Traffic of harvester combines : effect on maize yields (Zea Mays L.) and soil compaction under direct sowing system
In this work, we quantified the effects of harvest traffic having different tyre ground pressures and axle loads on soil properties and maize (Zea Mays L.) yields. The treatments consisted of a control plot with no traffic (T1), a combine harvester with low tyre ground pressure (T2) and the same har...

| description |
In this work, we quantified the effects of harvest traffic having different tyre ground
pressures and axle loads on soil properties and maize (Zea Mays L.) yields. The treatments
consisted of a control plot with no traffic (T1), a combine harvester with low tyre
ground pressure (T2) and the same harvest traffic with high tyre ground pressure (T3).
Cone index (CI), soil water content (SWC), rut depth (RD), root dry matter per plant (RDM)
and maize yields (MY) were measured at seven places in relation to the tracks, namely:
centre of the tracks (0), and at 70, 140 and 210 cm on either side of them. For three growing
seasons, the results showed that in the topsoil (0 to 20 cm), CI values produced by treatment
T3 were > 2.7 MPa and between 3.4 to 4.25 MPa in the subsoil (20 to 60 cm). Also, when the
soil was trafficked by tyres with infaltion pressures of 120 to 240 kPa, the CI increased in the
topsoil and subsoil, but differences in rut depth (RD) at the surface did not extend into the
subsoil in terms of CI. The greatest differences in RDM were found in the third growing season.
The minimum MY of 4.7 Mg ha-1 was observed in 2016 (third growing season) in the centre
line of the tyre tracks after one pass of combine harvester with high tyre ground pressure.
Yield increased with distance from the track centres reaching 5.10 Mg ha-1 at 210 cm on
either side of them. The main conclusions were that one pass of the combine harvesters with
total weight load between 16.67 and 21.10 Mg was sufficient to increase the CI in both the
topsoil and subsoil layers while maize yields were significantly reduced by all compaction in
the combine harvesters tracks, as well as all positions alongside them. |
