The decade of 1930 was marked by the economic depression that affected with particular virulence the Pampas agricultural. In this context, the conservatives that intervened the government developed the National Agricultural Census in 1937. This work is an exploration of the productive structure of Entre Ríos and its forms of commercialization based on the use of the census as the main source. To this end, the sizes of the productive units of each of the departments, the majority of the productions and their distance to the rail ports and exit roads will be studied in depth. Finally, this information will be crossed with the commercial dynamics of the ports of Entre Ríos. In sum, this work will seek to obtain a detailed image of agricultural production with the aim of problematizing about the consequences of the 1930 crisis in this territory.
