Ben Rosser September 24, 2019 1641 Comments Off on Will My Late Planted Corn Mature Prior to a Frost?Spring of 2019 was clearly frustrating to be a corn grower. Frequent rains and cool weather delayed planting for large parts of Ontario. A significant amount of corn was planted into June (Fig 1), and many fields tasseled in early to mid-August, later then the middle to late July we normally expect. Naturally, the common question now is what are…

As occurs most years, summer thunderstorms brought localized hail events through parts of Ontario, particularly during the last week of July (Figure 1). After a hail event, our first question is usually how much leaf tissue is still out there? When evaluating damage, it’s good to wait a week or so before going in. This gives time to let dead…
Co-authored with Ian McDonald Background OMAFRA Field Crop Unit staff have traditionally conducted an annual Pre Sidedress Nitrogen Test (PSNT) survey across Ontario at the beginning of June to measure background soil nitrate levels mineralized from the soil as an indication of year-to-year soil nitrogen status. In past years, 80-100 samples would be collected from corn fields across the province…
2017 Corn Seasonal Summary Planting The March 2017 planting intentions report by Statistics Canada estimated that Ontario farmers intended to plant 2.2 million acres of grain corn.
