Abstract

This paper explores the evolution path of smart agriculture in China and its implications for the development of smart tobacco, aiming to advance the full-process intelligent transformation of the tobacco industry. It systematically sorts out the integrated application and development context of key technologies such as the Internet of Things, multi-source sensors and unmanned aerial vehicles (UAVs).The research shows that China has achieved remarkable results in the infrastructure construction of smart agriculture. As of June 2025, the internet penetration rate in rural areas reached 69.2%. Nevertheless, the sector still faced bottlenecks including insufficient detection accuracy of core sensors and poor generalization ability of intelligent decision-making models. With the deployment of agricultural large models such as Hongnong and Shennong 2.0, as well as the popularization of intelligent water and fertilizer systems, agricultural productivity has been greatly improved. The migration of these cutting-edge technologies to tobacco production has delivered prominent outcomes: multi-spectral monitoring via UAVs has cut the response time for tobacco field disease prevention and control by more than 30%, and the recognition accuracy of intelligent curing technology has exceeded 90%.On this basis, this paper constructs a framework for an integrated management and control platform for smart tobacco covering the whole industrial chain of seedling raising, field cultivation and curing, and establishes a supporting traceability system for tobacco leaf quality and safety. It is expected to provide theoretical references and technical approaches for the high-quality development of modern tobacco agriculture.

Smart farming solutions combine information, data software tools, and technology with the intent to improve agricultural production. While smart farming concepts are well described in the literature, the potential societal impacts of smart farming are less conspicuous. To demonstrate how smart farming solutions could influence future agricultural production, agri-business and rural communities and their constituents, this article compares smart farming approaches and reasons behind the pursuit of smart farming solutions by the U.S. and South Korea. The article compares agricultural assets and productivity among the two countries as well as the technical and societal challenges impacting agricultural production as a basis to understanding the motivations behind and pathways for developing smart farming solutions. In doing so, the article compares some of the technological and social advantages and disadvantages of smart farming, dependending on the choice and implementation of smart farming solutions. The South Korean government has implemented a national policy to establish smart farming communities; a concept that addresses the entire agri-food supply chain. In the U.S., a national plan to develop smart farming technologies does not exist. However, discrete smart farming solutions driven mainly by competition in the private sector have resulted in high-tech solutions that are advancing smart farming concepts. The differences in approaches and reporting of successes and failures between the two countries could facilitate the rate of evolution of successful smart farming solutions, and moreover, could provide pathways to facilitate sustainable development goals in developing countries where smart farming activities are currently underway.

The increasing contamination of soil with heavy metals, particularly cadmium, poses a significant threat to agricultural productivity, especially in tobacco cultivation. The primary objective of this study is to explore the impacts of biochar combined with microorganisms on tobacco resistance and soil remediation under cadmium stress. The experiment consisted of four treatments: namely, G0C0 (no cadmium or biochar added), G1C0 (cadmium 130 mg added, no biochar added), G1C1 (cadmium 130 mg added, 10 g kg−1 biochar added), and G1C2 (cadmium 130 mg added, 10 g kg−1 biochar added, and 1% microbial inoculant added). The influence of each treatment on tobacco growth and development, cadmium uptake by tobacco, soil biological characteristics, and components of soil microbial communities was investigated. The study revealed that cadmium stress had a negative impact on tobacco net photosynthesis. Notably, biochar was found to be effective in alleviating this effect. The results demonstrated that Apparent Quantum Yield (AQY), Maximum Photosynthetic Rate (Pmax), and Light Saturation Point (LSP) in G1C1 increased by 1.69%, 80.50%, and 30.76%, respectively, compared to G1C0. Similarly, AQY, Pmax, and LSP in G1C2 increased by 3.39%, 86.84%, and 62.35%, respectively. Following cadmium contamination, the levels of soil urease, catalase activity, and microbial biomass nitrogen and carbon were reduced. However, the application of biochar significantly enhanced urease and catalase activities by 12.42–63.89% and 13.03–14.17%, respectively. Additionally, the carbon and nitrogen content of microbial biomass increased by 46.42–76.27% and 21.56–28.12%, respectively, compared to the G1C0 treatment. The combined application of biochar and Trichoderma exhibited a synergistic effect, enhancing soil microbial diversity and community structure while increasing the abundance of beneficial genera such as Mucoromycota, Chaetomium, and Bacillus. Additionally, biochar effectively restricted the upward transport of cadmium in tobacco plants. These findings suggest that co-applying biochar and microorganisms offers a sustainable strategy to enhance tobacco plant resilience under cadmium stress, improve soil ecology, and promote soil remediation in contaminated environments.

