AGRICOLA

Intensive agricultural practices increase agrochemical pollution, particularly nitrogen (N) based fertilizers, which present an environmental risk. This study aims to evaluate long-term (2009–2020) data on soil water regime and nitrate dynamics at an agricultural experimental site on fine-textured soils and to better understand the implications of N management in relation to groundwater pollution. The field site is located in the Biđ field (eastern Croatia), in the proximity of the Sava river. Zero-tension lysimeters were installed at six selected locations. Lysimeters were used to monitor the water regime, i.e., outflows in which nitrate concentration was measured, while additional soil-water samples were collected via 4 and 15-meter-deep monitoring wells. Soil hydraulic parameters were estimated by combining the laboratory measurements, and estimation in RETC software. Water regime and nitrate leaching in lysimeters were simulated using HYDRUS-1D for each year to allow crop rotation and to evaluate their effects individually. The HYDRUS-1D model successfully reproduced lysimeter outflows and nitrate dynamics, which was confirmed with high R2 values (water: 93% above 0.7, and nitrate: 73% above 0.7) indicating the good performance of the model simulating nitrification chain reactions. Principal component analysis (PCA) was performed to identify the relationships among all soil properties and environmental characteristics. The results showed the complex interaction of soil hydraulic properties, precipitation patterns, plant uptake, and N application. All locations have a decreasing trend of nitrate leaching over the investigation period. Most of the lysimeter outflows and elevated nitrate concentrations were connected to the wet period of the year when the soil was saturated, and evapotranspiration was low. The results of this study show that it is important to optimize N fertilizer applications for each particular environmental condition to reduce nitrate loss. The study indicates the importance of long-term field studies, key for agro-hydrological modeling and the improvement of agricultural practices.

The main objective of this article is to analyse strategies of embodied cognition and the intersubjective ground for individual intentions in the process of image-based oncoradiology diagnosis. The article presents a range of both oncoradiology imaging specifics and concrete operations performed by radiologists during their daily professional routine. This data shows how the embodied diagnostic cognition based on medical imaging is structured. Hence, this paper proposes an enactive theory of oncoradiology imaging and considers the wider problem of how knowledge is related to the (embodied) subjectivity in a particular social setting.

The European Union (EU) is an integrated alliance of equally treated Member States sharing mutual values, legal principles and markets. Close cooperation, deep integration and convergence are the major priorities for the EU. Anyway, these principles are not always reflected in the EU-wide policies which are implemented through financial support mechanisms. The direct payments financial support mechanism under the Common Agricultural Policy, the main instrument for promoting convergence in development of Member States’ agricultural sectors and rural sustainability, faces critique for failing to meet its objectives. One of the major deficiencies of the direct payments scheme is that it allocates more resources to already developed agricultural sectors of the older Member States and less resources to developing ones thus increasing the divergence among the Member States. The aim of this paper is to suggest new mechanisms for direct payment funds redistribution across the EU Member States which are based on the methodological principles that would more precisely correspond to the aims of convergence, transparency and fair redistribution. The results show that, regardless of the method chosen (to support more or less effective agricultural sectors of EU Member States), the proposed methodology lowers differences in direct payment rates among the EU Member States by two-fold. This ensures correspondence to the goal of convergence within the EU.

Creation of a sustainable agricultural sector involves boosting the cooperation activities as these contribute to the societal and economic development of the farms, farmers and rural societies. This paper contributes to the literature on the analysis of the drivers and obstacles of cooperation development in agriculture. The case of Lithuania is considered as the cooperation activities are lagging behind the European Union (EU) practice here. Specifically, analysis of the public support measures and the expert survey are carried out to analyse the effectiveness of the public policy measures as represented in the relevant legal acts. The experts involve policy makers, farmers’ organisations and academia, which are the major stakeholder groups in Lithuania. The results indicate the effectiveness of the measures linked to capacity building (in the sense of human capital) requires improvement, whereas those related to financial support and promotion of the farmers’ organisations are much better perceived. Thus, public support measures are available to promote cooperation in agriculture, yet the legal system of Lithuania still requires improvement in accommodating effective agricultural cooperatives.
