Pneumatic seeder integrated on cultivator to ensure a rapid implementation of cover crops during stubble operation at minimum costs
The Kverneland a-drill has been designed to ensure a rapid implementation of cover crop during stubble operation at minimum costs.
Two a-drill models are available depending on the seed rate/ha and the output of the machine: a-drill 200 and 500 litres.
Both models have 8 outlets which will spread the flow of seeds uniformly over the working width. In addition, they can also be used for establishing rape or a mix of different diameters seeds (leguminous plant, crucifers, ...).
|Емкость бункера, л||Крышка бункера||Вес, кг|
|a-drill 200||200||прозрачная пластиковая крышка||60|
|a-drill 500||500||прочная металлическая крышка||103|
One response to the Nitrate Directive
The nitrate directive adopted in 1991 by the EU aims to protect water resources so-called vulnerable with a rate higher than 50 mg nitrate/l. One of the measures taken into account to avoid leaching, resulting in the generalization of the soil cover in the fall by vegetation cover, which will absorb nitrogen from the soil and air, to convert it into organic nitrogen. The cover crops will then release nitrogen to the next crop (1/3), protect soil against erosion and improve its structure.
Fans adapted to seeds, working speed and width - the a-drill can be equipped with two types of fan:
The a-drills are delivered with two types of rotor: one for small seeds (rape, mustard, cabbage, clover, etc ...), and a medium rotor for seeds (vetch, grass, sunflower, ...). The agitator placed above the rotor ensures a steady stream of seeds. A brush, located at the base of the rotor, will regulate the flow and improve the setting accuracy.
For large seeds (peas, horse beans, etc ...), it is strongly advised to choose the Flex rotor option, which is able of deforming with large seed diameter.
