Special Issue Information

Farming products are one of the most important categories in supermarkets. Large retail organizations are increasing their requirements concerning food safety and sustainability. The growing systems are characterized by an intensive and optimal use of land and water (agricultural exploitation is an industry itself). The common aim is increasing productivity and improving product quality.

In this context, a secure and environmental-friendly farming must be also part of this approach, the energy, water, nutrients and CO2, related to intensive growing systems or extensive systems must be considered to be basic given that they are related to the needs of the agricultural products. This demand is determined by an elementary process of mass and heat transfer involving a complex of physical, chemical, and biological processes, taking place simultaneously, reacting to environmental factors with different response times and patterns, and characterized by multiple interactions, which have to be controlled to obtain the best results for the grower.

This special issue will include articles that analyze the CO2 technologies applied to the agronomy from the economic, environmental and social points of view. Particular consideration is given (but not limited) to empirical articles that analyze the contribution to the vegetable production of new applications in market price analysis, studies of costs, economic, environmental and social considerations, efficiency, circular economy, precision agriculture, smart farming, automation, sensor technology, nutrients and waste management, life cycle analysis, production, storage and/or consumption of CO2, renewable energy and bioenergy. Anyway, the use mathematical models and control approaches will be welcomed.

Papers included in this Special Issue will address the following areas:

  • Smart farming and precision agriculture
  • CO2 storage, generation, uses, management and technologies
  • Carbon cycle
  • Life cycle analysis
  • Cost Management
  • On plant solutions
  • On biotechnology solutions
  • Automatic control
  • Modelling
  • Decision Support Systems, DSS
  • Circular Economy
  • Business models
  • Renewable energy
  • Residues management
  • Waste management
  • Sensor technology
  • Nutrients management
  • Value chain agri-food
  • Carbon Footprint

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agronomy is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

This work presents an alternative for adding value to greenhouse crop residues, used for (1) heating and (2) as a CO2 source. Both options are focused on greenhouse agricultural production, but could be applied to other applications. The influence of factors, such as the air/fuel rate and turbulence inside the combustion chamber, is studied. Our results show that for pine pellets, olive pits, tomato-crop residues, and a blend of the latter mixed with almond prunings (75–25%), the thermal losses ranged from 19.5–53.1, 20.5–58.9, 39.9–95%, and 29.4–75.5%, respectively, while the NOX emissions were 30–247, 411–1792, and 361–2333 mg/Nm3, respectively. The above-mentioned blend was identified as the best set-up. The thermal losses were 39.2%, and the CO, NOX, and SO2 concentrations were 11,690, 906, and 1134 mg/Nm3, respectively (the gas concentration values were recalculated for 0% O2). Currently, no other work exists in the literature include a similar analysis performed using a boiler with a comparable thermal output (160.46 kW). The optimal configurations comply with the relevant local legislation. This optimization is important for future emission control strategies relating to using crop residues as a CO2 source. The work also highlights the importance of ensuring a proper boiler set-up for each case considered. Full article
