WTSIP has invested in two new minimal tillage implements that are available to trial for free on your farm's soil types and conditions.
They are referred to as strip tillage or vertical tillage implements. They are a variation on zonal tillage that are used on the Tablelands but they have not been adopted anywhere else in the Wet Tropics.
We are interested to find out if they could be useful to other growers.
What are they?
Both implements use straight, vertical coulters cut to a 'saw-blade' design. They cut any crop or cover-crop residues and penetrate the ground to approx. 200mm, taking a portion of the residues with it and pinning it below ground – all with very minimal disturbance to the soil surface.
They have the potential to be used in multiple variations and combinations with other fertilising, cover-crop planting and minimal tillage equipment.
- Sub-surface pinning a portion of cane trash into the crop zone in ratoons
- De-compaction and aeration of the crop zone in ratoons
- Sub-surface pinning a portion of cane trash into the crop zone in spray-out fallow
- De-compaction and aeration of the crop zone in spray-out and cover-crop fallows
- Direct-drill planting of cover-crops into cane-trash for fallow including sub-surface pinning a portion of cane trash
- Direct-drill planting of companion-crops into ratoons including sub-surface pinning a portion of cane trash
- Knock-down & partial incorporation of cover-crop residues
- Minimal cultivation for near-zero till cane planting including sub-surface pinning a portion of cane trash
- Minimal cultivation where smoothing of traffic areas is required
- Minimal cultivation for drainage in the inter-row in place of coulter-ripping
- De-crusting of surface-applied mill-mud including sub-surface pinning a portion of cane trash (& mud)
- Sub-surface fertilising, including sub-surface pinning a portion of cane trash
Trying them out
The two implements are available to try for free to any growers in the Wet Tropics. Transportation to your farm is also free.
The only thing we ask is that you complete an evaluation form - we want to know what you think of the implement, if you would use it and how, and any ideas you may have for improving them.
The implements are based at:
