Corn Planting Deadline Extended for Some Ontario Farmers

Farmers in parts of Ontario are being given more time to plant corn this year - but only a few extra days. 

Provincial crop insurer Agricorp said Friday it would extend the corn planting deadline in Lambton, Middlesex, Niagara, Chatham-Kent, Essex, and Elgin until June 18. The usual deadline for the same counties is June 15. 

Overly wet conditions have badly delayed corn – as well as soybean – planting in various parts of the province. The latest field observations from the Grain Farmers of Ontario on Thursday pegged Ontario corn planting at about 90%, with soybeans at around 80%. However, the same report noted that some areas still had “significant” acreage still to be planted. 

Forecasts for southern Ontario this week are for potentially record-breaking heat, along with chances of scattered thunderstorms and showers. 

According to Agricorp, decisions to extend planting deadlines for production insurance require approval from the Ontario and federal governments. Other criteria for extensions include agronomic impacts, crop conditions surrounding the planting dates, and crop viability. 

Decisions to plant within the extended planting period are left up to individual farmers.

Supplemental Nitrogen on Soybeans: Can Early Nitrogen Increase Yield?

Video: Supplemental Nitrogen on Soybeans: Can Early Nitrogen Increase Yield?

Can supplemental nitrogen help soybeans reach higher yield potential? Technical Agronomist Tim Sickman walks through an ongoing trial at the Nutrien Innovation Farm in Owensboro, Kentucky, exploring whether a modest amount of nitrogen applied at planting can support higher-yielding soybean environments.

The trial compares 30 pounds of supplemental nitrogen across both 15- and 30-inch rows, along with treatments that include sulfur and micronutrients. Similar trials conducted in 2024 and 2025 delivered a six- to seven-bushel yield response, prompting the team to expand the research this season.

Early observations show that treated soybeans are slightly taller and averaging about two additional nodes on the main stem. These added nodes could create more opportunities for blooms and pods, but the true results will come at harvest when the team evaluates pod development, seed fill and final yield.
