Does use of the “Dyker” reduce soil erosion and waterlogging in conventionally farmed potato fields?
Researchers of CDE are currently examining the effects of a device called “Dyker” on several potato fields in the Frienisberg area near Bern, Switzerland. The study is part of the European RECARE project. The Dyker consists of a set of wheels with three inclined shovels each. Attached to the rear end of the planting machine, it digs holes into the bottom of the furrows between the potato hills. The holes are intended to improve water infiltration and to help retain water near the plants, while preventing waterlogging and stagnant water in depressions and minimizing surface runoff and soil erosion.
