Abstract
AbstractQuantitative variations of shrinkage patterns in soil samples collected at different depths along a “V” shaped crack were estimated. Size distribution of cracks and size distribution of clods were also determined. Slight differences were found in the values of total shrinkage but at increasing depth cracks became larger and the number of dimensional size classes in which cracks were distributed increased. In samples collected at 0‐5 cm, and 25‐30 cm the largest cracks belonged to the dimensional class 0.8‐1 mm while in the deepest samples (65‐70cm) the width of largest cracks was 2.0 mm.Along the profile there was a regular increase of clods of the largest size (> 20 mm) from 25 %to more than 50 % for samples collected at the soil surface and those collected at 65‐70 cm, respectively.
