The Castilla y León region
This area in the north of Spain has been object of interest as test site in recent years thanks to a collaboration with Instituto Tecnológico Agrario de Castilla y León.
The morphology of Castile and León consists, for the most part, of the northern half of the Meseta Central (Meseta Norte) and a belt of mountainous reliefs. The Meseta Central is a high plateau with an average altitude close to 800 metres (2,600 ft) above sea-level; it is covered by deposited clay materials that have given rise to a dry and arid landscape.
The main hydrographic network of Castile and León is constituted by the Douro river and its tributaries.
