Since the end of the 50's, a series of producer associations have been formed for working land in common in Spain, thus forming a new enterprise starting with small farms which were cultivated individually before. Usually two legal forms are applied to them: The Cooperatives and the Syndical Groups. The resulting type of enterprise can be situated, within the ample area of "group farming" as "cooperative farming," between "joint cultivation" and "collective farming," where the individual land rights of the owner are conserved. A true pooling of the lands are made, of the capital and of the work, giving place to alterations in the traditional order of agricultural exploitation, in the social as well as economic aspects.
