Abstract
The Someș Corridor, located in the central Transylvanian region of Romania, is a territory characterised by favourable conditions for habitation and land use with agricultural purposes, offering suitable premises for the development of the settlements and the economic activities taking place in the area. This study aims to identify the parcels of land from outside the built-up area, which can be used as arable land, this particular use being pursued due to the favourability induced by the pedological resources, the morphometrical characteristics of the Someș floodplain and, last but not least, the climatic conditions. GIS technology has been used, enabling the management of the databases representing soil, topography and climatic factors, and thus obtaining the classification of all land parcels using favourability classes for agricultural land use. In order to perform a correct favourability classification, the degree of soil pollution and groundwater pollution have been analysed, using chemical tests of water and soil profiles taken in the area of former abandoned industrial platforms, which are intended to be reintroduced in the local economic use. The highest degree of soil pollution with ammonium and sulphates has been identified in the industrial park from Dej city, on the territory of the former industrial platform of the paper factory, this pollution modifying the quality scores of arable land use, despite the fulfilment of favourable climatic and topographic conditions.

At this moment in Romania, in order to classify a specific territory according to its favourability for agricultural usage, one uses the methodology I, II and III of writing pedological studies, which regulates the required database as well as the intervals of each factor included in the analysis, that one may attribute the soil quality score for each crop and agricultural use
Using the GIS model for determining the suitability of the eight crops previously presented, average was computed to determine the classification of all the land parcels depending on their their average was computed to determine the classification of all the land parcels depending on agricultural use (Figure 6)
The present study uses a complex model of land analysis based on GIS spatial analysis using digital databases that represent the parameters for climate, soil and topography, which are taken into consideration for the identification of land suitability for agriculture
Summary
The capitalisation of agricultural terrains is included in the category of the objectives from the national strategic framework of Romania for the sustainable development of the agri-food sector.This strategic document mentions the fact that, in order to attain this objective, thorough research of the natural potential of the territory is necessary to fully capitalise on the areas with high potential.This would provide the necessary agricultural products for the internal use of the community, by efficiently applying an economic capitalisation on the territory, by preserving a sustainableAgronomy 2020, 10, 1245; doi:10.3390/agronomy10091245 www.mdpi.com/journal/agronomyAgronomy 2020, 10, 1245 ecological balance and, as much as possible, by preserving an acceptable degree of conservation of pedological resources.At this moment in Romania, in order to classify a specific territory according to its favourability for agricultural usage, one uses the methodology I, II and III of writing pedological studies, which regulates the required database as well as the intervals of each factor included in the analysis, that one may attribute the soil quality score for each crop and agricultural use.The main purpose of the present study is to identify the land surfaces with high favourability for agricultural use, in an area with a long history of implementing plant cultivation.

But not least, it is due to the facile access of all the categories of agricultural types of machinery used in the process of ploughing, amending and harvesting the products that are cultivated on the agricultural terrains
