The agricultural crops within Oltenia occupy significant areas, especially at the level of the Oltenia Plain and of the Piedmont Hills. The rest of the areas where agricultural crops are located account for less extensive surfaces (at the top of the Getic Piedmont and of the Sub-Carpathian hills). In recent years, much of the agricultural land in this part of the country has been cultivated with precision agriculture, but in some areas conventional agriculture is still maintained. The comparative analysis of the lands where conventional versus precision agriculture is practiced highlights the existence of a different spontaneous vegetation, which on certain surfaces is harmful to agricultural crops. If we add to these the increasing recent expansion of invasive alien species, we can say that the production of these surfaces is significantly affected. Vegetation harmful to agricultural crops in Oltenia is included in 12 associations. The phytocenoses of the association Stellarietum mediae Hadac 1969 have the largest distribution, but the phytocenoses of the association Setario-Sorghetum halepensis Ștefan et Oprea 1997 cause significant damage.
