It includes significant areas of gilgai microrelief, which is produced in clay soils that shrink and swell with changes in moisture content. |
Beaver impacts on the microrelief of canal slopes were examined in segments occupied by beavers for more than 10 years. |
Effect of tillage on fractal indices describing soil surface microrelief of a Brazilian Alfisol. |
A highly significant increase in the density of skin microrelief and a decrease of the deep furrows were demonstrated. |
Thus, variability appears to be related to fairly obvious systematic microrelief and morphologic differences, which must be taken into account during sampling. |
