Strip-Till is the practice that promises the advantages of both, no-till and conventional farming practices. Strip-tilling fractures compacted soil. And since strip-till does not dry out soil like conventional methods of seed bed preparation, it prevents excessive moisture loss. But because farming practices vary from farm to farm between Bergville and Koppies there is not just one Strip Till machine that will satisfy everybody.
- The farmer is able to use a standard conventional planter. (A full No-Till planter costs more than a Strip-Till machine and a conventional planter.)
- Reduced tractor numbers. Fewer tractors will be needed for planting operation.
- Huge fuel savings. The crop is planted in only three operations. Strip-Tilling, planting and spraying.
- Will speed up planting operation. (The planter that follows the Strip Till machine has no residue to manage.)
- Straight rows due to firm ground conditions.
- Will be able to plant at least a day earlier after rain versus conventional tilled lands.
- Huge conservation advantages over conventional methods. (Strip- Tilled fields showed little or no erosion after a heavy rain storm whereas conventional methods experienced high volumes of run-off and serious gully erosion.)
- No compaction on lands to prevent seed emergence due to one pass seed bed preparation. (A finer conventional seed bed compacts easily after heavy rain followed by hot sunny weather.)
- No drying out of the top soil as soil is not turned over. One plants directly into the moist soil leaving the trash on the surface. This reduces evaporation and the drying out of the soil in the seed zone.
- Improves soil health in the long term as you are only disturbing 25% of the surface area.
- Equipment needs to be set up correctly.
- Not only one or two settings are necessary.
- Each component within each row must be adjusted, set and tensioned correctly to obtain best results. Once the complete machine is set up no further hassles will be encountered.
- Knee high weeds will pose a problem as the green material wraps around the residue manager’s fingers and packs on the tines.
ALPHA II Strip Ripper
(1) A large 20 inch cutting coulter in front cuts effectively through the stubble.
(2) Two x 16 inch row cleaners mounted on large hubs with proper cub and cone bearings rake away the stubble and open up a clear path for the tine.
(3) The very strong ripper tines with a highly wear resistance tungsten face to fracture the soil up to 50cm deep.An optional beaver tail can be fitted on the backside of the shank for more soil aeration. The tines are held in the ground by a hydraulic cylinder and have a trip action when encountering stones.
(4) 18 inch wavy coulters run on either side of the tine to crumble the soil that the tine has fractured. The coulters are spring loaded and their down pressure can be adjusted. They run on an angle to form a little soil ridge behind the tine. The angle can be adjusted to determine the size of the ridge. The coulters can also be set forward or backwards to achieve a good stubble flow.
(5) A pair of paddle wheels finish off a nice prepared seed bed. The down pressure on the paddle wheels can be adjusted.
