STUDY ON THE STORAGE INFRASTRUCTURE OF CEREALS AND TECHNICAL PLANTS IN SOUTHWEST OLTENIA 2016–2023

Abstract

This study provides a comprehensive analysis of the evolution of cereal and industrial crop storage infrastructure in the South-West Oltenia region during the period 2016–2023. The research adopts a dual perspective, examining both the quantitative expansion of storage capacity and the qualitative improvement of storage conditions. Drawing on statistical data from Submeasure 4.2 of the PNDR 2014–2020, the study evaluates storage density per hectare, the number and geographical distribution of facilities, as well as the allocation of eligible and public investments. At the same time, it investigates how different construction materials—wood, reinforced concrete, metal, and polyethylene (silo bags)—influence the technological performance of storage systems by affecting durability, microclimatic stability, operational flexibility, and overall economic feasibilityThe results point to a visible intensification of investments, with total storage capacity increasing by 12% in 2023 and the number of facilities rising by 6%. Nevertheless, important territorial asymmetries remain evident, as counties such as Dolj and Olt continue to attract the majority of projects, while other areas remain underserved. Material-based analysis reveals that wooden structures are still present in small-scale contexts, reinforced concrete provides durability but limited adaptability, metal silos deliver superior long-term quality control, and silo bags represent a cost-effective and flexible short-term option.The discussion underscores that reducing post-harvest losses and achieving regional food security depend not only on expanding infrastructure but also on enhancing the technological and material quality of storage facilities.