Due to the challenges of pest detection in complex environments, this research introduces a lightweight network for tobacco pest identification leveraging enhancements in YOLOv8 technology. Using YOLOv8 large (YOLOv8l) as the base, the neck layer of the original network is replaced with an asymptotic feature pyramid network (AFPN) network to reduce model parameters. A SimAM attention mechanism, which does not require additional parameters, is incorporated to improve the model’s ability to extract features. The backbone network’s C2f model is replaced with the VoV-GSCSP module to reduce the model’s computational requirements. Experiments show the improved YOLOv8 model achieves high overall performance. Compared to the original model, model parameters and GFLOPs are reduced by 52.66% and 19.9%, respectively, while mAP@0.5 is improved by 1%, recall by 2.7%, and precision by 2.4%. Further comparison with popular detection models YOLOv5 medium (YOLOv5m), YOLOv6 medium (YOLOv6m), and YOLOv8 medium (YOLOv8m) shows the improved model has the highest detection accuracy and lightest parameters for detecting four common tobacco pests, with optimal overall performance. The improved YOLOv8 detection model proposed facilitates precise, instantaneous pest detection and recognition for tobacco and other crops, securing high-accuracy, comprehensive pest identification.

With the growing demand for efficient solutions to face the challenges posed by population growth and climate change, the use of unmanned aerial vehicles (UAVs) emerges as a promising solution for monitoring biophysical and physiological parameters in forage crops due to their ability to collect high-frequency and high-resolution data. This review addresses the main applications of UAVs in monitoring forage crop characteristics, in addition to evaluating advanced data processing techniques, including machine learning, to optimize the efficiency and sustainability of agricultural production systems. In this paper, the Scopus and Web of Science databases were used to identify the applications of UAVs in forage assessment. Based on inclusion and exclusion criteria, the search resulted in 590 articles, of which 463 were filtered for duplicates and 238 were selected after screening. An analysis of the data revealed an annual growth rate of 35.50% in the production of articles, evidencing the growing interest in the theme. In addition to 1086 authors, 93 journals and 4740 citations were reviewed. Finally, our results contribute to the scientific community by consolidating information on the use of UAVs in precision farming, offering a solid basis for future research and practical applications.

Selective agrochemical spraying is a highly intricate task in precision agriculture. It requires spraying equipment to distinguish between crop (plants) and weeds and perform spray operations in real-time accordingly. The study presented in this paper entails the development of two convolutional neural networks (CNNs)-based vision frameworks, i.e., Faster R-CNN and YOLOv5, for the detection and classification of tobacco crops/weeds in real time. An essential requirement for CNN is to pre-train it well on a large dataset to distinguish crops from weeds, lately the same trained network can be utilized in real fields. We present an open access image dataset (TobSet) of tobacco plants and weeds acquired from local fields at different growth stages and varying lighting conditions. The TobSet comprises 7000 images of tobacco plants and 1000 images of weeds and bare soil, taken manually with digital cameras periodically over two months. Both vision frameworks are trained and then tested using this dataset. The Faster R-CNN-based vision framework manifested supremacy over the YOLOv5-based vision framework in terms of accuracy and robustness, whereas the YOLOv5-based vision framework demonstrated faster inference. Experimental evaluation of the system is performed in tobacco fields via a four-wheeled mobile robot sprayer controlled using a computer equipped with NVIDIA GTX 1650 GPU. The results demonstrate that Faster R-CNN and YOLOv5-based vision systems can analyze plants at 10 and 16 frames per second (fps) with a classification accuracy of 98% and 94%, respectively. Moreover, the precise smart application of pesticides with the proposed system offered a 52% reduction in pesticide usage by spotting the targets only, i.e., tobacco plants.

Tobacco products are an addictive commodity. According to the World Health Organization’s (WHO) latest statistics data, tobacco kills more than eight million people each year. In 2003, the WHO proposed the Framework Convention on Tobacco Control (FCTC) to provide an effective framework for the control of tobacco products to governments around the world. In the field of tobacco products, the hardest problem is how to prevent counterfeit tobacco products and smuggling. To solve the problems, we proposed a blockchain-based traceable and verifiable logistics system for tobacco products with global positioning system (GPS) and radio-frequency identification (RFID) Technologies. In this research, we provide an overview of system architecture, and also define the protocol and the smart contract in every phase that stores data into the blockchain center. We realized a decentralized database and authentication system that uses blockchain and smart contract technology; every protocol in every phase was designed to achieve the integrity of data and non-repudiation of message. Every tobacco product’s shipping record will be completed by scanning the RFID tag and retrieving the GPS with a mobile reader, where the record will be updated and validated in the blockchain center. In the end, the security and costs of the system were analyzed, and a comparison was made with the EU’s (European Commission) method. Our system is more flexible for transportation, more secure in the communication protocol, and more difficult to tamper and forge data. In general, the proposed scheme solved the problem of tobacco products counterfeiting and tracking issues.
