Single-seed drilling with DeltaRow

Placement in a triangular seeding pattern for agronomic and operational benefits

In its Azurit single-seed drill, LEMKEN has opted for the novel DeltaRow technology, which provides each and every plant with 70% more surface area for growth than conventional placement in single rows. This in turn ensures plants have better access to light and are better supplied with water and nutrients. As a result, higher yields can be reliably generated from marginal locations. The improved soil cover will also additionally protect against erosion.

DeltaRow technology involves a singling unit depositing seeds in an extended furrow comprising twin rows spaced 12.5 cm apart. Seed singling is performed by two synchronised perforated discs offset against each other by half a grain spacing. As each of the perforated discs only singles every other seed, their diameter can be kept narrow and their circumferential speed be minimised. The greater time interval available for singling results in outstanding quality of placement at high speeds of travel. A fertiliser band is placed centrally underneath the DeltaRow. Placement in a triangular seeding pattern ensures that seeds are positioned optimally in relation to fertiliser and obtain maximum benefit from it.

DeltaRow crops can be easily harvested with current silage and grain maize harvesters. Trials conducted over several years have confirmed that this technology allows higher yields to be achieved. LEMKEN will launch its DeltaRow seeding technology on the market with its new Azurit single-seed drill.
