Bavarian fertiliser spreader manufacturer Rauch is testing a prototype unit for depositing fertiliser in row crops to depths of 10 to 25cm.
The DeePot 25.1 centres around a 2500 litre hopper, the same unit supplied to the manufacturer Kuhn for its Megant drill. The layout behind the hopper sees four fertiliser delivery points carried on a folding coulter-bar that can deliver 300kg of ground pressure. Support wheels can be adjusted to suit varying row widths, while also managing depth control of the parallelogram-action linkage.
At ground level, entry is achieved with a leading disc that in turn is followed by a narrow blade assembly to part the soil. Granular fertiliser is delivered by the Turbo-S fan unit to the coulter, before the “cut” is closed by a pair of sprung press wheels.
