In his field in the Frisian village of Waaxens, potato seed selector Durk Bierma explains how cross planting in a 90 cm wide ridge works.

Already in 2006, the Durk and Elise Bierma- Modderman Partnership in the village of Waaxens in the Dutch province of Friesland signalled that cross planting in a 90 cm ridge provided a 10 percent higher yield of the same size. This year, thanks to a 150,000 euro subsidy from the A7/Westergo Project, they were able to introduce their more extensive once-time test and start a solid threeyear trial. LTO Noord Projects handles the coordination, while Mechanisation Company Broekens from Stiens and potato trading company HZPC from Joure contribute their knowledge and experience.
