When we talk about technology and innovation in agricultural machinery, the quick answer to the current picture is: we have gone from raw mechanical strength to data-driven precision. Today, applying technology in the field does not mean just buying a tractor with a more powerful engine.It means using computers, sensors and software to ensure that machines apply seeds, fertilizers and pesticides in the exact amount and in the correct place. The practical result is the reduction of input costs and the increase in yield per hectare.

The current machines work as mobile data processing centers. By understanding how these technologies operate in the day-to-day of the farm, it is easier to justify investments, plan the training of the team and avoid the common failures of those who buy advanced equipment, but use only its basic functions.

You have probably heard the term “embedded technology”. In the daily practice of the farmer, this refers to the set of factory electronics that allow the machine to understand the environment around it and make decisions or assist the operator in making them.

Sensors and real-time data collection

Today's tractors and harvesters have dozens of sensors scattered throughout their structure.They monitor everything from basics such as engine temperature and oil pressure to complex information from the external environment.

There are systems capable of reading soil compaction as the tractor moves, meters that assess the moisture of the straw or grain at the time it enters the machine, and integrated weather sensors that block the application of pesticides if the wind speed is above the safe limit.

The jump of GPS and autopilot

The use of GPS in agriculture is nothing new, but the accuracy has changed dramatically. We left the old light bars, which only indicated the direction for the operator, for autopilot systems allied to RTK (Real Time Kinematic) networks.

With RTK, the positioning error of a tractor falls to margins of 2 to 3 centimeters. This ensures traffic control in the crop: the machine passes exactly in the same track every year. The trampling of the crop is avoided, soil compaction in the planting areas is reduced and the overlap of lines ends, which generates a direct saving in the purchase of seeds and fertilizers.

Agricultural machinery plays a crucial role in the modernization of agriculture, increasing the efficiency and productivity of crops.In addition, it is important to consider the interaction between agricultural technology and animal nutrition, especially with regard to ruminants.To better understand how the digestive system of ruminants influences agricultural production, you can read the related article on the importance of this system in the The Importance of the Digestive System of Ruminants.

Commercial automation: reducing losses in planting and spraying

The state-of-the-art technology makes the tractor-attached implement no longer a passive piece of iron and an active part of the production system.

Smart seed distributors and section cutting

In modern planting, planters have independent electric or hydraulic motors in each row.The system understands when the machine is passing through an area that has already been planted & common in embroidery pitches or irregular areas & automatically turns off the fall of seeds and fertilizers line by line.

In addition to the automatic shutdown (section cutting), there is planting at variable rate. The agronomist climbs a prescription map on the tractor monitor, informing that the most fertile area of the stand supports more seeds, while the weaker area needs less. The planter reads the map through GPS and changes the amount of seeds that are falling into the ground in real time, without the operator touching a button.

Localized spraying and weed reading

Traditional spraying covers the entire crop, regardless of where the problem lies. New technologies change this approach with systems equipped with cameras and optical sensors on the spray bar.

These machines can differentiate the color of the earth from the color of a plant (4“verde system in the brown”) or, even more advanced, can differentiate the main crop of a weed (4“verde system in green”). Embedded artificial intelligence processes the image in milliseconds and triggers only the exact nozzle that is on the weed. This can reduce herbicide use by more than 70% in some direct applications, decreasing the heavy operating cost and impact on the soil.

Modern harvesters: real processing plants

Harvesting is the time to put all the work of the crop to the test. Innovations in current harvesters aim to prevent part of this effort from being thrown on the ground due to regulation errors.

Automatic adjustment during operation

Previously, the operator tested the machine and adjusted the cylinder speed, sieve opening and fan rotation. As the temperature and humidity of the day changed, the grain could begin to break or be expelled along with the straw.

Today, harvesters use high-definition cameras in grain elevators and loss sensors in sieves. If the machine detects broken grains or impurities in the tank, it itself makes mechanical microadjustments in the sieves and concave to correct the problem automatically. The role of the operator becomes to monitor the system, and no longer perform constant mechanical stress.

Productivity mapping and future vision

While harvesting, the machine generates colorful productivity maps, creating a historical record of how many bags per hectare each square meter of the farm yielded. This map is the starting point for the next year.By crossing the harvester productivity map with the soil analysis maps, the producer understands exactly the points of chemical deficiency of the land, directing the soil correction efforts for the next crop surgically.

Communication integration: ISOBUS and data flow

So much technology created a problem in the early 2000s: the tractors of one brand did not talk to the planter of another. The cabin was crowded with different monitors hanging from the windows.

