At the completion of bluegum or pine plantation harvesting, we use our powerful, application specific machinery to grind the stumps to a given specification below ground level. All of the root matter and trash in the path of the machine is ground and mulched into the soil structure in one pass. Typically the grinding depth is 100mm below original ground level. This creates a consistent seed bed and ensures there is no regrowth from the stump. Productivity is between 1 acre and 1 hectare per hour.
STICK RAKING AND TRASH CONTROL
The stick raking pass collects nearly all of the trash and debris which has been dropped on the ground during harvest and forms windrows. These windrows can sometimes be burnt depending on result and local conditions or we mulch them with a different machine
When the windrows of trash have been formed we use our mulching machines to mulch the debris into the ground where it will decompose into the soil structure
The disc ploughing serves two purposes, 0ne, break up the top soil (as the ground would not have been cultivated for over 10 years) and to provide loose dirt to level. It will also break up and of the smaller sticks and trash which get left behind when raking
Lime and Fertiliser applications
We have consistently found that the ground after a Bluegum rotation required the same inputs as the neighbouring ground which has not had trace elements applied for long periods. There is no evidence to suggest that the bluegum plantation removes soil elements any worse than a normal cropping cycle
This is recommended where improved pasture or cropping programs follow the remediation process. The levelling provides a more consistent seed bed, reduce air gaps and maximise seed germination. This is also naturally provides the benefits of level ground for agricultural practices in general.
crop and grass seeding
At the completion of all previous passes the land is immediately available for a normal agricultural cropping or pasture program relevant to the season timing. There is absolutely no requirement for settling time or waiting period until production can start.
