetrometer up to a maximum depth of 80 cm. The statistical analysis includes depths up to 30 cm. Soil compaction values between 0,24 and 2,66 MPa. There were high differences between values of examined parameters both horizontally and vertically in relation to location on the slope. Horizontal and vertical distributions of investigated parameters were elaborated using the analysis of variance, three-way, where independent factor were: road and location 2 and 4 m from it (factor A), depth (factor B), and position along the slope (factor C). Analysis of variance showed that in the case of compaction, there is a statistically significant effect of the technical path and distance from it, and depth, on the formation of this property. In case of soil moisture, the analysis of variance showed a statistically significant effect of the technical road and distance from it, as well as the depth, on the shaping of this property.
