Seeder Lemken Azurit, Kyiv region.

DeltaRow consists of staggered two-row rows, located at a distance of 12.5 cm from each other. Since the rows are created synchronously, the seeds are securely placed in the triangular grid.

Compared to single-row technology, DeltaRow offers a 70% improvement in the area available for planting and growth, resulting in more water, nutrients and light for crops.(//tractor-service.com)
A band of fertilizer is placed in the area under the roots inside the DeltaRow. This allows you to design the planter symmetrically.
The technology offers a clear advantage in fields prone to erosion, as a better root system compared to a single row.
