Special Issue Information

Dear Colleagues,

Crop and livestock production under agricultural buildings are among the most intensive agricultural systems. During the recent decade, several technologies and techniques have been developed and used to increase the sustainability and circularity of the above systems and cover the increasing demand for a high quantity of high-quality food, leading to higher intensification and industrialisation of the agricultural sector. Precision agriculture (PA) that aims to optimize and improve agricultural processes requires fast, reliable, and distributed measurements in order to give growers a more detailed overview of the ongoing situation in their farm area and control the automations of the production systems in such a way that optimises the use of inputs. Thus, production practices have been modernised by involving PA technologies, decision support systems (DSS), sensors, automations, and highly promising families of technologies such as the wireless sensor networks (WSN), the Internet of Things (IoT), and cloud computing.

Having collected information from animals and plants using many diverse systems and sensors, DSS and early warning systems based on smart algorithms included in cloud computing can be used to provide better insight into ongoing processes and make predictions about potential dangers that may threaten production. Accordingly, several research institutions in cooperation with the industry are working to deliver equipment and automations to the relevant stakeholders.

The goal of this Special Issue is to provide the members of a multidisciplinary community with a collection of manuscripts that present the latest innovative studies, tools, approaches, and techniques that have been successful in addressing some of the above concerns, such as the use of sensors and measuring and data analysis techniques, energy saving technologies, circularity increase techniques and methods and automations and control systems in agricultural buildings including greenhouses, screenhouses, livestock buildings, and facilities for agricultural products storage and drying.

Two experiments were conducted in different cropping seasons under Mediterranean climatic conditions to investigate the impact of two cooling systems (fan-pad evaporative as opposed to fan ventilation) on greenhouse microclimate and soilless cucumber growth. The second objective of the experiment was to determine the most appropriate irrigation regime (between 0.24 and 0.32 L m−2) in relation to crop water uptake and greenhouse fertigation effluents. The use of a fan ventilation system enhanced the vapor pressure deficit; thus, the crop transpiration improved by 60% in relation to the transpiration rates of plants grown under the fan-pad system. Higher transpiration rates alleviated the heat load as the external–inside greenhouse air differences declined from 6.2 °C to 3 °C. The leaf–air temperature differential indicated that plants were not facing any water stress conditions for both cooling systems tested; however, fan ventilation reduced drainage emissions outflows (95% decrease) compared with evaporative cooling. Results also demonstrated that an irrigation regime of 0.24 L m−2 can be applied successfully in soilless cucumber crops, keeping the drainage to a minimum (20% of the nutrient solution supply). These results suggest that fan ventilation cooling system in conjugation with an appropriate irrigation regime prevents overheating and minimizes the nutrient and water losses in spring-grown soilless cucumber crops in Mediterranean greenhouses without compromising yield.
