Abstract:The objective of this study was to define and evaluate changes in distribution patterns of aggregate size distribution (ASD) and mean weight diameter (MWD) within a corn field following field traffic. The results indicated that the proportions of soil aggregates smaller that 4 mm significantly decreased and MWD increased from 5.23 to 12.46 mm after harvesting. Spatial distribution maps of ASD and MWD show that the effects of field traffic on ASD and MWD were more effective in the upper 15 cm layer. It was concluded that heavy field traffic produced higher fraction of aggregates larger than 4 mm which are not desirable because of a reduction in soil-root contact area and root penetration.
