The efficient distribution of manure and slurry is essential for the chemical and structural correction of the soil, ensuring greater productivity and agricultural sustainability. Two of the main technologies used in this process are DPA (Proportional Feed Rate) and VRT (Variable Rate Technology). Although both have the aim of improving the application of organic fertilizers, each acts differently and can be used together to optimize results.

 

DPA - Debit Proportional to Advance

The DPA automatically adjusts the distribution rate according to the tractor's speed, ensuring that the amount of manure or slurry applied per square meter remains constant, regardless of speed variations.

Advantages
Maintains a uniform dosage and avoids waste.
Simple to operate and adjust.
Reduces the risk of over- or under-application at different points on the plot.

Limitations
Does not take into account variations in soil requirements.
Relies on prior calibration to ensure accuracy.

In the context of chemical and structural soil correction, DPA ensures that organic matter and nutrients are applied evenly, promoting improvements in water retention, soil structure and crop nutrition.

 

VRT - Variable Rate

VRT, in turn, adjusts the amount of fertilizer distributed according to the specific needs of each soil zone, based on prescription maps or real-time sensors. With this technology, it is possible to carry out a more efficient and targeted application, correcting nutritional and structural deficiencies in the soil with greater precision.

Advantages
Adjusts fertilization to the real needs of the soil.
Reduces costs and environmental impact by avoiding waste.
Improves nutrient efficiency and crop productivity.

Limitations
Requires prior soil analysis and plot mapping.
Higher initial investment due to the need for on-board technology.

 

Definition of Fertilizer Adjustments in the Use of VRT

To get the most out of VRT, you need to follow a structured process to define fertilizer adjustments in advance.

 

1. Soil Analysis and Parcel Mapping

• • Carry out soil sampling to identify nutrient and organic matter levels.
  • Use sensors, GPS, drones or satellites to map fertility variations on the plot.

2. Creating the Prescription Map

• • Based on the soil analysis, generate a prescription map with the optimum application quantities for each zone.
  • Consider the history of the plot and the fertilization objectives.

3. Configuring the VRT system on the equipment

• • Load the prescription map into the spreader or tank controller.
  • Calibrate the system to ensure that the distribution corresponds to the recommendations on the map.

4. Real-time monitoring and adjustments

• • NIR (Near Infrared) sensors can be used to measure the composition of the slurry and adjust the dose automatically.
  • The operator can monitor and correct the application via the device's terminal.

 

In short, both DPA and VRT play an essential role in organic fertilization management. DPA ensures homogeneous distribution adjusted to the speed of the tractor, while VRT allows for a more precise and optimized application, correcting specific soil deficiencies. The combination of these technologies improves the efficiency of organic fertilizers, promoting more fertile, productive and sustainable soil.

In the agricultural sector, the durability and resistance of equipment is essential to guarantee its functionality and efficiency over time, which is why Herculano has invested in the innovation and quality of its products. In this context, galvanizing has emerged as a strategic option, offering clear advantages over painting, especially on organic fertilizing equipment. In this article, we explain the different processes and cover the main differences between galvanizing and painting.

 

Galvanizing vs Painting

To better understand the advantages of galvanizing, it is important to understand the differences between the two processes:

Painting is the application of a layer of paint to the metal surface, with the aim of protecting against corrosion and improving the aesthetics of the equipment. It is a more economical process, however, in the long term it can be damaged by factors such as abrasion or exposure to chemical substances.

Galvanizing is the process of coating metal with a layer of zinc, which creates a strong protection against corrosion. At Herculano we use hot-dip galvanizing, which guarantees a thick, uniform layer of zinc that protects the metal effectively and durably.

 

This year, 2024, we have launched 2 new models of galvanized manure spreaders (HME 18 and H4R6 - images and features below) which, compared to the painted models, have a number of advantages:

1. greater durability and longevity

Galvanizing offers continuous and long-lasting protection against corrosion, with a service life of up to 20 to 30 years, resisting the most demanding agricultural conditions.

2. Less need for maintenance

Galvanizing is a low-cost maintenance solution. Even if the coating suffers scratches or damage, the zinc continues to protect the underlying metal thanks to its cathodic protection effect.

