Agricultural machinery, especially tractors, is an essential part of modern farming techniques, and more so when being done on a commercial scale. There are different types of tractors that are used in field operations and while tractors allow farmers to carry out field operations with great efficiency, their use may result in unwanted impacts such as soil compaction.

Soil compaction is defined as the increase in the density of the soil layers due to pressure from other external forces, affecting soil quality and crop yields. This article will delve in-depth to provide information on different types of tractors, impact on soil compaction, and also offers insights including the selection of the right tractor type with the help of agri machinery platforms like AllMachines, offering in-depth insights.

Understanding Soil Compaction

Soil compaction occurs when soil particles are pressed together, leading to a decrease in pore space, particularly due to severe rainfall or due to farming activities, such as the operation of heavy machinery. Compaction reduces the space through which air, water, and nutrients move in the soil and thus makes it less suitable for the roots of the plants. 

This obstructs the growth of crops as it prevents proper water absorption and also reduces the soil’s ability to hold moisture. As per research findings, soil compaction can reduce yields by up to 50% (US Department of Agriculture ARS, 2016¹). Therefore, it is necessary to know about the effects of soil compaction and hence, take measures for soil protection.

Factors Contributing to Soil Compaction

The weight of machinery, tire pressure, axle load, and the soil conditions during operation all contribute to soil compaction. Heavy tractors apply a significant amount of pressure on the soil, compacting it under their weight. Nearly 80% of soil compaction from wheels occurs on the first pass of the tractor¹.

High tire pressure may worsen this effect, whereas reduced pressure allows for a more uniform distribution of weight. The weight supported by each axle, known as axle load, is important, as is the frequency with which a tractor runs through the same field. Moreover, soil type and its moisture are also important in determining the susceptibility of soil compaction.

Types of Tractors and Their Impact on Compaction

Two-Wheel Drive (2WD) Tractors

Two-wheel drive tractors, such as the John Deere 5103S, are one of the most widely used tractors in agricultural operations. These are lightweight and are employed for basic operations such as plowing and sowing. They are designed to have most of their weight on the rear wheels and this may lead to compaction of the soil in specific areas. Their use can be effective where the soil is dry but where the soil is wet or soft, the rear wheels may sink into the ground and cause compaction.

Four-Wheel Drive (4WD) Tractors

The 4WD tractors, like New Holland TS6.120, evenly distribute weight across all wheels and have a lower risk of serious soil compaction. These machines are best suited for demanding tasks and are most effective in wet or uneven terrains. As these distribute the load over four wheels, they reduce pressure per unit area and hence reduce the effect on soil compaction. Despite them offering even weight distribution, their large size and weight may still cause compaction.

Track Tractors

Track tractors, like John Deere 9RX 710, have tracks instead of wheels and are specifically designed to reduce soil compaction. The tracks spread the weight of the tractor over a larger surface and also help in reducing the pressure on the ground making it ideal for use in wet or soft soils. They also provide improved traction and stability, which adds to their suitability for sensitive soils. While they offer advantages, these require regular maintenance.

Analyzing the Impact of Tractor Types on Soil Compaction

Different types of tractors affect soil compaction in different ways. For instance, two-wheel drive tractors, although cost-effective, can lead to severe compaction because of their uneven weight distribution. Four-wheel drive tractors do well in this respect, yet they still need adjustments to reduce their impact on the soil. Track tractors are the most soil-friendly option, offering reduced soil compaction and exceptional performance in tough and uneven terrains.

The composition and texture of the soil also play a crucial role in determining how vulnerable it is to compaction. Sandy soils show reduced compaction thanks to their higher porosity; however, they are prone to displacement under heavy loads.

Loamy soils, which consist of a balanced combination of sand, silt, and clay, offer moderate resistance but can compact easily when wet. Clayey soil includes fine particles, making it highly prone to extensive compaction, resulting in diminished aeration and drainage.

Best Practices for Reducing Soil Compaction

Tire and Track Selection

One of the most effective ways to minimize soil compaction is to select the right tires or tracks depending on the soil type. Low-pressure tires distribute the tractor’s weight across a larger area, decreasing ground pressure whereas tracks in track tractors offer greater benefits by distributing weight more effectively on the ground. The best way to minimize soil impact is to consider using dual or wider tires for demanding tasks.

Field Operations

Effective planning of field operations can greatly minimize soil compaction. The Controlled Traffic Farming or CTF involves restricting tractor movement to designated lanes, which ensures that compaction is limited to particular areas, thus reducing the frequency of passes and helping avoid activities on wet soils.

Tractor Configuration

A tractor’s configuration can also be incredibly helpful in reducing soil compaction. The even distribution of ballast makes sure there is consistent weight distribution on the ground. Tire pressure is also adjusted based on the soil which can help avoid soil compaction.

Future of Tractor Design and Soil Compaction Management

Modern tractor designs now have improvements that help minimize soil degradation. Autonomous tractors that come equipped with sensors and AI are very precise in fieldwork, make fewer passes in the field, and have better weight distribution which reduces soil compaction. 

There are also innovations in tire and track technology that offer enhanced solutions for reducing ground pressure. The use of lightweight materials and energy-efficient designs are also being looked into to build tractors that offer power and are also soil-friendly. These innovations could drastically enhance efficiency and ensure sustainability.

Conclusion

Soil compaction remains a big challenge in agriculture these days as it affects soil quality and crop yields. The type of tractor also affects the degree of compaction of the soil. The two-wheel drive (2WD) tractors are more flexible, but due to their uneven weight distribution, they can cause soil compaction. The four-wheel drive (4WD) tractors, for example, the Kubota compact tractor have better weight distribution on the ground.
