Effect of wheel slip on soil compaction

The effect of the driving wheel of farm machinery at different slip rates on soil compaction was examined. The greatest values of soil bulk density and penetrometer resistance were found at the slip rate of 16.6%. The amount of surface sinkage in the soil increased with increasing slip rate. Variance analysis of the bulk density, penetrometer resistance and surface sinkage values showed that the effect of levels of slip rate was statistically different. -from English summary
