Possible savings that can be achieved by adopting a DD system are a 70% cost saving/ha over conventional tillage and a 55% saving over minimal tillage, with labour savings/ha of 80% and 55%, respectively. The minimal soil disturbance element of the DD technique provides additional benefits, including improved soil structure, easier grass weed control, moisture retention in the rooting zone, reduced erosion, improvements in drainage and the ability to integrate cover crops into the rotation.
The DD is designed and engineered with these objectives in mind, to give optimum seed placement in a wide range of conditions, and incorporates a number of innovative designs; slim line single disc openers, adjustable disc down force, in-house designed ORGA metering system, ruggedness and simplicity.
Seeding units on the DD are mounted on spring pressurized parallelograms on mounted models, trailed models are hydraulically pressurized, which allows for contour following and down force adjustment. A single 450mm disc set at an angle cuts through the soil and opens up a trench which seed is placed into. A spiked wheel then follows which breaks the trench wall and covers the seed with soil and firms the seeding area. Row spacing is 200mm and has a drilling depth range of 12mm-100mm with manual adjustment.
All trailed DD drills are available in a seed and fertiliser configuration. The optional fertiliser kit includes a 50/50 split seed hopper (3000ltrs total capacity for 4m models, 3600ltrs 6.0m – 9m versions), separate stainless steel ORGA metering unit, transfer pipes, upstack, metering head and application nozzles. The hopper consists of a removable baffle to utilise both hoppers when applying only one product. Quick emptying slides, low level sensors, lights and a remote camera in both front and back hoppers as standard.
Dual products drilled and applied in one pass greatly reduces input costs and time, especially in a tight season. The targeted application of fertiliser into the rooting zone also means the potential reduction in product applied as nutrients are more readily available to the plant roots, reducing the potential for nutrient leaching and wastage.
