  • University Test Study

    ExactEmerge™ scores high marks during in-field testing

    Research at a major land grant university shows John Deere ExactEmerge outperforms the standard for spacing and emergence, even at planting speeds of 10mph.

    • Corn Field up close

      Most critical factor of corn yield during in-field testing

      University of Minnesota research on emergence, timing, population, and spacing found that uniform emergence has by far the largest impact on yield, up to 9%.

        Don’t let uneven emergence rob your yield

        A recent study by Purdue University identified the top factors of corn yield: even emergence, soil moisture, soil temperature, and seed-to-soil contact. Of these, even emergence had the largest impact on ultimate yield.

          Want to maximize corn yield potential? Follow these four keys

          Make no mistake, planting is the most critical aspect of the production cycle. So it's important to lay a strong foundation to reach the full potential of your operation. But there are four aspects that stand out the most.

            You Can't Argue With Results

            We ran the tests … and so did Purdue University. Here’s the plain truth: running at faster speeds with ExactEmerge™ has no negative effect on accuracy. So whether you’re bumping up from 5mph to 7mph, or 6mph to 8mph, or higher, you get all the agronomic benefits to help maximize your full yield potential with the added bonus of increased planting speeds to take advantage of short windows.

                  Save up to 30% on inputs with automated guidance and section control

                  Research at Auburn University showed a possible 30% in overall savings when using section control and guidance together. So investing in precision guidance is really a no-brainer.

                    Automated section control pays for itself in 2 years

                    This 2011 study from Auburn University shows that using automatic section control during planting delivers input savings from 1% to 12% on each pass, with an average seed savings of 4.3%. Investing in section control technology will pay for itself within 2 years.

                          Is one banding system – side band or mid-row band – better than the other? Some of our competitors would have you think yes … mid-row. But the truth is there is no agronomic advantage of one of these placement practices over the other. And that’s not our word. That comes straight from the Prairie Agricultural Machinery Institute (PAMI).
