Evaluation of soil resources requires detailed study of all the factors that contributed to theirformation and realization that although these seem to be inexhaustible, they are limited in terms ofquantity and quality. This paper aims soil resources inventory and classification of Plain Aranca a veryimportant area in terms of overall economic and agricultural especially so based on accumulatedscientific support can be carried strategy and sustainable development of the projects. The studiedterritory has a single unit of relief, the plain, in the form of a large alluvial area of subsidence andramble, on which there are many abandoned streambeds, representing the old courses of the ArancaRiver and its tributaries. The influence and action in time of the pedogenetic factors (relief, rock, climate,hydrology), as well as the human intervention through the important hydro ameliorative works thatstarted more than two hundred years ago, determined the existence of a soil cover with a sharpcomplexity and diversity.
