“…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]. According to Grisso et al [8], not every farm or field will reap a measurable economic benefit from VRA, but these technologies offer opportunities for growers to increase both the production and environmental efficiencies of crop production and should be carefully evaluated at the field scale in experiments that compare variable rate vs. uniform application.…”

“…Precision application of agricultural inputs strives to optimize crop profitability and sustainability by increasing yield and improving input efficiency while concurrently decreasing spatial and temporal variability and diminishing adverse environmental effects [8]. Many types of fertilizer ejectors are used in variable rate fertilization devices, including the outer-grooved wheel type, centrifugal type, vibrating type, and star wheel type [1], although the centrifugal disc spreader is by far the most common applicator for granule fertilizer in Europe [7]. This spreader type uses the rotating disk at the bottom to scatter fertilizer particles under the action of centrifugal force [1].…”

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.

“…Many enterprises and researchers around the world have conducted research on the intelligent control of targeted deep-fertilization machines for liquid fertilizer. The AT3000 deep-fertilization machine for liquid fertilizer developed by Blu Jet is equipped with an intelligent fertilization control system based on GPS/GIS [13]. When the machine is working, the system can adjust the amount of fertilizer in real time according to the prescription map information.…”

Given the problems of targeted variable deep application of liquid fertilizer in the field, such as low precision, inaccurate fertilization amount, and poor fertilization effect, a targeted variable fertilization control system of liquid fertilizer based on a fuzzy PID algorithm was designed in this study to realize the combination of precise variable fertilization technology and targeted deep-fertilization technology. Specifically, the fertilization equipment and adaptive fuzzy PID control strategy of targeted variable fertilization were designed first. Then, the mathematical model of the targeted variable fertilization control system of liquid fertilizer was established following the requirements of intertillage and fertilization of corn crops. Afterward, the response time and overshoot of the control system were simulated through the Simulink tool of MATLAB software, in which the fuzzy PID control and traditional PID control were compared. Then, the control effect of the targeted variable fertilization control system was verified through field experiments. The test results demonstrated that in the process of simulation analysis, the response time of the variable fertilization control system based on fuzzy PID control was shortened by nearly 5 s on average compared to the system based on traditional PID control, and the error was controlled within 10%. In the field test, the target rate of targeted variable fertilization equipment for liquid fertilizer reached more than 80%, and the control accuracy of the liquid fertilizer application amount also remained above 90%. Finally, the tracking experiment to check the fertilization effect proved that the targeted variable deep-fertilization method of liquid fertilizer could further improve the yield of maize crops under the premise of reducing the fertilization cost. The study provides a feasible solution for the method of precise variable fertilization combined with targeted fertilization.
