|
The roads' subbase originally consisted of no more than the clayey material excavated from the canals, and their asphalt wearing course was deeply cracked. |
|
It does not have particular edaphic needs as it can grow in soils of various kinds, such as clayey soils as long as they are sufficiently cool and deep. |

These nodules are always present in the southern part of the AFERNOD zone but further north coexist with nodule-facies B. The underlying silts are less clayey and richer in radiolarians. |
|
Compared with the second world war, which sprawled to the Asia-Pacific theatre, most of it was confined to one small, clayey corner of France and Belgium. |
|
Although the sands and clayey silts are very sensitive to erosion, these slopes are not very active, most likely because the high water levels, which play a crucial role in the erosion process, have disappeared. |
|
Besides, treating agricultural land with compost is known to increase soil-water retention especially in sandy and clayey soils and in desert areas. |

The 25-cm-thick shell-bearing interval consists primarily of clayey and very fine-grained sandy siltstone, with the dominant minerals being moganite and quartz. |
|
The soils are formed mainly of Devonian dolomite, dolomite marlstone, and clay bedrocks, moraine clayey material, sandy eolic and alluvial deposits. |
|
Most soils have been shown to be suitable for topinambur cultivation, though the soil should be siftable so excessively clayey soils should be avoided. |
