What we did find was that the actual overlap estimated in theory to be more than actually what is witnessed in the field.It was also found that the larger the obstacles and the larger the equipment used, the larger the overlap. A surprising finding was how seed size affects overlap. When comparing field peas to canola it was found peas had less overlap due to the weight and mass of their seed as theyre able to clear the tubes easier than canola seed is.(Peas) land in the ground sooner than canola. That might be because canola is lighter and theyre using lower wind speeds to not shatter any of the seed coats. So, some of the canola stays in the system a bit longer, Rosaasen says.Timing also played into overlap significantly. If the equipment operator does not have the correct timings set to shut each section off, then overlap or even misses, happen. Technology that lifts openers instead of shutting off sections was found to An implement used by PAMI to seed a field where sectional control technologyhave benefits too, as it does not disturb the seed bed. was tested.That eliminates disturbance to the seed bed to the previous pass, and where that seed is placed, to ensure that you have effective seed placement and fertilizer placement as well if its an inch below or to the side of or just off to the edge of the seed row, Rosaasen explains.It was found if youre coming into the headland at an angle in your field and you are lifting sections, there can be drift on your seeding bar or tool, which causes wear on your implement. Its also important to note the study found the direction you seed your field can have a significant affect. If youre travelling perpendicular to your headlands and are shutting off your entire machine at the same time, you will reduce overlap, Rosaasen explains.PAMI tested sectional control technology from various manufacturers. To measure draft in the field, they used a load cart, Katelyn Gaetz, PAMI agronomist and project lead, explains in a phone interview. This helped them compare the draft measurements to fuel usage across the field in terms of lifting and lowering sections on a drill. They also used Solidworks, a 3D computer-aided design system, to look at theoretical overlap calculations. Setting of your equipment is crucial in any practice that you do, and utilizing these technologies, such as sectional control, you can greatly reduce overlap on the farm, which can relate to huge cost savings as well as environmental savings, Gaetz says. Depending on your scenario it will change, but you can save hundreds of thousands of dollars simply by implementing technology that would reduce overlap.The group has been receiving interest from the industry about the study.
