It’s corn! And it’s time to discuss in-crop nitrogen management of corn on this episode of the The Agronomists. Host Lyndsey Smith is joined by Jason DeBruin of Corteva AgriScience, based at Iowa, and Peter Johnson of RealAgriculture, to discuss nitrogen management, minimizing loss, when the crop needs the N. They cover when N needs… Read More

Minimizing erosion, better crop inputs management and higher corn yields is what Port Rowan, Ont., farmer Dan Petker was looking for when he adopted strip tillage five years ago. Farming with his family on the shores of Lake Erie, Petker turned to strip till — the process of minimizing tillage by cultivating eight-inch wide strips… Read More

As planting of corn and soybeans nears the finish line across Ontario, farmers and agronomists are turning their attention to weed control. A stretch of dry weather that fuelled a two-week sprint of planting, with little time for spraying, means many growers are now checking the status of pre-plant applications and trying to determine next… Read More

A widespread rain sweeping across Ontario this past weekend provided plenty of moisture to activate soil-applied, pre-plant herbicides in crop fields throughout the province. With the timely rain, many growers are now asking: after activation do these herbicides have the capability to ‘reach back’ and control already-emerged weeds and grasses such as foxtail?

A properly calibrated planter can make a key contribution to corn yield but could the planter wheels be causing yield-robbing soil compaction? Ontario Ministry of Agriculture, Food and Rural Affairs corn specialist Ben Rosser says it’s important for growers to be aware of soil compaction on or around corn rows during planting. On this episode… Read More

Where should growers place fertilizer in strip-till strips to best protect the seed from injury while optimizing nutrient uptake? Ontario Ministry of Agriculture, Food and Rural Affairs corn lead Ben Rosser says Ontario does have “safe rate” recommendations for in-furrow and 2″x 2″ planter banding but no guidelines are currently available for strip-till fertilizer placement….