Global standardization through ISOBUS

To solve the conflict between brands, the industry has implemented the ISOBUS standard. This technology works like the “plug-and-play” system of your computer (like a USB cable). With it, you can connect an implement to the tractor and the control interface of this implement automatically appears on the main machine monitor. This has simplified daily operation, allowing producers to use one-brand tractors with third-party equipment without losing precision functionality, variable rate or section cutting.

Telemetry and predictive maintenance

The data flow does not only happen between the tractor and the implement. Telemetry allows the connected machine to send constant operating parameters not only to the mobile of the farm manager, but also to the dealer.

These reports show idle engine time, fuel consumption per operation and mechanical failure alerts. We then work with predictive maintenance. Instead of waiting for a belt to burst in the middle of a short harvest window, the system alerts days before, based on the vibration or anomalous temperature, that a part is about to fail. The exchange is scheduled for a rainy day, avoiding stops with the machine full in the field.

The big bottleneck: rural connectivity in Brazil

For much of this to work instantly, an internet connection is needed. The reality is that most rural areas in Brazil still suffer from a lack of 4G coverage.

How do manufacturers deal with this? The solution has been twofold. On the one hand, partnerships with operators for installation of private antennas in large properties. On the other, the advancement of edge computing (Edge Computing) and local storage in the machines themselves. The tractor and harvester record and process all data internally in the field to make the equipment work; when the machine goes back to the shed, where there is a Wi-Fi network, the data of the day is automatically downloaded to the platform in the cloud.

Agricultural machinery plays a key role in the modernization of livestock, contributing to the efficiency and productivity of the sector. An important aspect to be considered is the biological control of parasites, which can be optimized with the use of these technologies. To better understand how this control can be implemented, you can check out an interesting article on the subject in biological control of parasites in livestock. This approach not only improves the health of animals, but also enhances the results of machines used in the field.

The present in transition: robotics and unmanned vehicles

When we talk about a technological future, many imagine humanoid robots, but agricultural robotics already operates in more rustic and extremely efficient ways today. The transition is not theoretical, it is already running in large agricultural poles.

Tractors and autonomous vehicles

The main recent innovation in heavy machinery is the emergence of vehicles operated remotely or in a 100% autonomous way. Cabless tractors are already a reality in orchards and large plains. They use a complex array of LiDAR sensors (laser technology), radars and stereoscopic cameras to perceive obstacles.

The manager virtually delimits the area on the computer, creates the route and sends the order to the machine. If an animal or an unexpected obstacle arises in front of the tractor, it stops operation and sends an alert to the control center or the farmer's smartphone, asking for release to divert or wait. The great advantage is to solve the lack of skilled labor and allow uninterrupted shifts in the planting windows.

High capacity drones and equipment integration

Drones have gone from being mapping-only tools to becoming active application machines. Models with a load capacity of 40 to 50 liters are complementing the tasks of self-propelled sprayers.

The large sprayer takes care of the general area quickly, and the drone enters areas where heavy machinery would jam or in plots with very severe gradients.Mapping drones now send flight instructions directly to the spray drones, creating an almost fully automated chain from diagnosis to application of the defensive.

Assessing operational reality: management and infrastructure

Looking at a catalog of modern machines delights by the amount of resources. However, integrating tractors and harvesters connected to the farm requires strong adjustments in the management and routine of people.

Calculating the balance of technological investment

Machines equipped with artificial intelligence, sensor networks and data construction have a much higher initial cost than traditional mechanical equipment. The center of the purchase decision should be focused on the direct calculation of waste reduction.

For medium and large scale properties, the savings generated in limestone, potassium fertilizers, selective herbicides and the daily reduction in diesel burning tend to pay the difference in the cost of technology in two to three crops.Smaller properties need to focus on more affordable technologies, such as adaptive basic GPS equipment, or outsource highly technological services, such as drone spraying.

The new operator profile: from driver to systems manager

For a long time, the machine operator was valued for physical strength and familiarity with raw mechanics.Technological innovation has completely changed this demand.Today, operating a modern machine is very similar to being in charge of an industrial control room.

The operator does not need to maintain the steering wheel direction, since the autopilot does this. His attention is directed to up to three monitors inside the cabin.He interprets vacuum data from seed lines, adjusts pressure rates and responds to on-screen software warnings.

The lack of training of these people is the biggest source of money loss in a technological fleet. Producers buy sophisticated harvesters, but without the integration of the warehouse and field team with agronomist or technical engineers, operators tend to disable screen alerts or ignore precision systems because they find complicated. Constant training on calibration and understanding of software interfaces is no longer something restricted to the office, but the fundamental point of those who spend the day inside the tractor.
