If agriculture wants to reduce the potential impact neonicotinoid seed treatments have on pollinators, it has to modify standard vacuum planters. That’s the verdict from Ridgetown College, University of Guelph researcher Dr. Art Schaafsma. “Essentially, what we’ve created is a drift problem,” says Schaafsma, who spoke publicly about his research for the first time last… Read More

If a corn plant emerges one, two or three days after its neighbour, will it yield less? Real Agriculture resident agronomist Peter Johnson is determined to find out. At the SouthWest Ag Conference last January, National Corn Growers Association yield contest champion Randy Dowdy challenged growers to plant a flag test on their farm to… Read More

When farmers search for ways to better manage cover crops, seed treatments such as neonicotinoids don’t readily come to mind. But that could change if research results from University of Guelph weed scientist Dr. Clarence Swanton are proven in field tests. In this episode of Corn School, Real Agriculture resident agronomist Peter Johnson sits down with… Read More

Consistent planting depth and even emergence — it’s every corn grower’s goal, but it can be difficult to achieve. In this Corn School episode, AGRIS Co-operative agronomist Dale Cowan takes a close look at the impact planter down force can play in helping (or hindering) growers in their quest for an evenly spaced, picket fence… Read More
