“…Fertilizer has provided balanced nutrition and improved soil chemical and physical properties. Precision fertilizer application is an effective way to increase crop yield and quality [1]. Granular compound fertilizer, which contains nutrients such as N, P 2 O 5 , and K 2 O and is adaptable for mechanized fertilization application, is widely used in agricultural production.…”

The discrete element method (DEM) is an effective tool for obtaining qualitative and quantitative information on particle motion, which aids in the design and optimization of agricultural equipment structures. The accuracy of the DEM simulation parameters significantly impacts the simulation results. This study employed a combination of high-speed camera measurement, DEM simulation, and validation tests to determine the material and interaction property parameters for fertilizer particles. The basic parameters (triaxial size, bulk density, density, and coefficient of static friction) and coefficients of restitution between fertilizer and material were measured for three fertilizer varieties. There was a significant difference in the angle of repose between various material plates and fertilizer particles. The calibration values of coefficients of restitution and coefficients of rolling friction between fertilizer particles were optimized using the Box–Behnken method. The angle of repose was significantly affected by the coefficient of static friction and the coefficient of rolling friction between the fertilizer particles. The determined values for the coefficient of restitution, coefficient of static friction, and coefficient of rolling friction between the fertilizer particles were 0.323, 0.381, and 0.173, respectively. The error in the angle of the repose test was less than 3.0%, and the variation coefficient for each row consistency was less than 1.68 percentage points under the optimal simulation parameters. DEM simulations of the angle of repose and each row consistency variation coefficient test using the measured parameters can accurately predict the experimental results. The findings of this paper provide a theoretical basis for the DEM study of fertilizer particles.

“…PA cycle can be summarized in three main phases: (i) surveying soil and crop spatial variability; (ii) processing data and defining differentiated management zones; and (iii) making decisions and implementing differentiated soil, crop, and production system management [5]. In this generic structure, variable rate application (VRA) represents the closing of the cycle and is a technology commonly used for the application of agricultural inputs (seeds, fertilizers, and water) according to the actual requirements of different management zones delineated in the field [6]. This is a popular technique that optimizes and matches the inputs to the condition of the growing crops [7].…”

“…The two VRA systems currently available in the market for agriculture input applications are map-based variable rate technology (VRT with postprocessing control) and sensor-based VRT (with real-time control) systems [4]. The choice between these systems depends primarily on the type of application required but also on the investment policy and the level of technical know-how [6]. The main advantages of the map-based systems are related to the simultaneous application of multiple sources of information, the existence of application systems for most agricultural inputs, and the existence of a delay between input sampling and application, which can be helpful in improving system accuracy.…”

“…Providing these farmers with the right tools to mitigate adversity and to gain greater control of the production process could unlock their potential and support rural communities to meet the increasing global food demand [10]. Effectively, VRA provides the opportunity to improve the economic and environmental dimensions of agriculture [6]. This upgrade to VRT, the basis of the VRA concept, when compared with uniform application, offers a sustainable, efficient, and cost-effective solution for fertilizer application [4].…”

Over the last two decades, a considerable amount of equipment has been acquired (spreaders, seeders, sprayers, among others) to respond to the challenges of the precision agriculture (PA) concept. Most of this equipment has been purchased at a high cost. However, many of them, despite still being functional and equipped with sensors, actuators, and electronic processing units capable of adjusting to variations in speed, have become obsolete in terms of communication and incompatible with new monitoring and control systems based on the “Isobus” protocol. This work aims to present a solution for updating the control system (“Ferticontrol”) of a “Vicon RS-EDW” spreader with variable rate application (VRA), making it compatible with the “InCommand” system from “Ag Leader”. The solution includes serial protocol mediation using low-cost tools such as “Arduino” and “Raspberry Pi” microcontrollers and open-source software. The development shows that it is possible to implement a solution that is accessible to farmers in general. It also provides a niche business opportunity for young researchers to set up small technology-based enterprises associated with universities and research centers. These partnerships guarantee permanent innovation and represent a decisive step towards modern, technological, competitive, and sustainable agriculture.
