Answer:

Northern European Plain's excellent soil is called loess.

Explanation:

The European continent has varying deposits of loess soil from few decimeters to thick tens of meters. The Northern European countries whose soil predominantly loess are France, Poland, Germany, and northern Ukraine.  

The soil in this area is due to periglacial conditions. Loess results from built-up of wind-blown dust/silt that forms sedimentation. The silt particle is normally 20-50 micrometer in size that consists of less clay and a balanced quantity of sand and silt. It is homogenous soil which is also porous.

The present structure was formated by several steps, the first step was the collision of the Gondwana plate and Angara plate where the sea bed rose into longitudinal ridges and valleys, in the second collision step the Tethys bed rose greatly causing the final retreat of sea, forming the Great Himalayas and the Tibetan retreat of the sea. The third step was the formation of the lower Himalayas followed by the fourth step where the Himalayas ranges were elevated and the Sub Himalayas were raised. This last step led to the current structure of the Himalayas.
