Why is there potato siccation? Can’t it be done without?

Potato siccation involves killing or purposefully drying out potato plants several weeks into the harvest. This is usually done to make the potatoes skin firm, to facilitate harvesting, to precisely define the quality of the potatoes (e.g. size, starch content), to prevent damage (e.g. second growth) or to be able to determine the time of harvest.

Unless the potatoes remain in the soil for a very long time into the fall or die because of disease or drought, their growth will only stop specifically through siccation and they will mature. It is particularly important that the potatoes have a strong skin, otherwise they may rot due to damage during harvesting or storage.


Robust and extremely powerful – the volt.cube supplies the electrical energy.


Working widths of up to 12 m allow fast and safe siccation.


The residue-free liquid lowers the electrical resistance of the plants.
