The agricultural machinery is making a considerable negative contribution to the acceleration of global warming. In this study, we analyzed the impact of combine harvesters (CHs) on the global warming potential (GWP) by evaluating the telematics data from 67 CHs operating in Lithuania and Latvia between 2016 and 2020. This study examined the use of their technological operations and the associated impacts on ambient air and performed field tests using the same CH model to determine the composition of exhaust gases and the impact of different technological operations on GWP. The data confirmed the release of significant GWP during indirect operation, and it was estimated that considerable lengths of time were spent in idle (~20%) and transport (~13%) modes. During these operations, over 13% of the total GWP (~27.4 t year–1 per CH), affected by emissions, was released. It was calculated that a GWP reduction exceeding 1 t year–1 per machine can be achieved by optimizing the idling and transport operations. The dual telematics/field test data approach facilitates a comprehensive assessment of both the impact of CH exhaust gases on GWP and the methods for reducing the negative impact on the environment.

“…Modern harvesters with position sensors are able to calculate ideal cutting paths and can thus significantly reduce their operating time [127]. Automatic steering functions on combine harvesters, for example, lead to lower diesel consumption and an average reduction in air pollution of 0.6 t per year [128].…”

Agricultural production finds itself in an area of tension. As a critical infrastructure, it has the task of reliably feeding a growing global population and supplying it with energy. However, the negative environmental impacts caused by agriculture, such as the global loss of biodiversity and the emission of greenhouse gases, are to be reduced. The increasing use of digital technologies is often described as a panacea that enables sustainable agriculture. The relevant literature is very dynamic, but the large number of concepts and terminologies used makes it difficult to obtain an overall view. In addition, many contributions focus on presumed or modeled efficiency gains, but this ignores technical and societal prerequisites and barriers. Therefore, the aim of this work was to identify the opportunities and risks of smart farming (SF) for more ecological arable farming. For this purpose, a holistic and environmental view was taken. The potential of SF to aid in the reduction in the environmental impacts of individual agricultural work steps was examined via an analysis of current literature. In addition, rebound effects, acceptance barriers and political omissions were considered as risks that prevent the benefits from being realized. It was shown that SF is able to contribute to a significant reduction in the negative environmental effects of agriculture. In particular, a reduction in fertilizer and pesticide application rates through mapping, sensing and precise application can lead to environmental benefits. However, achieving this requires the minimization of existing risks. For this reason, a proactive role of the state is required, implementing the necessary governance measures.

“…"beater" threshing [10], which has a number of disadvantages. Those disadvantages include excessive power consumption [16], grain damage [17][18][19] and environmental pollution [20,21]. As per the author's investigation, no studies have been published on the systematic redesign and optimisation of a high-throughput, low-power-consuming and environment friendly, wheat thresher.…”

Threshing of wheat is a fundamental post-harvest operation to isolate grains from straw, leading to further processing and storage. This study introduces a promising and power-efficient technology named as "Compression-Oscillation" threshing, which relies on cyclic frictional squeezing rather than beating as in conventional threshers. Discrete element method simulation was used to model the physical characteristics of wheat spikes and grains as well as interaction properties such as bonding, coefficient of restitution, static and rolling friction. Concave clearance and rotor drum speed sensitivity were studied in terms of compressive force and threshing performance in the system. The achieved threshing efficiency is 98.0% at rotor drum speed of 350 rpm at concave clearance of 4.5 mm and throughput of 6 tons per hour. Results indicate that this technology could supersede the existing beater technology. Determination of wheat grain detachment strength, role of oscillation on the wheat grain bonding strength and development of full-scale commercial machine are suggested as future work.
