Prehistoric settlement activities changed soil pH, nutrient availability, and growth of contemporary crops in Central Europe

Background and aims How prehistoric human settlement activities have changed soil chemical properties, plant nutrition and growth of contemporary crops is a question that has not been satisfactorily addressed. The aim of this paper was to study to what extent nutrient availability in the soil, together with nutrition and growth of spring barley (Hordeum vulgare), improved on sites of former sunken buildings (cropmarks) in comparison to their surroundings (controls) 1,700 years after abandonment of the buildings.
