Special Issue Information

Dear Colleagues,

Across the world, in every harvesting season, there are tens of millions of powered machine systems. Increasing efficiency and reducing fuel consumption are imperative to facilitate sustainable agricultural production. Innovative machine systems, processing and logistics, and technologies are needed to develop the next generation of engineered systems and sustainable agricultural products. There are many research and development activities used to improve exiting agricultural production systems. Furthermore, information system technology and automated control systems have been applied to field machine systems. The aim of this Special Issue is to collect related achievements in abovementioned areas.

The scope of this Special Issue includes the design and tests of field machine system performance, lab and field studies related to applied technologies in planting, harvesting, chemical application field practices, and post-harvest processing. Biomass harvest systems and logistics and bio-based product production systems are also within the scope of this Special Issue.

Manuscript Submission Information

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 submissions that pass pre-check are 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 250 words) can be sent to the Editorial Office for assessment.

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. Agriculture is an international peer-reviewed open access semimonthly 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 2600 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.

Automatic Section Control (ASC) promises to minimize spray overlap areas. The idea is to (i) switch off spray nozzles on areas that have already been sprayed, and (ii) to dynamically adjust nozzle flow rates along the boom bar that holds the spray nozzles when velocities of boom sections vary during turn maneuvers. Spraying and the movement of modern wide boom bars are highly dynamic processes with many uncertainty factors. Therefore, an Automatic Multi-Sections Control method is compared to a proposed simpler one- or two-sections alternative that uses a predictive spray switching. The comparison is provided under nominal conditions. Combinations of two area coverage path planning and switching logics as well as three sections-setups are compared. These differ by controlling 48 sections, 2 sections or controlling all nozzles uniformly with the same control signal as one single section. Methods are evaluated on 10 diverse real-world field examples. An economic cost analysis is provided. A preferred method is suggested that (i) minimizes area coverage pathlength, (ii) is suitable for manual driving by following a pre-planned predictive spray switching logic for an area coverage path plan, and (iii) and in contrast to ASC can be implemented sensor-free and therefore at low cost. Surprisingly strong economic arguments are found to not recommend ASC for small farms. Full article
