Hail, Hail, Go Away

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 […]

Nitrogen Status in 2018 Corn Fields

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 […]

Crop response to herbicides applied prior to and after emergence.

For over 30 years, the Ontario Agriculture Weed’s team has competed in the Collegiate Weed Science Competition organized by the North Eastern Weed Science Society. In preparation for the “herbicide identification” portion of the competition, an area at the Elora Research Station is planted to a number of different crop and weed species and then sprayed […]

Verifying a Pre-Sidedress Soil Nitrate Threshold Test for Evaluating Nitrogen Top-Up Needs

Purpose: Pre-sidedress soil nitrate test (PSNT) provide a means of estimating soil nitrogen supply, and can aid producers in fine-tuning their nitrogen application rates for corn. One drawback of current soil nitrate tests is that they are only calibrated for situations where all of the nitrogen being measured has come from soil mineralization, that is […]
