Abstract: The rapid advancements in drone technology have ushered in a new era of precision agriculture, offering innovative solutions for both crop and animal-based agricultural practices. This study begins with an overview of drone technologies, including the various types of drones and sensors used for agricultural tasks. It then examines the key applications of drones in monitoring crop health, precision spraying, livestock management, and disease surveillance. Drones in agriculture provides insights into the improvements in efficiency, cost-effectiveness, and environmental sustainability. The paper discusses emerging trends such as the integration of artificial intelligence, machine learning, swarm drones, and IoT technologies, all of which promise to further enhance the capabilities of drones in farming. Ultimately, the paper evaluates the transformative potential of drones in revolutionizing agricultural practices globally, while addressing key challenges related to adoption and integration. Furthermore, the paper explores the limitations of drone technology, such as regulatory constraints, high initial costs, and technical expertise requirements.

Abstract: With the increasing population, the demand for food products is increasing day by day. The agriculture sector is adapting to technological reforms of traditional processes to maintain a proper balance between the demand-supply relationship. The intervention of the technology is resulting in the enhanced productivity of the agricultural process, and at the same time, it is also helping in the workload management of the farmers. In the last two decades, unmanned aerial vehicles (UAVs) or drones have emerged as indispensable tools in modern agricultural processes. Drones and allied smart technologies are being used for a variety of applications in this sector. This work presents a comprehensive survey of drones in the agriculture sector. The latest trends in the usage of drones from agricultural viewpoints are discussed. The work emphasizes the drone’s architectures, sensor integration, and availability in the open market. Furthermore, the challenges associated with this technology are also outlined.

Abstract: This paper presents a mechatronic solution for monitoring the crops vegetation status. A data acquisition system containing different types of sensors (multispectral, temperature, plant height, GPS) is placed on a terrestrial mechatronic platform that is carried by a tractor or on an UAV (Unmanned Aerial Vehicle). The multispectral sensor offers information about the reflectance, for discrete wavelengths, necessary to compute the so called vegetation indices. They are correlated with the degree of development and plant health, thermal and water stress, pests, fertilizer need and so on. Knowing these information, a timely intervention is possible, allowing to supply water, pesticide and fertilizer in the proper quantity, at the proper time and in the precise place, leading to major economic impact and significant environmental protection. Geographical information are used for geo-referencing the acquired data, so that the thematic maps to be generated.

Abstract: This paper proposes an analysis of spectral monitoring processes of the crop vegetation status. In terms of the extensive implementation of precision agriculture, the performant agricultural management must ensure the monitoring of crop vegetation. In this context, determination and interpretation of vegetation indices, based on spectral data, plays a very important role. The performed research revealed the characteristics of monitoring the status of vegetation in order to obtain the necessary information, ie structure, actions and performances required to achieve an efficient system of monitoring the state of vegetation resources and to obtain the application maps for a precision crop management.precision crop management. This complex system ensures data acquisition and processing, thematic and application maps realization and decision generating on obtaining large productions and quality, on optimizing the economic profits, achieving of an integrated environmental protection and increasing of the sustainability of agricultural systems.

Abstract: According to the operator experiences, the variable rate fertilization system based on the fuzzy self-tuning PID controller is researched in this paper, which is driven by electrically and hydraulic system. This system solves the problem that the parameters adjustment of the traditional PID is difficult. The system model is presented and is simulated by using MATLAB/ SIMULINK toolbox. The simulation results shows that the fuzzy self-tuning PID control could obtain better dynamic response and achieve the expected control effects. In order to verify this control system performance, many experiments are carried on in the lab. The experiments results show that the variable rate fertilization system based on fuzzy self-tuning PID control has high control accuracy and could meet the control requirements of the variable rate fertilization in precision agriculture.

Abstract: To meet the requirements of a large-scale soil moisture monitoring system, this dissertation developed a new type of capacitive soil moisture sensor based on the detection and amplification of the singal peak-to-peak value named PA-1 sensor. PA-1 sensor was calibrated and evaluated under static laboratory conditions. A new type of soil moisture sensor named PA-1 is developed, which is based on the relationship between soil moisture and soil relative permittivity. Circuit design, operating features and exterior design of the sensor are introduced. PA-1 is calibrated in solution samples using the standard calibration method. Calibration experiment results show that PA-1 has a very linear measurement curve. The performance of PA-1 is studied and compared to the widely used Decagon Company’s EC-5 capacitive soil moisture sensor. Experiment results show that PA-1 has advantages of high sensitivity, low temperature drift, strong tolerance to electromagnetic interference and low power consumption. Keywords: sensor, Precision Agriculture, low temperature drift, low power consumption.

Abstract: This paper has analyzed the current application status of agricultural Remote Sensing and the situation of teaching practice of Remote Sensing in Geographic Information Systems (GIS) at length; and practically looked for their breakthrough point. On this basis, the paper constructs the frame structure of their combination preliminarily, making the teaching practice combine with the practical application, which allows for the finishing of the process of teaching practice as well as serving the society.
