The science of soil sampling

Research at a major land grant university shows John Deere ExactEmerge outperforms the standard for spacing and emergence, even at planting speeds of 10mph. Faster, more precise techniques are revamping an old practice, all a result of the rapid adoption of variable-rate application technology. (16-10)

      • 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.

              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.

                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.

                            A Penn State University finds that shredlage "does not give the cow any more physically effective fiber (peNDF) or provide any advantage over conventionally chopped silage in this aspect of the diet.” (16-05).
