Assessing Farm-Level Digital Maturity in European Agriculture: The Digital Farm Index and Investment Barriers to Agriculture 4.0
(MDPI, 2026-07-22) Ailioaei, Claudiu-Ovidiu; Dumitraș, Constantin-Dragoș; Coca, Oana; Ștefan, Gavril
The transition toward Agriculture 4.0 aims to improve farm performance and sustainability; however, existing macroeconomic indicators do not fully capture the depth of farm-level digital adoption. This study proposes the Digital Farm Index (DFI) as a tool for assessing digital maturity and regional disparities in European agriculture. The research combines bibliometric mapping of the scientific literature with an empirical DFI assessment for 18 European Union Member States using Eurostat data. The empirical assessment utilizes multiple linear regression, log-linear scale modeling, and hierarchical clustering to analyze adoption patterns and structural determinants. The index integrates four dimensions: connectivity, precision agriculture, robotics, and farm management information systems (FMIS). Results indicate that adoption is concentrated in larger farms, as area-weighted digital maturity (DFI-Hectares) consistently exceeds farm-level adoption (DFI-Farms). CAPEX-based cost modeling suggests the existence of a technological indivisibility threshold, whereby digitalization may become an entry barrier for fragmented farms with limited economies of scale. Multiple linear regression suggests an East–West structural trend: while farm size influences the territorial diffusion of technology, a more consolidated regional innovation ecosystem appears more relevant for farm-level adoption. Findings also highlight a hardware–software imbalance and limited use of data-driven managerial tools. Support policies should therefore move beyond equipment subsidies and include technology transfer networks, digital skills, and managerial data-integration tools.

What Drives Renewable Energy Adoption in EU Countries? Evidence on the Differential Effects of Economic, Structural and Energy Factors
(MDPI, 2026-04-30) Andy-Felix, Jităreanu; Mioara, Mihăilă; Carmen-Luiza, Costuleanu; Alina, Mărcuță; Liviu, Mărcuță; Valentina Constanța, Tudor; Marius Mihai, Micu; Iulia Diana, Arion
The transition to renewable energy is a central objective of the European Union’s energy and climate policies, yet adoption rates differ significantly across Member States. This study analyses the economic, structural, and energy determinants of renewable energy adoption in the EU-27 over the period 2008–2023, using panel data models with country and year fixed effects and clustered standard errors. The results indicate that the relationship between renewable energy and its main determinants is limited and heterogeneous across countries. Most explanatory variables do not exhibit consistent and statistically significant effects across model specifications. In particular, research and development expenditure does not show a robust impact, while GDP per capita is associated with negative coefficients in several specifications, suggesting the presence of structural constraints and path dependency. Energy-related variables also display weak and unstable relationships. The findings suggest that renewable energy adoption is shaped by context-specific and heterogeneous dynamics rather than by uniform drivers. The study contributes by highlighting the limited explanatory power of standard macroeconomic indicators and supports the need for differentiated policy approaches across Member States.

Field Performance and Wear Behavior of Atmospheric Plasma Spraying (APS) Coated Discs Used in Agricultural Disc Harrows
(MDPI, 2026-01-01) Arsenoaia, Vlad-Nicolae; Munteanu, Corneliu; Lupu, Fabian-Cezar; Istrate, Bogdan; Benchea, Marcelin; Melnic, Iurie
The wear performance of coated and uncoated harrow discs was evaluated under real agricultural field conditions in order to assess the long-term effectiveness of three atmospheric plasma spraying (APS) systems: a Cr2O3–SiO2–TiO2 ceramic coating, a WC/W2C–Co carbide coating, and a Co–Cr–Ni–W–C alloy coating. In contrast to most previous studies focused on laboratory testing or short-term trials, the present work provides a comparative long-term field evaluation over 50 ha per disc (1000 ha total) under identical operating conditions in quartz-rich Argic Luvisol soil. Disc wear was quantified through periodic mass-loss and diameter measurements, complemented by microstructural and SEM analyses. The uncoated disc exhibited the most severe degradation, with a total mass loss of approximately 700 g and rapid acceleration of wear after the first 5–10 ha. The ceramic-coated disc showed the highest durability, limiting mass loss to approximately 390 g, corresponding to a reduction of about 44%, and maintaining the largest residual diameter after field operation. The Co-based alloy provided intermediate performance (~16% mass-loss reduction), while the carbide coating showed limited improvement (~7% reduction) due to microcracking and weak carbide–binder interfaces. The results demonstrate that, under real field conditions, coating microstructural integrity is more critical than nominal hardness, and highlight the superior effectiveness of ceramic APS coatings for extending disc service life in abrasive agricultural soils.

