Cost-effective, extremely versatile and convenient is how Pottinger describes its new Wave Disc cultivation tool system for seedbed preparation.
Effective in dry or wet conditions Pottinger say the cultivation tool is perfect for reduced soil cultivation whilst at the same time increasing yield.
The Wave Disc is available for the Terrasem R3 and R4 as well as Terrasem C4, SEM C4, C6, C8 and C9 seed drills and all models with direct fertilisation.
Soil conditions that make it necessary to use reduce cultivation are:
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.
The Wave Disc cultivates the soil in water-saving strips: only the band either side of the seed slot approximately 50 mm wide is disturbed, the rest of the surface remains untouched, providing effective reduction in evaporation. Moisture levels are retained by the uncultivated soil. At the same time reducing the cultivation area to strips protects against erosion. In addition, sufficient tilth remains for plants to develop perfectly during the germination stage.
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 that prevents effective drilling. This problem occurs especially in locations with wet soil such as black soils in the spring or waterlogged soils with limited surface drying. In these situations it is important that no deep cultivation equipment is used below seed slot level. The Wave Disc does not penetrate the lower soil structure and does not move the soil to the side. That is why smearing does not take place and the seed can be perfectly placed in the loosened strips.