3. Resistance to adverse weather conditions

Manure spreaders are often exposed to corrosive fertilizers and other aggressive chemicals. Galvanization offers unparalleled resistance to these factors, providing effective protection against corrosion even in highly aggressive environments.

4. Greater protection against corrosion

Galvanizing creates a thick layer of zinc that protects the metal from corrosion, even in hard-to-reach areas. This means that even after long periods of use, the equipment will retain its strength and functionality.

5. Long-term cost-effectiveness

Although the initial cost of galvanizing is higher than painting, at Herculano we ensure that the added value of galvanizing is reflected in greater longevity and lower maintenance costs over time. Galvanized trailers require fewer repairs and re-applications, resulting in better long-term value for money for farmers.

6. Impact and abrasion resistance

The galvanized zinc layer is extremely resistant to impacts and abrasion, factors that are common in the use of agricultural equipment. Herculano ensures that its galvanized manure spreaders are exceptionally durable, even in conditions of intensive use.

Lubricants play a crucial role in the efficient and long-lasting operation of agricultural equipment. They ensure that moving parts operate smoothly, reducing friction and wear and preventing mechanical failures. In this article, we'll explore the various functions of lubricants and why they are essential for agricultural operations.

 

Functions of lubricants:

• Friction reduction: Lubricants reduce the resistance between moving parts, allowing them to run more smoothly and with less energy consumption. This is particularly important in agricultural machinery, where energy efficiency can translate into fuel savings and reduced operating costs.
• Wear Prevention: One of the main functions of lubricants is to form a protective film that prevents direct contact between metal surfaces, reducing wear and extending the life of components.
• Heat dissipation: During operation, machines generate heat. Lubricants help dissipate this heat, keeping operating temperatures within safe limits and preventing overheating.
• Corrosion protection: Lubricants create a barrier against oxidation and other corrosive agents, protecting metal surfaces and extending the life of machinery.
• Impurity removal: Quality lubricants can contain additives that help capture and remove contaminating particles, keeping the system clean and efficient.

 

Using the right lubricants is essential for maximizing the life of agricultural machinery and maintaining productivity at high levels. Choosing the right lubricant can mean the difference between efficient operation and costly failures. Investing in high-quality lubricants is a crucial step in ensuring the longevity and efficiency of agricultural operations.

The beneficial effects of slurry as a fertilizer are now widely recognized by farmers in general, who therefore value practices and equipment that allow slurry to be distributed efficiently in the soil.

To meet this need, Herculano has developed its own spreaders, and also sells spreaders from the Vogelsang range, a pioneering German brand in agricultural technology with very diverse and proven solutions. In the graph below we can see that, compared to other spreading methods, these solutions have practically no _NH3 emissions into the atmosphere (no odors) and, because the slurry is distributed very close to the ground, it is easier to absorb without disturbing crop growth.

 

 

We have therefore decided to compile the main features of the Vogelsang Swingup and Unispread trackers in this article.

 

SWINGUP LOCATOR

- Suitable for larger areas and greater precision in slurry application, with a variable working width of between 7.5 and 18 meters;
- Maximum precision in uniform distribution thanks to the distributors/crushers, the optimized layout of the hoses and their rigidity;
- Allows the slurry to be spread regardless of weather conditions, as it is deposited directly on the ground (minimizing the odour released);
- Due to its light weight, it requires less power to move;
- Can be adapted to existing vehicles;
- The arms fold to the side of the tank;
- It is necessary to apply hydraulic arms to the tank to support the boom and adjust the spreading height.

 

UNISPREAD LOCATOR

- Suitable for smaller areas, with widths ranging from 6 to 10.5 meters;
- More compact and economical option;
- Possibility of choosing the option with trailing shoes, a system that opens a narrow gully in the ground so that the slurry can then be deposited precisely and efficiently;
- Transport width up to 2.55 meters and height up to 3 meters;
- The arms fold up so that the whole system is stowed/folded behind the tank;
- Can be adapted to existing vehicles;
- Ideal for small working widths;
- It is necessary to apply fixed arms to the tank to support the bar;
- Can be adapted to umbilical systems.

 

Often, great results come from implementing simple improvements not only to processes but also to existing equipment.

In order to improve the performance of day-to-day work activities, we have decided to share in this article the latest options we have implemented in our product portfolio.
