Lemken MicroHub 5 adds microgranules

The latest version of the Azurit MicroHub 5 precision drill is now capable of applying microgranules in addition to soybeans and sunflower seeds. MicroHub 5 addresses increased public environmental concerns.

As fertilizer efficiency generates increased public attention, Lemken has increased their research and development into more efficient fertilizer equipment. The MicroHub 5 is the latest piece of equipment designed specifically with this factor in mind. The initial nutrient requirements of a crop can be easily covered by relatively small amounts of microgranules.

The MicroHub 5 is a spreader that allows microgranules to be applied in the direct vicinity of seeds. Microgranules contain water-soluble nutrients that are rapidly available to plants, thus producing excellent juvenile crop development. This is particularly important in cold, dry spring seasons, according to a Lemken press release. 

Bernd Valtwies, head of precision seed drill technology says, “MicroHub holds 200 litres of fertiliser which can be applied at rates ranging from one to 40 kilograms per hectare. The metering unit is operated electrically and granules are pneumatically delivered to the seed furrow. The system is controlled via the Azurit on-board terminal. This is the ultimate in precision. 

“We offer this option for our Azurit with up to eight rows. This unit is not only available for new machines, but retrofit kits will be available. A furrow former has been added to the seeding coulters to improve the quality of seed placement. The drill pipe has been updated and now comes with an inlet that can be replaced once worn.”

Apart from the proven four-row, six-row and eight-row variants with row spacings of 70 to 80 cm, the new Azurit is available with six or twelve rows with a 50-cm row spacing.

Another new feature is automatic seed singling for corn. The system monitors and adjusts the quality of seed singling. This system can be retrofitted to older machines. A new fertiliser monitoring system automatically alerts the operator if individual fertiliser coulters become blocked.
