“…There has been significant work done on soil compaction, yielding a deep and diverse published literature (Brevik, 2005). Some of this work includes the compaction effects of tillage (Le., Battikhi and Suleiman, 1999), logging and forestry (Le., Vora, 1988;Coder, 2000), grazing (Le., Van Haveren, 1983), recreational use (Le., Monti andMacKintosh, 1979, Stohlgren andParsons, 1986), how compaction affects crop growth (Tu and Tan, 1991), and how the soils in historic trails have (or have not) recovered from compaction (Sharatt et aI., 1998;Brevik et aI., 2002).…”

Soil compaction is one of the largest problems faced by modern mechanized agricultural and forestry operations. This makes research in the area of soil compaction critical. This study was undertaken to see how different types and levels of traffic have influenced soil compaction in sandy soils at the Valdosta State University Lake Louise field station south of Valdosta, GA. Four different traffic patterns were investigated in this study. The first area has relatively high vehicular traffic, the second more moderate vehicular traffic, and the third area a relatively low level of vehicle traffic. The fourth area has experienced foot, horse, and ATV traffic, but full sized vehicles like cars and vans have not been used in the area. To study compaction, soil cores of known volume were taken at the soil surface and at 30‐cm depths. These cores were taken both in the trafficked area (road, trail) and alongside the trafficked area at three locations for each treatment. Average soil bulk density values for the trafficked and untrafficked areas were statistically compared to determine the effects of traffic patterns on soil compaction. Results indicate that soils were more compacted along trafficked areas than in the corresponding untrafficked areas with the exception of the fourth area, which had experienced the lightest traffic load.

“…Measurements of PR presented in Table 1 show soil strength increasing from growth stage 5 (10 March 1998) to growth stage 16 (22 May 1998) due, primarily, to lower soil water and therefore to increased cohesion forces (Ehlers et al. 1983, Kemper and Rosenau 1984, Battikhi and Suleiman 1999, Sidiras et al. 2000), and, secondarily, to soil particle compaction (Materechera and Mloza‐Banda 1997, Pabin et al.…”

The root mass of winter barley (Hordeum vulgare cv. Niki) at growth stages 5, 9 and 16 of the Feekes scale increased from 100 % (0.272 mg cm–3 soil) to 132 % and 139 %, respectively. Root mass was always greater in no‐tillage (NT) plots than in ploughed‐tillage (CT) plots and was also greater where manure was applied in comparison to plots without manure. The root density at growth stages 5, 9 and 16 over all treatments was 0.197, 0.224 and 0.238 cm cm–3 soil, respectively. At growth stage 5, the root density in NT plots was 9 % greater than that in CT plots, and in rotary hoed (MT) plots it was 3 % greater. At this same growth stage, soil fertilization with NP, farmyard manure (30 t ha−1) and NP plus farmyard manure improved the root density of barley by up to 5, 10 and 11 %, respectively, in comparison with control plots. The diameter of barley roots was clearly biggest in CT plots, while in NT plots the thinnest roots were found. The mean diameter was 0.63, 0.75 and 0.78 mm at growth stages 5, 9 and 16, respectively (over all treatments). Significant correlation coefficients were found between root density (RD) and the soil properties bulk density (BD), porosity (P), penetration resistance (PR) and mean weight diameter of aggregates (MWD). For example, the highest r values were as follows: at growth stage 5, r=0.95 (P < 0.001) for P and r=0.86 (P < 0.001) for MWD; at growth stage 9, r=−0.97 (P < 0.001) for PR and r=0.96 (P < 0.001) for P, and finally at growth stage 16, r=0.97 (P < 0.001) for P and r=−0.97 (P < 0.001) for PR.

“…Differences in management can lead to changes in bulk density within a field or between fields that contain otherwise similar soils (Franzluebbers et al, 1995; Chen et al, 1998; Battikhi and Suleiman, 1999). Most of the compaction caused by agricultural traffic is in the upper 8 inches (20 cm) or so of the soil profile (Brevik, 2000; Brevik et al, 2002).…”
