|Abstract||The geomorphology and soil conditions of some polders were studied, mainly consisting of sandy creek-ridge soils and marshy clay soils on peat (Old Land). Also a few New Land polders (Young sea clay) were surveyed.
Important soil characteristics were granular composition at different depths and water control, which govern suitability for crop growth. Soil series and types, present land-use and suggestions for soil improvement were reviewed and described. The results of studies on the requirements of fruit-trees on various soils were described. Data were collected from seven orchards, each uniform in planting and treatment, but with different soil conditions at short distances. Very detailed soil survey and watertable measurements were made and condition of fruit-trees (vegetative growth, settling, yields) was assessed. This method was called 'inferior site inquiry' being a method in land classification. Results showed great influence of soil conditions, permitting a provisional arrangement in three suitability classes and allowed some conclusions on the requirements of fruit-trees (apple, pear, plum, cherry and currant).
