SUBSOILER

CPR ADVANTAGES OF USE 

---

Ideal soil mixing

No disturbance of soil layers

Increased crop yield

Time saving

Fuel saving

Zero maintenance cost

The CPR subsoiler is an essential machine for every professional involved in soil preparation, both in conventional and minimum tillage.It operates at a deeper level than ploughs, stalk choppers, disc harrows, rotary tillers, and clod crushers, aiming to prepare loose and porous soil. It is used for periodic deep cutting of the subsurface layer and for breaking the hardpan.

​

HARDPAN BREAKING

Vertical Divider

The hardpan is the compacted layer between the topsoil and the subsoil, caused mainly by tractor traffic. It prevents roots from reaching deeper layers to absorb nutrients and moisture. Its presence leads to:

• insufficient deep root development
  
• poor water drainage
  
• inadequate aeration of the subsoil

DEEPER ROOT

Vertical Divider

In fields with hardpan, plant roots grow horizontally because they cannot penetrate the subsurface layer. By breaking the hardpan with the CPR subsoiler, the plant develops a proper, deep root system that protects it from biotic and abiotic stress.
During hot and dry seasons, the plant can access nutrients and moisture from deeper layers. In wet conditions, water passes more easily through the fractured zones, reducing the risk of crop drowning.

PROPER SOIL AERATION
​

Vertical Divider

The CPR subsoiler improves subsoil aeration by loosening soil structure and creating a porous environment. Air circulates more effectively, reaching even the deepest layers. Roots and beneficial organisms at depth receive the oxygen they need, improving the agronomic performance of the soil.

NO MIXING OF SOIL LAYERS

Vertical Divider

The CPR subsoiler restructures the soil down to 55 cm without mixing the layers, which would degrade soil quality. The shank breaks the hardpan, while the blade makes a narrow cut in the topsoil with minimal disturbance.
Crop residues remain on the surface, improving:

• organic matter
• soil protection
• resistance to erosion caused by excess water and moisture

WATER DRAINAGE

Vertical Divider

Excess standing water indicates severe soil compaction. Water cannot penetrate the hardpan and remains on the surface.
The CPR subsoiler improves water management by creating deep channels that allow rainwater to reach the subsoil.
It also forms a water chamber beneath the subsoil: a. preventing erosion caused by stagnant water in the root zone b. giving plants access to water during dry periods

FUEL & LABOR SAVINGS

Vertical Divider

The special design of the shanks allows the CPR subsoiler to penetrate the subsoil easily, reducing fuel consumption. The rollers also improve tractor movement across the field.

ZERO MAINTENANCE COST

Vertical Divider

The shanks are equipped with a shear bolt. If a shank encounters an obstacle that applies excessive pressure, the bolt breaks to release the shank. This prevents overload that could damage the machine, the tractor, or cause an accident.
All parts are bolted and easily replaceable.

PROPER FERTILIZATION

Vertical Divider

After using the CPR subsoiler, the soil becomes more porous, allowing fertilizer to penetrate deeper and improving soil layer structure.

COMPONENTS THAT MAKE THE DIFFERENCE 

Vertical Divider

Vertical Divider

1. SHANK - Its curvature ensures easy soil penetration without overturning soil layers.

2. POINT - Ideal shape for gradual soil penetration and made from highly durable material. Breaks the hardpan and crushes clods. Reversible – can be used on both sides for extra economy. Quick installation and removal in seconds.

3. SIDE WINGS - Two side blades that cut plant residue roots and incorporate residues into the soil. Height-adjustable for different working depths. Easy to replace.

4. TOP WING - Break clods, protect the shank from wear, and reduce soil pressure.
