Soil pressure, deformation, and changes in soil physical parameters caused by beet harvester wheeling
In recent years, agricultural machinery became steadily larger and heavier. Especially under wet soil conditions, when soil is susceptible to compaction, heavy wheel load field traffic can lead to harmful soil compaction. This data set contains soil data from a wheeling experiment with an agricultural vehicle (3-axle sugar beet harvester). The experiment was conducted in 2016 on an agricultural test field in Adenstedt (Hildesheim district, Lower Saxony, Germany). The soil type is Stagnic Luvisol derived from Loess and was tilled with a cultivator up to a depth of 25 cm (reduced tillage). For the wheeling experiment, the harvester passed defined plots in the field with a full bunker (total weight: 62 t) and a half full bunker (total weight: 49 t). Maximum soil pressure and plastic soil deformation evoked by harvester passing was measured simultaneously with a multi-channel device consisting of Bolling probes (Bolling, 1987) and hydrostatic measuring hoses (Nolting et al., 2006). Maximum soil pressure and plastic soil deformation was measured in 20, 35, and 50 cm depth directly below the center of the tires. To investigate changes in soil physical parameters, soil structure, and soil functions caused by harvester driving, undisturbed soil cores (100 cm³) were taken before (unwheeled) and after wheeling (wheeled). Wheeling variants in the inner field area were sugar beet harvester with half full bunker and full bunker volume driving with all wheels in the same track (3 wheel passes). The wheeling variant of the headland area was sugar beet harvester with full bunker volume and multiple wheel passes in front of the sugar beet clamp. The sampling sites were located both in the inner field area and in the headlands. Two soil pits were sampled per wheeling variant in the inner field area and one soil pit in the headlands. A total of 30 undisturbed soil samples were taken per each soil pit, 10 per each soil depth (20, 35, 50 cm). The soil biopores were counted in every one of the three soil depths. 5 of the 10 undisturbed sampling rings were used to investigate soil water retention and the other 5 for saturated hydraulic conductivity. The determination of pF values was conducted in the soil laboratory using sand and clay boxes as well as pressure pots according to DIN ISO 11274. Saturated hydraulic conductivity was analyzed using a soil water permeameter (open system) according to ISO / FDIS 17312. The soil parameters, total pore volume, air capacity, field capacity, usable field capacity, permanent wilting point, dry bulk density, and current water content during soil sampling were derived from the soil laboratory results.
