Terraland deep rips while it mixes soil for a rich seedbed

The Terraland TO offers a winning formula for current soil requirements across the country. It is able to work across a 6m (20ft) cut as it works down to a 550mm (22-inches) depth while also mixing to a depth of 350mm (14-inches)

When Morawa WA farmer Grant Borgward first saw the Czech-made Terraland TO deep ripper he knew it was going to be a perfect fit for many local growers.

The versatility of what was both a giant ripper that excelled in heavy soil conditions but could also be set to renovate in lighter soil conditions was the clincher for Grant.

The Terraland TO, had a winning formula for current soil requirements across the country.

It was able to work across a 6m (20ft) cut as it worked down to a 550mm (22-inches) depth while also mixing to a depth of 350mm (14-inches).

It will take tractor power from 368 to 441kW (500 to 600hp) to run the arsenal of 13 tines at a spacing of 430mm (17-inches) across 6m (20ft) with a big advantage that the unit will fold to 3m for transport.

Following some very impressive trials in WA that showed improvement soil pH within one year, Grant went onto become the distributor for manufacturer Bednar.

Terraland distributor and Morawa WA farmer Grant Borgward is now the Bednar agent for the Terraland deep ripper that also covers as a multi-purpose chisel plough to renovate lighter soil structures as well

During the ripping season in Geralton WA, the Terraland TO 6000 had its depth set at 550mm (22-inches) as it was pulled by a Case IH Quadtrac running at 7.5kph.

The Terraland TO 6000 worked two rows of heavy-duty tines with 80mm long-life carbide and hard-faced chisel points sitting below a wing assembly that effectively had the job of mixing the soil.

The technology behind the Bednar Terraland is ideal for the Geraldton WA cropping area. It is designed to incorporate lime and organic matter deeper into the soil profile and remove hardpans down to a 550mm (22-inches) depth.

Geraldton’s cropping area is mainly light sandy soils that can all too readily compact and harden. Often leaving the plant roots unable to reach the deeper soil profile.

Using the Terraland will save more plants in the dry season when the roots are deep enough and reach the wet soil.

The shape of the Terraland tine matched with the 80mm chisels did a great job of bringing up the soil from 550mm (22-inches) where there was a higher clay content.

This increased the soils nutrient holding capacity and Potassium content of the topsoil.

It also reduced non wetting sand as it is diluted with clay resulting from the mixing action.

The Terraland left the soil enriched with extra nutrient mixed well throughout the profile with no hard pans and the rear tandem spiked rollers that followed also added to the final soil incorporation and levelling.

The soil at Geraldton was left in excellent condition ready for seeding.

During the cropping season it was evident there was a more significant yield in the trial zone when compared to other areas in the same paddock that weren’t ripped with the Terraland.

The build of the Terraland TO is proving readily adaptable to our tough local conditions.

The finish is important – while the Terraland TO is effectively designed for intensive tillage at depths down to 550mm (22-inches) across a 6m (20ft) working width and mixing to a depth of of 350mm (14-inches) – it’s the rear tandem spiky roller that completes the incorporation, followed by V-shaped rollers for levelling out to a perfect finish for planting

The central frame is fixed with four anchor points to take any strain while the working section frames are built from 150x150mm (6×6-inch) RHS profile for high resistance.

If growers strike wet conditions and want to work without the roller, they can rely on the transport axles between the tines instead.

The technology behind the Bednar Terraland is to serve the growing trend in the northern hemisphere to help farmers  bring back to the surface the rich potassium and clay particles from the sub-soil.

Direct drilling has changed soil profiles in many areas to the degree that low yields are making some cropping zones unprofitable to plant.

Deep ripping into the profile is also adding a higher clay content that is consistent with increasing the soils nutrient-holding capacity.

This has the benefit of reducing the non-wetting sand content as it is diluted with clay resulting from the mixing action of the Terraland.

In the case of the Terraland you can expect it to leave the soil enriched with extra nutrient mixed well throughout the profile with no hard pans down to 550mm (22-inches) as it firms and evenly mixes the topsoil with the double spiked roller.

The Terraland TO 6000 can operate with a range of blade widths from 40 to 125mm (1.5 to 5-inches) so it’s convenient to set the machine up to match the required amount of mixing and ripping for the soil condition in each paddock.

Terraland has firmly adapted its range to work deeper for higher yields.

The approach to achieve this result is in its ability to reduce hard pans across the paddock, and oxygenating the sub-soil while bringing previous lost nutrients up from below.

Through mixing and activating the soil to release tied up nutrients, it also has the benefit of reducing waterlogging and packing the surface to reduce moisture loss and stop erosion.

The Department of Primary Industries and Regional Development is also getting behind the deep ripping below 500mm (20-inch) call, as they claim for paddocks lacking nutrients or suffering sub-soil acidity, it results in an additional one tonne of yield for each hectare.

Emphasis has to be placed on mixing sand and clay evenly to help improved soil structure.

Following countless seasons of direct drilling it is estimated almost every farm has patches of some form of hard pan at around 125 or 150mm (5 or 6-inchs) of depth, and in many more cases some form of top soil or sub-soil acidity.

In addition, many more cropping areas are suffering from minor to extreme areas of non-wetting sands.

This is why the Terraland system has been developed to offer growers the chance to super deep rip or depending on circumstances, operate at the varying depths required to improve many different soil types.

The Terraland TO method is referred to as action renovation tillage in the northern hemisphere where it has done much to improve so much of the damaged soil and most often in just one pass.

Much of the obvious benefit has been gleaned from the shape of the tine and the mixing wings on either side that are able to ensure a thorough mixing of the soil beneath the surface.

While the giant double spiked rollers mix the topsoil and pack it down firmly to lock in the moisture and level the paddock for a perfect seed bed.

This process also leaves behind a dimple pattern on the surface and this has proven to be the best prevention for wind erosion, but also allow water infiltration to pick up the benefit of any rain.
