Making waves - Pottinger's new Wave Disc cultivation system
German manufacturer Pottinger has launched a new Wave Disc cultivation system
Cost-effective, versatile and convenient is how Pottinger describes its new Wave Disc cultivation tool system used for reduced cultivation seedbed preparation.
The new design was unveiled at a recent press event at Pottinger's seed drill production facility in Bernburg, Germany and will be available for Pottinger's Terrasem seed drills. The system will also be compatible for models with direct fertilisation.
The Wave Disc is not scalloped like a standard cutting disc, but instead has a wavy profile angled in the direction of travel. The idea is to loosen a 45mm wide strip of soil to a depth of about 60mm.
Each disc runs directly in front of the seeding coulters, loosening the ground in the vicinity of the seed, rather than wasting diesel cultivating across the entire with of the drill.
The disc throws soil across the untouched ground between the coulters, which covers any weed seedlings that would otherwise compete with the planted seed. Pottinger are calling the design a low-disturbance machine rather than a strip till system, which means in theory you can still drill into ploughing, autumn cultivations or as a direct drill into untouched land.
Pottinger claims there are five key reasons to use reduced cultivation methods:
- Low disturbance (reduced surface cultivation) in dry regions, in order to move the soil as little as possible and reduce evaporation
- In wet areas, the damp soil can only be moved very slightly in order to prevent smearing at seed slot level
- Low disturbance for grass weeds resistant to herbicide applications
- Sowing early while the soil is still very wet
- Reducing soil erosion.
Reduced soil movement in wet areas
Wet or waterlogged soil should be moved as little as possible because, in these conditions, smearing can easily take place at the seed slot level, preventing effective drilling.