Improving the Microstructural and Mechanical Properties of Agricultural Ploughs Through Atmospheric Plasma Spray (APS) Thermal Coatings
(MDPI, 2026-07-21) Lupu, Fabian-Cezar; Munteanu, Corneliu; Bogdan Istrate; Ianuș, Gelu; Marian, Grigore; Boris, Nazar; Marian,Teodor; Benchea, Marcelin; Arsenoaia, Vlad-Nicolae
This paper presents experimental investigations carried out on components belonging to agricultural plough assemblies, which undergo significant mechanical loading during soil tillage operations. Due to severe operating conditions, ploughs are subjected to abrasive wear and impact stresses, so that enhancing these properties translates into improved performance, accompanied by a lower failure rate and, consequently, reduced downtime in agricultural activity. In order to upgrade the material properties of the active parts that come into direct and sustained contact with the soil—and which are therefore most vulnerable to degradation—surface thermal coatings were applied by means of Atmospheric Plasma Spray (APS) deposition, with the aim of extending service performance and component lifespan. The mechanical properties of the deposited coatings were assessed through hardness testing (approx. 204 HV) and microscratch behaviour evaluation (COF > 1). In addition, microstructural examinations were conducted using scanning electron microscopy to characterise the surface condition following the thermal deposition process. The findings confirm that thermal coatings represent a viable technical solution, enabling not only the improvement of plough component properties, but also the possibility of reconditioning worn parts by compensating, through thermal deposition, for the material loss caused by soil-induced wear during field operation

Social Media Use, Health Behavior and Body Appreciation Among Romanian University Students
(MDPI, 2026-07-10) Panciuc, Șerban-Laurențiu; Mihăianu, Iustina-Gabriela; Colibaba, Lucia-Cintia; Iorga, Magdalena
Background: In contemporary society, marked by rapid transformations in the sphere of communication and social interaction, social networks have gone beyond the role of simple communication platforms, becoming places where identities are formed, cultural norms are negotiated and self-perceptions are shaped. This reality has generated a growing interest in studying the relationship between the digital environment and health behaviors, especially among young people, a social category extremely receptive to visual and normative influences promoted online. Methods: A cross-sectional study was conducted among students enrolled in different kinds of faculties and specialties. An online questionnaire was distributed to gather socio-demographic, academic and medical data along with lifestyle and health-related behaviors. Several psychometric instruments were used: Health Behaviour Scale (HBS) to measure various dimensions of health-related actions, Bergen Social Media Addiction Scale (BSMAS) to screen for addictive or problematic social media use, Social Media Disorder Scale (SMDS) to measure the problematic social media use among adolescents, Body Appreciation Scale–2 (BAS-2) to evaluate measure of one’s acceptance, favorable opinions and respect of their own body, and Dutch Eating Behavior Questionnaire (DEBQ) to identify the psychological motives behind overeating. Results: More than 70% of students declared that they had their first smartphone before the age of 12 and 65% of students had screentime higher than 3 h per day during the weekdays, with a small increase during the weekends. Women scored higher than men in emotional eating (food consumption in response to negative emotions), and external eating (response to food stimuli in the environment, independent of hunger). Respondents from rural areas showed a significantly lower level of respect and acceptance of their own body and higher risk for Social Media Disorder compared to participants from urban areas. Important statistical correlation has been identified among the variables of the research. Social media addiction was associated with higher emotional eating both directly and indirectly, via lower body appreciation. The analysis also indicated that it does not show a direct relationship with restrictive eating behaviors; rather, its association with restrained eating is fully mediated by the individual’s body appreciation. Conclusions: The use of social platforms is a challenging process, with a great impact on psychological and emotional balance of young people. Even if the study identified a normative use among young people with a high education level, the risks factors should be taken into consideration when dealing with screentime, psychological and mental health and the risk for addiction.
