Quelques remarques concernant l'influence de la culture sur le développement du profil pédogénétique

The process of natural profile development, which is often to be brought to a standstill in cultivated soils, seems on the contrary to continue in a specific direction ( at least in many parts of Belgium). The effect of profile development in cultivated soils was studied in the Belgian polder area on sandy sediments, cultivated very soon after their deposition towards the VIIIth century. It seems impossible to classify these soils with one of the known Great Soil Groups of the temperate regions. It is thought that the described development in cultivated soils tends to change, although very slowly, the morphology of many of the Belgian gray brown podzolic soils on medium textured parent materials

De bodemgesteldheid van het Oudland van Veurne Ambacht

Belgian holocene marine deposits, similar to those in Zeeland, were surveyed. The formation of this area in south-west Belgium was associated with the Atlantic (Old Marine Deposits) and Subatlantic marine transgressions (Duinkerken I-III); in the Subatlantic Period sands and clays were deposited on the surface peat (dating from the Subboreal). The same distinction of the coastal area as in the south-west of the Netherlands could be made along the Belgian coast: Old Land, Middle Land and New Land soil landscapes, each with their own sedimentary and geographical history. Soils were classified according to this sedimentary history (physiography and morphology system), Soil formation in this area was closely correlated with hydrology, which governed decalcification.The relation between soils and crop production was studied (mainly field crops), using a method developed by Belgian soil scientists.The position of the settlements in relation to agricultural problems was described and measures to improve agriculture (manuring, treatment, drainage) were recommended.<p/
